He was born in 1913 so next year sees the centenary of his birth. Stanley became Senior Editor of this journal in 1963, and retained that title, the equivalent of chairman of the board, until his death. Other ornithological distinctions included a spell as President of the BOU, Chairman of the Scientific Research Committee of the BTO during an important phase of that organisation’s expansion, and another spell as Chairman of RSPB Council. But it was as Chief Editor and driving force behind the BWP project for which Stanley Cramp will be best remem- bered. To read more about his life and his accomplishments, I can do no better than refer you to the various obituaries published after his death, including one by Max Nicholson in BB (Brit. Birds 81: 10-13) and also a much more detailed appreciation, by fellow BWP co-editor Ken Simmons, pub- lished in BB in 1992 (Brit. Birds 85: 387-414). Both of these are freely available online at the BB website, www.britishbirds.co.uk The purpose of this editorial is to intro- duce a series of papers that have been com- missioned to mark Stanley’s centenary year and the 25th aniversary of his death. The Editorial Board’s aim was to choose three or four of the areas of ornithology that were of particular interest to Stanley and look at changes and developments in each particular field during the past 50 years or so. The first of these appears in this issue and looks at the breeding birds of Inner London. Having moved to London as a young man in the late 1930s, Cramp soon became immersed in various aspects of London’s birds. One of those was the roosting behaviour of Common Starlings - check out the photo- graphs of Stanley catching roosting Starlings in London in about 1950, on p. 397 of Simmons’s article - health and safety officers take note! In this issue, Ian Woodward and Richard Arnold, two modern stalwarts of the London scene, present a fascinating update of the bird populations in the British capital. As someone who visits London two or three times a year, usually for meetings or to catch a flight to somewhere ‘better’ for birding, I am dimly aware of London’s birds, and have even seen a few decent migrants there, mostly at the London Wetland Centre, since I started working for BB. But the diversity of London’s avifauna and the population trends revealed in the recent atlas work show that there is a great deal more to London than pigeons, parakeets, and the occasional rarity. Among Stanley Cramp’s other particular interests were the effects of pollution on birds and the wider environment, and seabirds - Stanley was the lead author of The Seabirds of Britain and Ireland (Collins, 1974), the book that brought us the results of Operation Seafarer, the first national census of the seabirds of Britain and Ireland. Papers on both of these topics will follow in the next few months. As this issue drops onto your doormat, staff at BB and hundreds of other bird- related organisations will be fine-tuning their preparations for the coming British Bird- watching Fair. In order to attract the crowds, the pre-event advertising usually majors on the wildlife celebrities who will be attending. I certainly enjoy watching out for the big names, either coming over to or passing our stand, although I am more likely to remember someone who I know has made a lasting contribution to ornithology or conservation than someone I might once have seen on the telly. Thirty years ago I’d have been looking out for Stanley Cramp, although, with a smoking ban in the mar- quees, he might not have been at the stand very long! Roger Riddington 432 © British Birds 105 • August 2012 • 432 The changing status of the breeding birds of the Inner London area Ian Woodward and Richard Arnold Abstract London’s birds have been studied in detail for about 120 years. Stanley Cramp was co-author of two important papers in British Birds looking at the birds of Inner London during the first half of the twentieth century, the first of which summarised records from 1900 to 1950, and provided a baseline for future studies. The London Natural History Society has since completed two atlas projects to map breeding bird distribution and is close to completing a third atlas project. This paper looks at the changes that have occurred since the period covered by Cramp’s first article (I 900-50). An overview of changes in Inner London is followed by more detailed accounts of selected species groups. The number of species nesting annually in Inner London has increased steadily, from around 32 in 1950 to about 60 today. Waterbirds have done particularly well, and the successful return of raptors to the city has also been welcome. The fortunes of passerines have been mixed. Introduction The sprawling city of London stretches for approximately 10 miles (16 km) or more north and south of the River Thames, pro- viding homes, workplaces and recreation for the city’s inhabitants. Greater London has 7.8 million residents (ONS 2011) and that number is swelled considerably by regular commuters. Most people follow their daily routines without visiting the green spaces that comprise 38% of the city’s total area (Greenspace Information for Greater London, www.gigl.org.uk); they see little of London’s wildlife and are unaware of how many species survive and prosper in the city. Yet dedicated birdwatchers and naturalists regularly work the many parks and open spaces in London: Hyde Park and Kensington Gardens, The Regent’s Park, Battersea Park, Wormwood Scrubs, Hampstead Heath and Brent Reservoir (for example) are all well- watched areas where in the region of 100 bird species may be seen during a calendar year. Birdlife is not restricted to the parks, and the Black Redstart Phoenicurus ochruros , perhaps © British Birds 105 • August 2012 • 433-457 London’s most iconic bird, is more likely to be found in office courtyards. The London Natural History Society (LNHS) dates back to 1858, though the current name was chosen in 1913 (Montier 1977). The ornithological section has recently been rebranded as the London Bird Club, but remains an integral part of the LNHS. The LNHS recording area is defined as a circle with a 20-mile radius centred on St Paul’s, and thus includes significant areas of coun- tryside beyond the built-up area of Greater London. Fig. 1 shows the LNHS recording area, together with Inner London, the Wat- sonian vice-counties (which are still used for biological recording), and modern-day Greater London. One of the earliest detailed accounts of London’s birds dates back to the late nine- teenth century (Hudson 1898). Max Nicholson wrote another early report, based on his observations during 1924-26, which remained unpublished until 1995 (Nicholson 1995). In 1929, Holte MacPherson defined ‘Inner London’ as a rectangular area, eight by 433 Woodward & Arnold five miles and centred on Charing Cross, and composed a list of the birds found there (MacPherson 1929). Thereafter, an annual update was published in BB until 1950. In 1945, Richard Fitter published London's Natural History, which describes the develop- ment of London and the impact on its flora and fauna, especially birds, covering the Middle Ages up to the time of publication. Stanley Cramp moved to London in 1938 and a few years later began observing birds in the central London parks, renewing a love of birds that had begun during his childhood (Simmons 1989). From the late 1940s to the mid 1960s, he was a regular contributor to the annual London Bird Report (first produced by the LNHS in 1936, and in which MacPherson’s Inner London area became one of the recording sectors), and published studies of four of the Royal Parks and of two stretches of the Thames in Inner London. In BB, Cramp co-authored a description of the changes to Inner London’s birdlife during 1900-50 (Cramp & Teagle 1952), subse- quently updated by Cramp & Tomlins (1966). Stanley Cramp was also one of many con- tributors to the LNHS summary of London’s birdlife in the first half of the twentieth century, originally published as a New Natu- ralist title (LNHS 1957, 1964). The LNHS has since completed two atlas projects that have Legend , - - Greater London l — Urban Area , - - Watsonian t - - Vice-counties *■ / ^ 1 . far N orth Ess ex .

A Feral Pigeon Columba livia in Trafalgar Square. The Feral Pigeon is perhaps the archetypal ‘London bird’, but the capital has a great deal more to offer birdwatchers than this and in the past 60 years the species gains have considerably outweighed the losses. mapped the distribution of London’s birds during the breeding season. The first atlas, to which Cramp contributed, covered the period 1968-72 (Montier 1977), and the second covered the period 1988-94 (Hewlett 2002). Oliver (1997) used data from these two projects to provide an update of the changes in Inner London1 since the account by Cramp & Tomlins (1966). A third atlas project, mapping the distribution of both wintering and breeding birds in London, began in 2008 and is scheduled to finish in 2012. When comparing Cramp’s observations with those of subsequent observers and with what we see today, it is obvious that London’s birdlife is far from static, with species gained and lost as well as population fluctuations. Arguably, the story of London’s avifauna in the last half century is all the more fasci- nating because so many different species are living in close proximity to humans. This paper looks mainly at the changes in London’s breeding birds since Cramp tk Tomlins (1966), with some asides into London’s wintering birds, and draws heavily on data from the three atlas projects. In a few cases we have looked back further, to Hudson and/or Nicholson. We have focused predomi- nantly on Inner London, as this was the area studied by Cramp, but we also discuss how some changes relate to the wider LNHS area. For data prior to the current atlas, where no reference is given in the text, the information is taken either from Hewlett (2002) or from London Bird Reports. Overview In his articles with Teagle and Tomlins, Cramp noted that around 32 species were breeding annually in Inner London in 1950, including seven species that had become 1 Oliver’s Inner London area is based on Atlas tetrads and is around 7% smaller than the actual LNHS Inner London area. Oliver’s area excludes strips of c. 0.5-km width to the east and west, and of c. 400 m to the north. However, it includes a 400-m-wide strip to the south which is actually outside Inner London. The same Inner London area (i.e. that based on tetrads) is used in this article when discussing the 2008-1 1 Atlas data.

The Common Coot Fulica atra first bred in London in 1926; initially found predominantly in St James’s Park, it was one of the first London birds that a young Stanley Cramp studied in detail. regular breeders since 1900 (most since 1925). The additions were Tufted Duck Aythya fuligula, Common Kestrel Falco tin- nunculus, Common Coot Fulica atra, Eurasian Jay Garrulus glandarius. Black Red- start, Pied Wagtail Motacilla alba and Goldfinch Carduelis carduelis. By 1965, Canada Goose Branta canadensis, Common Pochard A. ferina, Herring Gull Larus argen- tatus and Bullfinch Pyrrhula pyrrhula had also been added to the list, the first breeding records for Great Crested Grebe Podiceps cristatus, Eurasian Sparrowhawk Accipiter nisus and Grey Wagtail M. cinerea had occurred, but Little Grebe Tachybaptus rufi- collis and Stock Dove Columba oenas had been lost from Inner London as breeding species. The loss of Stock Dove was only brief, and it had returned by the time of the 1968-72 Atlas, which also documented the first Inner London breeding records for Grey Heron Ardea cinerea. Magpie Pica pica, Goldcrest Regulus regulus and Long-tailed Tit Aegit- halos caudatus in the twentieth century, as well as the return of House Martin Delichon urbicum after an absence of 80 years. Oliver (1997) reported that two species, Western Jackdaw Corvus monedula and Tree Sparrow Passer montanus, had been lost as breeding birds in Inner London in the 16 years between the first two atlases1, and that three, Tawny Owl Strix aluco, Song Thrush Turdus philomelos and Spotted flycatcher Muscicapa striata, had shown constant declines. In contrast, 24 species were more common and 20 species were recorded that had been absent in the first survey. These gains are notable, even allowing for the fact that they were exaggerated slightly by the temporary availability of some derelict land and water in the Surrey Docks area. Oliver’s species list is reproduced in appendix 1, with additional columns to show changes between Cramp’s time and the current atlas project. Even though the latter is still ongoing, coverage has been extremely good in Inner London, so we can be confi- dent that the data are reliable, although there may be some minor changes in the final pub- lication. During 2008-1 1, a total of 13 species were recorded in Inner London for the first 1 In fact, although Tree Sparrows bred in an Inner London Atlas tetrad, the colony was actually outside the true Inner London area (Montier 1977). 436 British Birds 105 • August 2012 • 433-457 The breeding birds of Inner London time during atlas breeding surveys, six of which bred (Egyptian Goose Alopochen aegyptiaca, Common Shelduck Tadorna tadorna, Gadwall Anas strepera , Hobby F. subbuteo, Great Black-backed Gull L. marinus and Little Owl Athene noctua). This total excludes the non-native Black Swan Cygnus atratus and Bar-headed Goose Anser indicus, and also Red-crested Pochard Netta rufina, which was not mapped in 1988-94 owing to its uncertain status. A further 22 species were more widespread than in 1988-94, including nine species that bred in Inner London for the first time during atlas survey years (Man- darin Duck Aix galericnlata, Little Grebe, Peregrine Lalcon F. peregrinus, Common Tern Sterna hirundo , Rose-ringed Parakeet Psittacula krameri , Green Woodpecker Picus viridis, Sand Martin Riparia riparia , Common Whitethroat Sylvia communis and Reed Warbler Acrocephalus scirpaceus). In comparison, nine species have been lost as Inner London breeding birds since 1994, three of which were only transient breeders in the Surrey Docks area (Skylark Alauda arvensis, Yellow Wagtail Motacilla flava and Reed Bunting Emberiza schoeniclus ), and a fourth that also relies on temporary sites in London (Little Ringed Plover Charadrius dubius). The other losses were Collared Dove Streptopelia decaocto, Willow Warbler Phyllo- scopus trochilus, Spotted Plycatcher, Lesser Redpoll Carduelis cabaret and Bullfinch. Col- lared Doves bred unsuccessfully in St James’s Park during the second atlas period, in 1989, but this was unusual so it is perhaps mis- leading to include the species as a loss. In fact, sightings from six Inner London tetrads and confirmed breeding in five adjacent tetrads suggest that the Collared Dove may be finally about to colonise Inner London. In addition to the losses, a further six species (Kestrel, Tawny Owl, House Martin, Eurasian Treecreeper Certhia familiaris , Song Thrush and Linnet C. cannabina) have suffered range losses within Inner London during the period. Using Cramp’s 1965 list as a baseline rather than 1994 data, the gains are even more striking. The number of species which bred regularly in Inner London in 1965 was 34, but this had increased to 60 by 201 1. Just three of the regular breeders from 1965 have been lost (Jackdaw, Spotted Plycatcher and 234. Great Cormorants Phalacrocorax carbo against a backdrop of Canary Wharf. The Great Cormorant was a rarity in London in the early part of the twentieth century, but is now a common sight in central London and at least eight breeding sites were registered in the LNHS area during the current atlas. British Birds 105 • August 2012 • 433-457 437 Erica OlsenIFLPA M/ke Lane Woodward & Arnold Bullfinch). Although some species are in decline, including the once numerous House Sparrow Passer domesticus, the variety of birdlife in Inner London is greater than at any time for at least 120 years. Several of the changes within Inner London and across the LNHS area can be linked to wider UK trends. Willow Warbler, Song Thrush, Spotted Flycatcher, Linnet, Lesser Redpoll and Bullfinch are all red- or amber-listed following long-term breeding population declines (Eaton et al. 2009). Spotted Flycatchers have been recorded breeding in just 4% of tetrads in the LNHS area during the current atlas (having been present in 64% in 1988-94, with breeding evidence recorded in three-quarters of those), while the Lesser Redpoll is also now more or less extinct as a breeding bird in the LNHS area. Looking beyond Inner London, Turtle Dove Streptopelia turtur, Willow Tit Poecile montana, Marsh Tit P. palustris, Wood Warbler Phylloscopus sibilatrix. Tree Sparrow, Yellow Wagtail, Tree Pipit Anthus trivialis, Hawfinch Coccothraustes coccothraustes and Corn Bunting Emberiza calandra are other red- or amber-listed species that bred in Greater London in the 1960s but have since suffered severe range declines. Willow Tit and Wood Warbler are now gone from the LNHS recording area, while the others are left just clinging on. Clearly, some of the changes in London’s birdlife are likely to be habitat-related. New habitats were created inadvertently through war-time bombing and when industrial sites, such as the Surrey Docks, became derelict (Grant 1971). These habitats are temporary and soon lost through redevelopment. More recently, sites have been created or managed specifically for wildlife, such as at the London Wetland Centre. Other changes in bird popu- lations are no doubt driven by regional and national trends, in turn linked to factors such as persecution, pesticide use and farming practice. Improvements in air and water quality are also likely to have affected bird populations in London. The remainder of this paper looks in more detail at some of the species groups breeding in Inner London. Waterfowl As well as the Thames, wetland habitat in the form of canals and lakes can be found in central London. Most of the larger parks have one or more lakes, often with islands that 235. The Canada Goose Branta canadensis is now widespread in London and, like several other species of waterfowl, is more numerous than half a century ago. 438 British Birds 105 • August 2012 • 433-457 The breeding birds of Inner London Fig. 2.

In Inner London, Regent’s Park, Hyde Park, St James’s Park, Battersea Park, Vic- toria Park and Southwark Park all have lakes with islands, while Kensington Gardens and Burgess Park have lakes without islands. Atlas data show that water- fowl continue to prosper in Inner London and the same is true of Greater London, with its reser- voirs, gravel-pits, the Thames marshes and its tributaries. The capital now also boasts two major wetland reserves, Rainham Marshes and the London Wetland Centre, the latter just 1 km west of Inner London. The populations of all of London’s waterfowl have expanded since Stanley Cramp’s time. Nat- uralised species feature prominently, particularly geese. Canada Geese were already breeding in Inner London in the 1960s, after fully-winged birds were released in Hyde Park in 1955 (Cramp & Tomlins 1966), and by the late 1980s they were widespread on rivers and canals as well as in London’s parks. Feral Greylag Geese Anser anser became estab- lished in central London in the 1980s, appar- ently after young from the St James’s Park collection were left unpinioned (Oliver 1997). The Greylag Goose has now spread widely and small numbers can be found among the Canada Goose flocks in many London parks. Egyptian Geese first bred in 1979, in the northern Lee Valley, where a small popula- tion still persists, but it seems likely that a recent expansion into Inner London stems from southwest London. Breeding was reported in Oxted in 1996 and Bushy Park in 1999 (where there were 3-4 pairs in 2002 and 4-6 pairs in 2005), and there have been breeding records from other sites including Hampton Court Park (2000), Kew Gardens and Richmond Park (both 2002). Breeding was finally confirmed in Inner London in 2008, when a pair nested unsuccessfully in Regent’s Park. Probable or confirmed breeding has since occurred at six other Inner London sites - St James’s Park, Hyde Park/Kensington Gardens, Battersea Park, Victoria Park, Burgess Park and Southwark Park; by 2011, Egyptian Geese occurred in over 18% of tetrads in the LNHS area, with breeding confirmed in 10% of tetrads (fig. 2). Other non-native wildfowl have become established since Stanley Cramp’s time. The Mandarin Duck is still increasing its range British Birds 105 • August 2012 • 433-457 439 Woodward & Arnold and now nests in the central London parks (since 2001). A breeding population of Red- crested Pochard originated from captive birds in the Royal Parks but this species is now considered self-sustaining and, from 2010, records of free-flying birds will be classified as Category C ( LBR 2008). Away from Regent’s Park and St James’s Park, where both free-flying and collection birds are present, it has also bred at Battersea Park, Kensington Gardens and Victoria Park in Inner London, and also at Richmond and Bushy Parks. But for the recent cull, the Ruddy Duck Oxyura jamaicensis would probably also have con- tinued its expansion. Several other escaped or naturalised species have bred in London (including the Bar-headed Goose at Regent’s Park, where free-flying birds were recorded during the current atlas) and could poten- tially expand their range further if permitted. The success of waterfowl is not restricted to naturalised species, however. In the mid 1920s, just Mallard Anas platyrhynchos, Tufted Duck and Moorhen Gallinula chloropus nested in Hyde Park/Kensington Gardens. The Little Grebe was an irregular breeder and the Coot did not breed until 1926 (Cramp & Teagle 1952). The Coot was initially restricted mainly to St James’s Park, where it was one of the first London birds that Stanley Cramp studied (Cramp 1947). As the case with other waterbirds, the Coot’s colonisation of Inner London may have been aided by humans. Coot eggs were apparently brought from Richmond Park and intro- duced into Moorhen nests, as the wintering Coots failed to stay for the summer (Cramp & Teagle 1952). The Great Crested and Little Grebe now breed annually in Inner London, as do the Common Pochard and Gadwall, the success of the last two species is also believed to stem from pinioned breeders. The Common Shelduck was restricted to a few localities along the Thames marshes at the time of the first atlas, but was much more common during the second, when breeding was widespread in the Lee Valley and at the southwest London reservoirs. During the current atlas, it has continued to spread and an apparently wild pair has bred in Regent’s Park (T. Duckett pers. comm.). That waterfowl have done well in London is perhaps not surprising. Defra (2011) reported that the UK population of birds of slow-flowing and standing water was 57% higher than in 1975, driven mainly by increases in Mallards, Tufted Ducks and Coots. These data include only native species, and the increase would presumably be even higher if non-natives were included (Holling et al. 2011). The London parks generally offer wildfowl a safe haven1, where they are rela- tively undisturbed and receive regular sup- plementary food from visitors. Cormorants and herons The Grey Heron was absent from Inner London when Cramp wrote his articles, but became established soon afterwards, at Regent’s Park in 1968. At this time, the only other Greater London heronry was at Walthamstow Reservoirs in the Lee Valley (c. 5 km NNE of Inner London), although the species bred at six other locations in the LNHS area during the first atlas. The Walthamstow heronry continues to be the largest in London, but has declined to around 70-80 pairs, having peaked at 138 nests in 1993. Grey Herons have since expanded their breeding range and numbers within Inner London (fig. 3) and across the LNHS area (table 1). As well as established heronries, the totals include isolated breeding attempts, such as the nest in Hyde Park in 2010 (BTO Heronries Census). The Great Cormorant Phalacrocorax carbo was a rarity in London until the 1930s, though pinioned birds produced free-flying offspring in St James’s Park in the 1930s (Sanderson 1995). The first wild breeding 1 Management of some non-native and feral wildfowl populations takes place within the London parks. This can include egg pricking and use of exclusion fencing. The species targeted are primarily introduced geese, especially Canada and Greylag Geese. The culling of adults has also occurred in the past, for example in the early 1990s (www.independent.co.uk/news/uk/whitehall-wages-war-on-canada-geese-l468476.html), but has proved controversial and we are not aware of any recent culls. The management of these species may be benefiting other species of wildfowl, through improvements in water quality and reduced competition for food and nest-sites. 440 British Birds 105 • August 2012 • 433-457 The breeding birds of Inner London Fig. 3.

Once a final shortlist had been agreed, voting members of BBRC selected this year’s winner and runners-up: each member simply ranked all the contenders in the list, and the one with the most points was the winner. A very strong shortlist this year reflects the still-increasing value of photo- graphic documentation to the record-assess- ment process. As usual, the list included a mixture of images that were instructive in terms of the identification of difficult or poorly known species and subspecies together with those that simply provided cat- egorical proof in support of a record that otherwise might not have been accepted. Photographs that made it through to the final shortlist but were not in this year’s top five included Mike Gould’s images of a puta- tive ‘Eastern’ Black Redstart Phoenicurus ochruros phoenicuroides in Kent; a ringtail harrier photographed by Martin Goodey on Scilly (submitted as a Pallid Harrier Circus macrourus but the photos provoked a useful discussion of potential hybrid features); Rob Martin’s photos of the Norfolk Rufous-tailed Robin Luscinia sibilans ; Brydon Thomason’s shots of a female Pine Bunting Emberiza leu- cocephalos in Shetland; and Alison Duncan’s images of a Lesser Kestrel Falco naumanni in Orkney. Martin Goodey’s name also appears in our top five this year, with his second shortlisted entry from Scilly being some stunning images of the Wilson’s Snipe Gallinago deli- cata at Porth Hellick, on St Mary’s, in autumn 2011. Clinching the identification of this species still requires photographic docu- mentation to ensure that the key features have been determined correctly. In cases where we need this level of detail to support the record, the quality of the images available can sometimes lead to subjective judgements (is that outermost tail feather really parallel- 259.

This enabled a critical analysis of the salient fea- tures and made the assessment relatively straightforward. The spread tail in Martin’s shot of the bird preening shows the pattern and shape of the outer tail feather perfectly and impressed all the judges. In fourth place came the Greater London/Essex (putative) Slaty-backed Gull Larus schistisagus. This bird continues several themes that were apparent in last year’s com- petition (Brit.

Second Putative ‘Eastern’ Black Redstart Phoenicurus ochruros phoenicuroides, Dungeness, Kent, November 1981. potentially a first for Britain, which is still in circulation with the Committee. The assess- ment process this time has been aided signifi- cantly by the large number of images and detailed descriptions submitted by a number of observers who encountered the bird during its sporadic appearances in the region. Several judges commented on the quality of the documentation submitted by the original finder, Dominic Mitchell. The value of the photos submitted by Dominic and others enabled us to get to grips properly with the more subtle aspects of the identifi- cation, such as the colour tones of the mantle, and this added significantly to the written descriptions. Steve Arlow’s spread- wing shot secured fourth place this year, one judge calling this image a ‘mastershot’ as it shows the ‘exact details of the secondary pattern and wing-tip (the gradation of black, the position of white ‘pearls’, the nature of the mirrors) from both below and above (and on both wings).’ In last year’s award, Steve took third place, with a different but similarly incisive series of images of a poten- tial Thayer’s Gull L. (glaucoides) thayeri that was sampling the delights of the landfills along the north shore of the Thames Estuary. In third place was Steve Gantlett’s series of photographs of the Western Sandpiper Calidris mauri at Cley, in Norfolk, from November 201 1 to January 2012. Steve’s images provided the catalyst for a range of expert opinions from across the Atlantic (and the Irish Sea), which in turn highlighted the importance of individual feather patterns for clinching the identification. Combining these with a critical assessment of structure and moult enabled this difficult identification to be settled with confidence. This shows how really high-quality images can contribute to our collective knowledge and improve under- standing of particular identification chal- lenges - one of the key criteria of this award. Sometimes, these challenges are not pursued so assiduously in areas where the species con- cerned is more abundant (and where the importance of establishing one particular identification is perhaps not so great); in some cases at least, we can potentially learn things about identification from a well- studied individual vagrant in a rarely encountered plumage which have not been apparent in that species’ normal range. Second place this year was awarded for a series of images taken over 30 years ago! Fol- lowing the debate over the identification of the potential ‘Eastern’ Black Redstarts in Kent and Northumberland in autumn 2011, Brian Cox dug out his slides of a bird trapped at Dungeness in 1981. That bird had previously been accepted by BBRC as the first record of a Black Redstart showing characters of one of the eastern races and it was recorded as such in the 1982 annual report {Brit. Birds 76: 507). However, the record was later removed 476 British Birds 105 ’August 2012 • 474-478 Brian Cox The Carl Zeiss Award 2012 from the British List by BOURC when the potential pitfalls of a hybrid Common Red- start P. phoenicurus x Black Redstart became apparent (BOU 2002). The original documen- tation submitted to the two committees was insufficient to rule out that pitfall but Brian had the foresight to realise that his images of the bird in the hand, showing the spread wing and folded wing, allowed a much more detailed assessment of the wing formula and enabled the identifica- tion to be revisited.

British Birds 105 ‘August 2012 • 474-478 477 Ian Fulton Ian Fulton Rowlands writing but so far the analysis supports the view that the record should indeed be recon- sidered, potentially as a first for Britain. This illustrates once again just how important it is that rarities are properly documented, giving us the opportunity to return to old records as our understanding of identification criteria moves on. This is particularly true of races and ‘cryptic’ species and this leads nicely on to this year’s winning images . . . A confiding Red-rumped Swallow Cecropis daurica, seen on Orkney (and photographed by Roderick Thorne) and then on Skye, proved to be even more interesting than the observers realised initially. The photographs were sufficient to determine that the same individual was involved and that the record did not appear to be of the familiar European breeding form C. d. rufula. We felt that Ian Fulton’s images from Skye provided the most informative record of the bird and enabled this individual to be assigned confidently to one of the migratory Asian races C. d. daurica or C. d. japonica. The vagrancy potential of these forms had already been identified by the Norwegians, but it was not on the radar of many British birders. However, articles in Birding World (Thorne 2011, Tveit 2011) were quick to highlight the credentials of this particular claim and, although the record’s acceptance to the British List is still pending at the time of writing, there is no doubt that this potential first would have been completely overlooked in the absence of the photographs. Those photographs have alerted us to the suite of characters that separate the eastern forms and both records committees and rarity hunters should now be aware of this likely candidate for full species status.

Birds 104: 490), in the account for the Common Pochard Aythya ferina, the authors encourage observers ‘to check lowland pools and lakes in late summer and report females with broods.’ From my own experiences, however, as summer warden at Holkham NNR in north Norfolk, where one of the county’s largest breeding populations occurs (the highest totals are 21 broods seen in both 1995 and 1999), I feel that late summer is far from the best time to search for Pochards with ducklings. At Holkham, the first broods generally hatch in mid May with a peak in numbers of newly hatched ducklings coming in the first two weeks of June. As for many species of breeding wildfowl on the site, the mortality of ducklings is high and if searches were not carried out until late summer, most of the broods would actually be missed and the breeding population would be underesti- mated considerably.

I have observed Red-necked Phalaropes Phalaropus lobatus on a number of occasions in the UK and the Middle East (and twice in the Americas) and have always been sur- prised at how little spinning they actually do. Although not recorded systematically, I was conscious that a ‘spin’ was rarely more than a couple of turns, and most of the feeding carried out while swimming comprised rapid, alternate, sideways picks at the water surface for invertebrates. This has been the case both with single birds and with large gatherings on migration when, for example, I have observed over 70,000 together on the saline lakes of northern Iran. Richard Chan- dler (pers. comm.) has also told me that he has never seen any of the three phalarope species spinning in any serious way and does not believe that it is a particularly common feeding mechanism. In the early afternoon of 6th October 2010, on a fine day with a light southwesterly wind, Simon Aspinall and I watched a juven- ile Red-necked Phalarope on Simmond’s Scrape at the Norfolk Wildlife Trust’s reserve at Cley. In contrast to our previous experi- ence, it was spinning virtually non-stop so we decided to count the number of times it spun without stopping, pausing or even hesitating. The results of 13 consecutive sets of spins were: 81, 88, 65, 206, 90, 30, 38, 11, 19, 16, 1 18, 85 and 28. We also timed a series of spins and the mean was 54 per minute. Thus although we did not time the continuous 206 spins, this series would have taken nearly four minutes. All the spins observed were in a clockwise direction (BWP states that Grey Phalarope P. fulicarius ‘spins by revolving in either direction (mostly clockwise)’, but says nothing about direction in Red-necked). Hohn (1971) stated that Red-necked Phalaropes undertake an average 46 revolu- tions per minute when spinning but does not give a range, nor does he comment as to whether spinning is the common or normal form of feeding behaviour. Could it be that 206 continuous spins is a record? Hohn also deduced that phalaropes spin to bring prey into view or within reach. A detailed study of Red-necked Phalaropes spinning in an aquarium (Obst et al. 1996) showed that the leg movements involved in spinning produce a vortex in the water below the phalarope, which brings prey items towards the surface and within reach of the bird. Each one- second spin requires 7-8 kicks of the legs and lobed toes, so the Cley phalarope would have kicked its legs over 1,500 times during its session of 206 spins! Obst et al. also pointed out that phalaropes do not spin if adequate surface prey is available. Consequently, a spinning phalarope is not only a pleasure to © British Birds 105 • August 2012 • 479-480 479 Notes watch but is a helpful ecological indicator of the state of the waterbody.

Eds Azure-winged Magpie catching an adult Barn Swallow On 21st May 2011, by the Rio Gevora (north of Badajoz, Spain), we noticed small parties of adult and fledgling Barn Swallows Hirundo rustica perched in stands of Arundo donax growing beside the river. An Azure-winged Magpie Cyanopica cyanus approached one group of swallows, flying close to the river- side vegetation so that the swallows did not notice it until it was around 4 m from them. The magpie succeeded in catching an adult Barn Swallow by grabbing the swallow’s wing with its feet - like a raptor - rather than its bill. It then landed in the reeds, where it pro- ceeded to eat the swallow. Around 20 minutes later, the same or another Azure- winged Magpie attempted a similar manoeuvre, but this time was detected earlier and all the swallows flew up and avoided capture. While nestling birds form part of the diet of Azure-winged Magpies ( BWP ), to our knowledge this is the first recorded instance of them taking apparently healthy adult birds. The closest recorded behaviour to our observations that we could find was of a captive Azure-winged Magpie attempting to catch injured small birds (Harrison 1976), although Magpies Pica pica have been recorded catching adult birds in flight (BWP).

My thanks to Dave Smallshire (a mere youngster at 60!) for suggesting the hearing test in the May issue of BB. I am still fortunate enough to be able to hear the song and calls of Gold- crests Regulus regulus well, so was not sur- prised to find that I could hear both 8 khz and 10 khz sounds (but no higher). The sonograms in BWP show that most Goldcrest vocalisations lie between 6 khz and 8 khz and therefore they are within my hearing capacity. Detecting such high-pitched calls, of course, depends partly on weather conditions and, in breezy weather, foliage noise does tend to mask such sounds - but probably for most birders, not just us older ones. As a BTO Regional Rep., 1 am acutely aware of the problems of some survey volun- teers. Indeed, a few potential volunteers in my region have declined to participate in the Breeding Bird Survey (BBS) due to their diminishing ability to perceive certain bird sounds. Of the 57 BBS squares covered in my region, a quarter have significant suitable Goldcrest habitat. A quick, and very unscien- tific, exercise to check whether all my volun- teers recorded Goldcrests in 2011 in such habitat revealed that most, including several of pensionable age, did so. In answer to Rowena Quantrill, the only female in this cat- egory recorded none! Apart from expected annual fluctuations, there seems to have been no apparent decline in the numbers of Gold- crests recorded in the few squares that have been monitored for long periods - some since 1994 - by the same individual observers (including myself). I have not rigorously analysed the regional tetrad data gathered for Bird Atlas 2007-1 1, but Goldcrests appear to have been recorded widely in all expected localities. This leads me to speculate that missing high-pitched sounds may be only a minor problem in the grand scheme of things, but I may be wrong! Norman Elkins (aged 71), 18 Scotstarvit View, Cupar, Fife KYI 5 5DX; e-mail jandnelkins@btinternet.com Richard Porter has a valid point about the effect of declining hearing in bird surveys (Brit. Birds 105: 152), but he and subsequent correspondents failed to consider another important variable in observers: eyesight. 1 can probably still hear as many Goldcrests as most people but since my eyes joined the queue for cataract removal I have increasing difficulty in seeing them, or raptors, or nests, or sorting out congregations of shore- and waterbirds. This consideration must also be important with people doing all sorts of surveys, since while the most important results should come from the same observers doing the same things repeatedly in the same places, they are less useful if they merely record their declining efficiency. While the results might be improved by the use of a telescope, this is not always practical, and anyway the method of observation would not be the same. It is difficult to know how to deal with this, since keen ageing people may either be unaware of their failing powers, or reluctant to admit them (maybe both Richard and I should have ruled ourselves out of TTVs for the Atlas?). Perhaps we should ask surveyors to give their age and state whether they can still separate House Passer domesticus and Tree Sparrows P mon- tanus at 50 paces and hear a Goldcrest. This might at least discourage those who can no longer do these things, but they remain only two among many problems with surveys - and the largest problem is often simply to find participants. W. R.

In their recent dissertation on ornithological fraud, Harrop et al. (2012) expressed the hope that more research into and fresh debates on this murky subject would follow. Must they? In a reappraisal of the 1950-57 rarities, Colin Bradshaw led an ad-hoc subcommittee of BBRC into a rational and quite brisk pub- lication (Wallace et al. 2006). A clear target was hit with (to my knowledge) only two later county queries. In sharp contrast, the paper by Harrop et al. rakes over much cold ash and yet fails to make clear which species feature in the possibly substantial number of questionable yet still accepted pre-1950 records. So I decided to probe the remaining insecurity in the records of extreme rarities before 1950. In Naylor (1996), I found 94 species that were true rarities before 1950 and still had some records from that time accepted. Within these I looked closely at the 18 species still on the British List which would have pre- sumably been highly valued in the collector/exhibitor marketplace and which remain exceptional finds today. Individually, they had attracted no more than nine reports before 1950 and had held onto no more than six acceptances since (Parkin & Knox 2010). In total, the 81 pre-1950 reports of the 18 species had been purified into 18 first records (via BOURC), eight seconds and 14 other sets of thirds or greater numbers (via BBRC, IRBC and county authorities). Nine species had been sanitised up to eight times and none of the rarest (those with only one or two surviving records) lacked the company of near-European acceptances (Mitchell & Young 1999). I detected no nest of vipers. Other similar probes of list risk could have been done by Harrop et al. Later on in the explicit traumas, I found ten accounts of alleged misconduct: one in 1946, one in 1967 and eight from 1977 to 2011. In the last period there was one admitted fraudulent protest and three exam- ples beyond reasonable doubt of strung claims. I do not recall when ‘stringing’ was fully diagnosed but I suspect that it germi- nated on a rainy day in Scilly, not later than 1971, when the late Bernard King et al. totted up some list lengths. Inadvertently, the well- meant utterance was the touch paper to increasing list comparison and competition and successive outbursts of disbelief and envy. Meanwhile the reiteration of ancient mis- behaviour adds nothing to our under- standing of current risks or the correlation of the remarkably overt strictures of the twitching fraternity. The latter has included the general (so inactionable) statement of Lee Evans, broadcast on Radio 4, that ‘13% of birders are untrustworthy’. Compared with it, the relevance of the misdemeanours of pro- fessional scientists quoted by Harrop et al. in the overwhelmingly recreational theatre of amateur bird recording is rather distant. Crucially, all parties to the issues raised by Harrop et al. should also remember that the maintenance of the British List and the com- pilation of the BBRC report requires not only the expert vigilance of the BOURC and BBRC but also the voluntary compliance of hundreds of county recorders and observers. The acceptance by observers of the disci- plines exercised by the two authorities stems entirely from consent and respect, and I wonder how those observers will react to the re-expression of multiple allegations of deceitful motives and acts. These seem to distil into five syndromes: prank, financial gain, peer pressure and resultant alterations of repute, and potentially career-advancing fraud. Among the clues for these, the com- mittees clearly pick up most on such per- ceived aberrations as serial single-observer claims, alterations in strike rate and insuffi- cient other bird finds. Yet no indication whatsoever emerges of the intelligence sources for these measures. At my last ask, the BBRC database still lacked observer names. Harrop et al. have tried to be fair in their review, admitting to some cherry-picked examples, but they have missed from the final edit of their text a clear Freudian slip: ‘to extrapolate from... suspected cases of fraud’. Were the whole record review system not vested in consent but bound by law, that kind of injudicious leap and many other infer- ences from hearsay would be inadmissible in court. 482 British Birds 105 ’August 2012 • 481-486 Letters Nobody will write it but a companion text to the recent paper 'Beams in their eyes? The risk to continuing observer consent to rarity recording disciplines from excess zeal’ would be welcome. Finally, I suggest that as the con- servation value of vagrancy science is minus- cule, the BOURC would make better use of its time if it ended its TSC’s inaction on the urgent question of which British subspecies are or are not valid taxa and so worthy of conservation concern and effort. For their sake, let us put living birds at risk First. References Harrop, A. H. j., Coilinson, J. M„ & Melling, T. 20 1 2. What the eye doesn't see: the prevalence of fraud in ornithology. Brit.

Wallace, Mount Pleasant Farm, Main Road, Anslow, Burton-on-Trent, Staffordshire DE13 9QE What the eye does see: misrepresenting the views of others, and a Freudian slip? While we agree with Harrop et al. (2012) that fraud or deception of one kind or another has occurred (and continues to occur) in ornithology, it seems worth raising the following points. Harrop et al. listed a number of letters published in British Birds to, wrongly, imply that we (and others) are ‘in denial’ that specimen fraud has taken place in the past, despite ‘accumulated’ and ‘substantial’ evidence to the contrary. However, the letters with which we were involved discussed specific records that had been rejected by the BOURC, but for which there was a complete lack of either ‘accumulated’ or ‘substantial’ evidence of sharp practice (see, in particular, Combridge et al. 2010, 2011). In this connec- tion, it is curious that when the BOURC replied to Combridge (2008) they stated that: ‘Pete Combridge and others [Chris Smout and Martin Woodcock, Brit. Birds 101: 21 1-213] who have defended the provenance of the 1908 Kermadec Petrel [Pterodroma neglecta]... are making good points’ (Brit. Birds 101: 322). The charge of being ‘in denial’ is thus not only misleading but also at variance with this statement. The fact that Harrop et al. cited our letter discussing a 191 1 record of Madeiran Storm- petrel Oceanodroma castro in Hampshire (Combridge & Wiseman 2009) as an example of fraud denial is particularly strange, as the BOURC’s reply (BB 102: 214-215) did not list fraud as one of the reasons for its rejec- tion. Unless Harrop et al. are getting them- selves into a muddle, this could suggest a Freudian slip and that the date - falling within the time period of the Hastings Rari- ties (Nicholson & Ferguson-Lees 1962) - did this particular record no favours.

Of the 487 Honey-buzzards observed there from 27th April to 31st May 2004 for which the age could be determined, they considered 18 (3.7%) to be 2CY birds, and a further 48 birds to be probably of this age class. Panuccio et al. (2004) had earlier reported around 55 2CY Honey-buzzards on migra- tion at Ustica Island (Sicily) during the first ten days of May 2002, some 3.6% of a total of 1,530 observed. Prior to this, 2CY Honey-buzzards were considered exceptionally rare in Europe. For example, Forsman & Shirihai (1997) com- mented on the difficulties of ageing 2CY Honey-buzzards accurately, discussed the ease with which adult females with juvenile- like plumage can be mistaken for 2CY birds in spring and were unaware of any sightings of this age class in the Western Palearctic documented by photos. Major raptor identi- fication works, including Clark (1999), Forsman (1999) and Gensbol (2008), pro- vided only limited information on the identi- fication of 2CY birds in spring. Panuccio et al. (2004) and Panuccio & Agostini (2006) did not specify the characters they used to determine the age of 2CY birds. Separating juvenile Honey-buzzards in their second calendar-year from some older females (particularly some 3CY birds) can be extremely difficult, particularly in spring, after a winter of plumage abrasion and bleaching in the African tropics. Over the last 25 years, I have observed several million Honey-buzzards throughout the Western Palearctic but seen no more than ten birds that I could age confidently as 2CY; an addi- tional 20 birds or so were probably also of this age class. The birds confidently aged as 2CY included five fully white-headed birds showing the following important characters: remiges and rectrices with juvenile patterning (albeit appearing bleached and abraded), in particular with the outermost (fingered) pri- maries being almost entirely dark and the secondaries almost solidly dark, with wider dark bars than most adult females; a shorter tail compared with adults in the same flock; a different wing profile, appearing rather more S-shaped; and a contrasting blackish eye- mask. The remaining five were darker but shared the same structure and wing pattern. Panuccio & Agostini (2006) referred only to the bare-part coloration of the birds they considered to be 2CY. Many adults show variable bare-part and iris colours, and it is extremely difficult to determine the age reli- ably in the field using these characters alone (Corso in prep.). When discussing the 48 probable 2CY birds, Panuccio & Agostini (2006) stated that: ‘the late timing of their passage suggests that these birds were not adults.’ In fact, it is not unusual to see adult Honey-buzzards on migration in mid to late June (Shirihai et al. 2000; Corso 2005a, b). Evidence from museum specimens and ringing recoveries Panuccio & Agostini (2006) noted that six apparent 2CY Honey-buzzards collected in Italy in spring are held in the Arrigoni Degli Oddi Ornithological Collection at the Zoo- logical Museum of Rome. During visits to this collection, I located several adult (or pos- sibly 3CY) Honey-buzzards labelled incor- rectly as 2CY. Only one, collected in Sicily and reportedly taken in spring, is aged cor- rectly as a juvenile. However, this bird is in fresh plumage, with no sign of wear, bleaching or moult; it seems likely that it was labelled incorrectly and was actually collected in autumn. In addition, notes by Del Nero, the taxidermist who prepared the above specimens, indicate that some birds, most probably younger adults (3CY+), can show variable bare-part colours, reinforcing the point that it is extremely difficult to use these characters to age Honey-buzzards confi- dently. Ears Svensson (in litt.) has commented that only three birds with Swedish rings have been found in the spring of their second cal- endar-year, one each in Sweden, Germany and Italy. Of these, the Italian record con- cerns a bird ringed in Sweden in summer 1925 and recovered in Italy on 26th April 1926. There is some uncertainty about the ringing and recovery data of the German 484 British Birds 105 'August 2012 • 481-486 Letters record, while the Swedish recovery concerned a ring found with the decomposed remains of the bird, so it is possible that this bird could have died during its first autumn. Svensson also described a record of a Honey- buzzard recovered in April of its second cal- endar-year in Norway. This is an extremely early date for this species to reach northern Europe and this bird may have spent the winter in Europe. Indeed, there are several documented records of Honey-buzzards win- tering in Italy and elsewhere in the Western Palearctic, the majority being juveniles that have interrupted their southbound migration for some reason (e.g. Grussu & Azzolini 1997, Grussu & Corso 1997, Grussu et al. 1998, Corso et al. 2000, Corso 2005b and Ruggieri & Nicoli 2009). Discussion If 2CY Honey-buzzards are reaching Europe regularly in spring, it is likely that they will pass through migration bottlenecks such as Eilat. However, this appears not to be the case. Shirihai et al. (2000) noted a late-spring passage of non-adult Honey-buzzards in Israel, some of them considered to be 2CY birds, but those findings have now been reconsidered; Shirihai (in litt.) commented that, in the 1980s and 1990s, they considered some spring birds to be 2CY or 2CY/3CY, but subsequent observations have failed to reveal any 2CY birds and as a result he now con- siders that some of the earlier birds were aged incorrectly. It is certainly possible that small numbers of 2CY Honey-buzzards reach Europe in spring, but the evidence suggests overwhelm- ingly that they appear much less frequently than reported by Panuccio et al. (2004) and Panuccio & Agostini (2006). The importance of establishing the pattern of the fingered outer primaries, the key character for ageing Honey-buzzards reliably (Forsman & Shir- ihai 1997; Forsman 1999), cannot be over- stressed and any claim of 2CY Honey- buzzards in spring should be documented carefully, incorporating some or all of the characters described in the third paragraph above. Other reported ageing characters, including bare-part and iris colour, remain both highly variable and difficult to deter- mine accurately under field conditions.

At the time of our observations, the only information on the characters of 2CY Honey-buzzard was given by Forsman (1999). In addition to plumage features, Forsman stated that: ‘Captive birds in 2nd cy summer had a yellow cere with darker spots and the eyes were turning yellow, appearing pale from a distance... Iris already dull yellow and cere showing dark spots by 2nd cy Feb’. Accordingly, we considered that only individuals showing a yellow cere, dark iris and juvenile plumage characters (in partic- ular, from below, a largely black wing-tip with pale primary bases, contrasting with largely dark secondaries with just the bases paler) were 2CY birds, in order to keep our data as conservative as possible. We chose a watchpoint from which it was possible to observe a good sample of raptors at close range and, since juvenile birds are expected to migrate later than adults, we decided to continue the fieldwork until the end of May, later than other monitoring projects in the central Mediterranean area (Gustin et al. 2005). Since we aged birds only when it was possible to observe both cere and iris, only 4.2% of Honey-buzzards counted in spring 2004 were considered in the analysis. Further data were provided by two birds killed by poachers at the Strait of Messina in spring 2004 and by those held in the Zoolog- ical Museum of Rome. As at the Strait of Messina, we considered both the plumage and the colour of the cere/iris. Since the iris had been lost and the cere is often damaged in museum specimens, we checked the notes of the taxidermist. In particular, we did not use the taxidermist’s determination of age but simply their description of iris and cere colour. Corso (above) sheds doubts on the number of 2CY Honey-buzzards (18 individ- uals) that we reported at the Strait of Messina. However, it is not unexpected that limited numbers of 2CY long-distance- migrant raptors reach the Mediterranean and Europe, as in the case of Short-toed Eagles Circaetus gallicus (Premuda et al. 2010; Mellone et al. 2011). Moreover, in the case of the Honey-buzzard, it is well known that a higher proportion of juveniles has been reported along the central Mediterranean flyway than along the eastern and western detour routes during autumn migration (Agostini & Logozzo 1995; Schmid 2000; Hake et al. 2003). Unlike Corso, we suggest that a higher proportion of 2CY birds migrate through this Mediterranean area in spring too, retracing the track of their first southbound migration. We hope that, as characters for identifying 2CY Honey-buz- zards continue to develop, it will be possible to verify further that up to 3% of the Honey- buzzards migrating through the central Mediterranean in spring are 2CY birds.

And when it’s written by Tim Birkhead, you sit up and take note. Written in Birkhead’s deceptively easy style, this delightful little book is a wander through the avian senses, with chapters on seeing, hearing, touch, taste, smell, magnetics and (perhaps a little unex- pectedly) emotion. He draws together a mass of information - historical, anecdotal, anatomical, observational and experimental, interwoven with entertaining little personal reminiscences - and uses this to analyse and describe how the avian brain interacts with the outside world. This is effec- tively a book on avian behavioural physiology - a new branch of science? If that sounds dull, then it is my literary weakness, for this is a fascinating read. There is some stuff that ‘everyone’ knows, but lots more that is new and beautifully described. I found the chapter on magnetic sense both illuminating and frustrating. He presents a suc- cinct review of the history of experimental bird migration showing how (at least some) birds must use the earth’s magnetic field to orientate and nav- igate. Yet, a few years ago, hardly anyone believed that birds could sense this at all. Frustratingly, many links in the story remain to be discovered: maybe that’s why this chapter is the shortest! How exactly do birds like Bar-tailed Godwits Limosa lapponica find their way non-stop across the Pacific from Alaska to New Zealand, or Manx Shearwaters Puffinus puffinus navigate from Skomer and Skokholm to Argentina? Are they really using magnetism? How important is mag- netite in this physiology? How does magnetic sen- sitivity interact with vision? If this chapter doesn’t fire up undergraduate ornithologists to study bird migration, then I despair! On the subject of emotion, Birkhead spends a good deal of space describing the neurobiology and endocrinology of emotion in mammals generally and humans in particular. Since birds have essen- tially the same hormones, maybe they can also feel affection, fear, hope, despair? He doesn’t climb down off the fence here - we just don’t know. That’s what makes this book so engaging: there is so much that we don’t know and, unlike many authors, he doesn’t pretend that it is otherwise. Oh yes, and ‘Buggered’ is the word he uses to describe the bird fauna of New Zealand. Not sure it has a lot to do with avian senses, but it’s spot on. My own first visit to that country began with a drive north from Auckland Airport: it was two hours before I saw a non-European bird - and that was a myna (Sturnidae). This is an excellent book: how I wish I could write like that!

Moving east, the popular Abuko reserve is dealt with in some detail. Then moving past Pirang the journey takes in Ginack Island, and then upriver on a solar-powered boat to Tendaba, Janjanbureh and MacCarthy Island. In total 30 sites are visited. The habitat and surroundings are shown for each site, and Dave is often in front of the camera giving his own perspective on the best way to see the most birds. A new development is informal interviews with the guides and owners of the bird lodges. There is plenty of great bird footage and almost 170 species are featured, including targets such as Egyptian Plover Pluvianus aegyptius, Black-crowned Crane Balearica pavonina and African Finfoot Podica sene- galensis. A gallery of photos by Steve Garvie and Modou Colley is also included on the DVD. As always the booklet describing the sites is detailed and enormously helpful, with clear maps and precise GPS readings for locations. You could simply buy this on its own, but the DVD brings it all to life. I made my first trip to The Gambia almost 30 years ago and it is good to see that the birding oppor- tunities are perhaps better now than they were then. Despite the fact that I’ve made two further trips, I still discovered new locations with this DVD and booklet - which is probably the best test for any such product. Keith Betton mmm Birds of Aruba, Curasao and Bonaire Birds of Aruba, Curasao and Bonaire By Bart de Boer, Eric Newton and Robin Restall Helm, 2012 Pbk, 192pp, 71 colour plates ISBN 978-1-4081-3727-7 Subbuteo code M21044 £24.99 BB Bookshop price £22.49 Known until 2010 as the Netherlands Antilles, these islands made up an autono- mous Caribbean country which was part of the Netherlands. Often referred to as ‘the ABC islands’ they are semi-arid, with distinct dry and rainy seasons, and lie off the north coast of Venezuela in the southern part of the Caribbean Sea. The bird fauna of the islands is considered to be South American but there is also a strong West Indian element, most marked in Bonaire. The islands have around 70 breeding species and do not support any endemics, but at least 16 local subspecies have been described, including four exclu- sively from Bonaire and two from each of Curasao and Aruba. Of particular interest are well-differenti- ated forms of White-tailed Nightjar Caprimulgus cayennensis , Brown-throated Parakeet Aratinga per- tinax and Grasshopper Sparrow Ammodramus savannarutn. The only threatened species on the islands is the Yellow-shouldered Amazon Amazona barbadensis, which is restricted to Bonaire. In 1983, Karel Voous produced an English version of his Birds of the Netherlands Antilles but, despite an extensive text, the book was inadequately illustrated. So this is the first comprehensive book on the birds of the region. It is laid out in typical field-guide style with annotated colour plates on the right-hand pages, featuring around five species and text on the opposite page. Among the 71 colour plates there are almost 1,000 images of 285 species. The majority of Robin Restall’s illustrations have been taken directly from his Birds of Northern South America and the smaller Birds of Trinidad and Tobago , although others have been newly created. The plates are over-colourful in places and the pro- portions of some of the birds (particularly the waders) feel out of proportion. Some migrants from North America are illustrated only in non-breeding plumage, since these birds will have already moulted by the time they arrive on the islands in the autumn. The text is concise and covers the main identi- fication topics, including plumage features, voice, habitat and status. An introductory section dis- cusses the history, geography and biodiversity of the islands, including notes on the best spots to go birding. Alternative names are given in Dutch and Papiamento (the local creole language). Given the small size of the islands there are no maps, but a checklist indicates which islands each species has been recorded from. The status texts emphasise how the majority of species in this book are, in fact, rare visitors to these islands, and your likely trip list will comprise a meagre 70-80 species. While these islands are popular with American tourists, and divers in particular, there is relatively little to attract the keen birder. However, if you do decide to visit, this is the guide to take.

Bordering Poland, it surrounds the national capital of Berlin, which is also a federal state in its own right. The combined surface area of over 30,000 km2 means that it is about 50% larger than Wales but is almost totally flat. It has a rich diversity of birds, some of which are rare in the UK and much of Europe. With over 3,000 lakes, this is a region where large numbers of wintering geese can be found, and in the right months you can connect with thousands of migrating Common Cranes Grus grus as well. In all seasons there are plenty of raptors, and this is where you can see the last remaining population of the Great Bustard Otis tarda in northern Europe. Other local specialities include Lesser Spotted Eagle Aquila pomarina, Little Crake Porzana parva , River Warbler Locustella fluviatilis, Thrush Nightingale Luscinia luscinia. Red-breasted Flycatcher Ficedula parva and Common Rosefmch Carpodacus erythrinus. With a wealth of cheap flights from the UK to both of Berlin’s airports, and a journey time of around two hours, it is surprising that more birders do not visit the area. As Roger White suggests, the reason is probably the dearth of information in English that could direct birders to the best loca- tions. This guide details 110 sites and divides them into eight regions, including 31 in Berlin itself. For each region there are numerous maps, each of which covers several sites. I did find myself getting slightly confused by the use of numbers to indicate options within each site (so sites 1 and 2 appear on map 1, but are numbered 1 to 5, while site 3 appears on map 2 but is numbered 1 and 2). So I do recom- mend getting to know this book before you arrive in Germany, perhaps using Google Earth to allow you to ‘explore’ it in some detail. Personally, I like to work out GPS co-ordinates for parking spots and secluded locations, and had these been included in the book I think it would have helped a great deal. Hints about accommodation and useful web- sites are given for each region, together with details of access by car or public transport. There are many photographs showing the habitats and main features. A list of about 250 regular species is pro- vided with English, German and scientific names. The main index allows quick reference to find sites for your target species. This is a nicely produced book, which will certainly help anyone who decides to watch birds in this surprisingly rich area of eastern Germany.

Not surprisingly (for, among other things, he is both a poet and a literary critic), they are carefully crafted and well-written pieces. There is also something delightfully old-fashioned about them - reflecting tire author, who, I think, will always be a birdwatcher rather than a birder. This a collection of these weekly offerings, arranged by the months of the year. Their style will not be to everyone’s taste, but there is no mis- taking Derwent May’s enthusiasm for his subject - nor the depth of his knowledge. His little stories are generally spot on, too: I know from personal experience how thoroughly he does his homework. It is surely a good thing that collections like this are published. It is a shame, though, that not many copies are likely to be sold.

These latest chicks are part of the emergency conservation breeding mission to insure the species against imminent extinction in the wild. As we went to press, four further eggs were expected to hatch, which would bring the total flock size at Slimbridge to 30. The size of the flock is critical for triggering breeding behaviour in these extraordinary waders, which reproduce at two years old. The birds were hatched from eggs taken from the tiny remaining wild population which breeds on the sub-Arctic tundra in the Russian Far East. They were flown by heli- copter and plane on a week-long journey via Anadyr, Moscow and Eleathrow before arriving at Slimbridge. WWT Head of Con- servation Breeding, Nigel Jarrett, travelled with the eggs and is overseeing the care of the tiny chicks, which hatched the size of bumble- bees. He said: ‘We hatched the first of our conservation breeding flock on the tundra last year and brought them back when full grown. With all we learned then, it made sense to transport them as eggs this year and the huge privilege for the UK is to have these amazing little chicks hatch here for the first time.’ The dramatic decline in Spoon-billed Sandpiper numbers was first observed in 2000. Now fewer than 100 pairs are thought to remain. Christoph Zockler led the expedi- tion this summer to Meinypil’gino, the main breeding site, on behalf of Birds Russia. He said: ‘The number of pairs returning to Meinypil’gino dropped again this year, to fewer than ten pairs, [reflecting] the wide- ranging conservation problems along the birds’ flyway. We did have some good news, though. With more volunteer fieldworkers this year, we were able to search more remote areas away from the village for the first time and we found five further pairs.’ Tim Stowe, Director of International Opera- tions at the RSPB, said: ‘This is a great example of organisations, experts and individuals from around the world working together to save an animal from extinction. All elements of this project - from our work with subsistence hunters in Myanmar and Bangladesh, to efforts in Asia, where the birds’ habitat is severely under threat, and the captive breeding programme here in the UK - will make sure future genera- tions won’t have to rely on pictures of a quirky little bird that could have been saved if only we hadn’t let them down.’ Debbie Pain, Director of Con- servation at WWT, said: ‘The level of support for the Spoon-billed Sandpiper has been phenomenal. But it is expensive work and we are still £50,000 short just for this year. I urge anyone who is taken by the Spoon-billed Sandpiper to make a donation, however small.’ Visit www.saving-spoon-billed- sandpiper.com or search for the hashtag #sbs2012ex on twitter. 266. A one-day-old Spoon-billed Sandpiper Eurynorhynchus pygmeus chick. 490 British Birds 105 'August 2012 • 490-493 News and comment Gamekeeper fined for trapping and starving Buzzard Defra may have backed away from its controversial trial of Common Buzzard Buteo buteo ‘control’ {Brit. Birds 105: 424—425), but one gamekeeper has been caught trying to implement his own. RSPB Scotland has welcomed the conviction of a Perthshire gamekeeper who allowed a Buzzard to starve to death in a trap. The case began when Tayside Police responded to a report from a hillwalker that three crow traps had been found on the Glen Lyon Estate in Perth & Kinross containing a dead Buzzard, a dead Eurasian Sparrowhawk Accipiter nisus and two Common Chaffinches Fringilla coelebs, respectively. Jonathan Smith Graham, a gamekeeper on the estate, pleaded guilty at Perth Sheriff Court to using a crow trap in which a Buzzard was trapped and starved to death. His ‘not guilty’ plea was accepted for the two other charges. Sheriff McCreadie said: ‘This case involved a dereliction of duty to wild birds. You did not act as a reasonably competent gamekeeper.’ He compared the case to that of a drink-driving offence in which there is a mandatory disqualification, where conviction ‘can lead to consequences including loss of employment.’ He went on to say: ‘I am satisfied that this is a case where a fine is appropriate, not only for you, but to discourage others.’ Graham was fined £450 but, perhaps more importantly, he has now been banned from operating a crow cage trap for five years. Speaking after the court case, Ian Thomson, RSPB Scotland’s Head of Investigations, said: ‘We welcome the conviction of Mr Graham and the strong comments made by the Sheriff. This latest case illustrates, yet again, the lax approach taken by some gamekeepers to following the licence conditions laid out by the Scottish Government. The use of these licences is a privilege, and with this comes responsibility. Mr Smith clearly did not take his responsibilities seriously and has now lost that right.’ Golden Eagle found poisoned Police are appealing for information after a Golden Eagle Aquila chrysaetos was found dead near Morar, Lochaber (Highland) in March. A post- mortem showed that the eagle had been poisoned with banned pesticides. This is the third known eagle poisoning incident in the area over the last ten years, with two White-tailed Eagles Haliaeetus albicilla being the previous victims. Ian Thomson, RSPB Scotland, said: ‘Despite the hard work being done by the police and partner agencies, some individuals continue to disregard the law, and public opinion, by killing protected birds of prey. Sadly, this is just the latest in a long list of Golden Eagles found poisoned over the last few years, and that only represents those actually discovered. Who knows how many of these magnificent birds are killed but never found? We condemn the actions of those who continue to kill Scotland’s birds of prey, and hope that anyone with information related to this or other wildlife crimes will step up and pass this to the police or contact Crimestoppers.’ The eagle had been fitted with a satellite transmitter in 2010 prior to fledging from a nest in a habitat management area created by Scottish Power Renewables beside Beinn an Tuirc windfarm on the Kintyre peninsula. Golden Jubilee of nesting survey Next year will mark the 50th anniversary of the publication of Rachel Carson’s Silent Spring in the UK, one year after it was first published in the USA. What is perhaps less well known is that it also marks the 50th anniversary of an unusual bird survey carried out by then BB Editor James Ferguson-Lees, in company with fellow naturalists Dennis Elliott and Bruce Campbell. Their aim? To see how many nesting species they could find at the Southill Park Estate in Bedfordshire. This 1963 endeavour was itself undertaken to mark the 60th anniversary of a similar outing in 1903 involving Jannion Steele- Elliott (uncle of Dennis) and Ronald Bruce Campbell (father of Bruce). On that turn-of-century occasion the pair found nests with eggs of 27 different species. This was thought to be ‘a feat which can have few parallels in British field ornithology’. As it turned out, the sixties group nearly emulated them - but not quite. Having discovered the story of this repeated survey in an old copy of The Bedfordshire Naturalist (the tale was also republished as a chapter in the book Best Days with British Birds , in 1989), Conor Jameson thought that it would be remiss not to attempt to repeat the project, 50 years on. Barry Nightingale - who carries out British Birds 105 • August 2012 • 490-493 491 News and comment WeBS surveys at the park’s extensive lake - sought permission (duly and kindly granted) from the Southill Estate to carry out a recce in June 2012. Barry and Richard Bashford will again join Conor for the full survey in early June next year, the results of which will be written up for BB. ‘It will provide a unique opportunity to gain a snapshot of how things have changed across the last century or so, and since Silent Spring, and the Edwardian era, on one carefully managed and very scenically appealing lowland English estate, with a range of interesting habitats,’ said Conor. ‘There will be a bit less emphasis on finding the actual nests,’ added Richard Bashford. ‘It’s not just that we may have lost some of those old nest-finding skills of our forebears, but times of course have changed. We’ll settle for ‘strong evidence of breeding’ - and see how we go. We found quite a few in five hours this time, and will have longer to look on the big day, next year.’ Black-winged Stilts attempt to breed in Somerset Yet another long-legged bird has found Somerset to its liking, following recent breeding success in the county for Great White Egret Egretta alba, Cattle Egret Bubulcus ibis and Little Bittern Ixobrychus minutus (see Brit. Birds 105: 423-424). This spring saw a noticeable influx of Black- winged Stilts Himantopus himantopus into Britain. Although they turned up in most of the surrounding counties, they seemed to be actively avoiding Somerset, where the last twitchable bird was in May 1980, at Steart. Then, on 2nd June, local birder Roger Musgrove hit the jackpot on Curry Moor, which (unusually for the time of year) was flooded after prolonged heavy rain. As other local birders gathered on site, one Black-winged Stilt quickly became three, and it also became apparent that something even more remarkable was happening - two of the birds were a pair, and they were nesting! The RSPB was informed and arrangements put in place for 24-hour monitoring of the site. Alas, in worsening weather, the birds stopped sitting - less than a week after the nest was discovered, it had been deserted. In fact, the attempt may have been doomed anyway, since the remaining floodwater was low in oxygen and it is doubtful that there would have been enough food available on site to support the chicks. Brian Hill, President of Somerset Ornitho- logical Society, said: ‘In a year when the UK’s first pair of Great White Egrets has fledged three young in Somerset, it would have been another great coup if the stilts had also been successful, but it was not to be. Many thanks, though, to the farmers and landowners of Curry Moor who reacted so positively and sympathetically to the news of the attempt despite the difficult circumstances.’ ( Contributed by Julian Thomas) Green shoots of recovery for House Sparrows? The House Sparrow Passer domesticus has been in long-term decline in the UK and BTO surveys show that the number of House Sparrows using garden feeders in winter has fallen by two-thirds since the early 1970s. The middle of the last decade saw a particularly sudden decrease, which coincided with a large outbreak of the disease trichomonosis in Greenfinches Chloris chloris and Chaffinches. It is possible that trichomonosis might also have had an impact on House Sparrows, although further analysis is required to establish a link. Since the lows of 2006 and 2007, however, the numbers of House Sparrows in gardens have rallied and are now approaching a six-year high. This recovery is fragile, however, and English House Sparrows in particular are in need of some TLC. Since 1995, when the year-round BTO Garden BirdWatch survey started, declines of House Sparrows in English gardens have been much steeper than those in Scottish or Welsh gardens. On average, almost one in four English gardens has lost its House Sparrows since 1995, compared with fewer than one in ten in both Scot- land and Wales. Early indications suggest that Irish House Sparrows are also faring better than those in England. A new House Sparrow factsheet is available free from the BTO (just e-mail gbw@bto.org). Cuckoo update Since last month’s issue, there has been plenty to report on the Common Cuckoo Cuculus canorus sponsored by British Birds, part of the BTO Cuckoo project. BB was the first of the Scottish Cuckoos to leave the UK, on 18th June, arriving in the Netherlands after an unusually long sea crossing. From the Netherlands, he passed through Germany and the Czech Republic and, as we went to press, he had arrived in northern Italy. Follow his progress, and that of the other satel- lite-tagged Cuckoos, at www.bto.org 492 British Birds 105 • August 2012 • 490-493 Terry Whittaker/FLPA News and comment Cornish Choughs are Irish The Red-billed Chough Pyrrhocorax pyrrhocorax stands proud on the Cornish coat of arms but the species became extinct in the Duchy in 1947, denuding Cornwall of one of its most charismatic birds and cultural symbols. That was until three Choughs of unknown origin appeared in Cornwall in 2001 and founded a new breeding population, restoring the ‘Cornish Chough’ to its historical home and causing great excitement among birdwatchers and conservationists alike. (See the 267. Red-billed Chough Pyrrhocorax pyrrhocorax, Saltee, Co. Wexford; it now appears that Choughs from Ireland may be the source of the re-establishing population in Cornwall. paper by Ian Johnstone et al. in the August 201 1 issue of BB for a fuller account of the Chough’s return to Cornwall; Brit. Birds 104: 416-431.) But where did the three pioneer Choughs come from? Until now, it had been assumed that they had come from Chough populations in Wales or Brittany. But now, genetic analysis suggests that they came from even farther afield - from Ireland, in fact. Scientists from the University of Aberdeen collected moulted feathers from the Cornish Choughs, and from Choughs in other populations across Europe. They extracted DNA from the feathers, and compared the DNA sequences of the new Cornish Choughs with those of Choughs living elsewhere. By far the best match to the Cornish Choughs came from birds in Ireland, suggesting an unexpected Celtic origin for the new Cornish birds. Dr Jane Reid, Royal Society University Research Fellow at the University, said: ‘We would never have known the origin of the new Cornish Choughs without the DNA analysis - we didn’t guess that they had come from Ireland.’ The RSPB’s Claire Mucklow, one of the co- authors of the BB paper referred to above, added: ‘We assumed that those intrepid colonists would have come from closer populations; how wonderful that they have turned out to be Irish! The return of Choughs to Cornwall has been very significant, not just in terms of conservation but in terms of Cornwall’s cultural heritage.’ The new Cornish Chough population is now going from strength to strength and five pairs bred successfully in 2012. The future success of the population is being ensured by conservation organisations and farmers, who are working to provide suitable habitat, and by volunteers, who provide round-the-clock surveillance of nests. With recent sightings of colour-ringed Welsh Choughs in north Devon, there is potential for a merging of Celtic Chough diversity in southwest England, which researchers say can only be positive for the future prospects of this terrific species.
