With the exception of a few west-midland and northern counties the harvest mouse has been recorded in a wide variety of habitats over most of England, including forty- one of the forty-seven 10 km. saueres which fie wholly or partially within the county of Wiltshire. The vast majority of records has been based not on the sighting of the animal but on the incid- ence of distinctive summer nests, which are built in the stalk zane of vegetation for breeding and shelter. Apart from being imporiant as a species indicator, these nests provide a valuable source of information on the breeding iiabits He life styie of the harvest mouse. In this paper, habitat selection and the general nest ecology of the harvest mouse are examined. with special reference to the sites where the snecies has been shown to occur in Wiltshire. GENERAL REVIEW The genus Micromys contains only one species, M. minutus (Pallas), and this 1s restricted almost entirely to the central band of the Pataearctic Region with Britain forming the western extremity of its range. Several sub-species are known to exist. ihe only one present in Britain and in most of western Europe being A/.m.Sericiaus (Hermann). in Barrett-Hamilton & Hinton (1910- 21), although acknowledging the lack of fossil records relating to Micromys, felt that organisational features of the genus indicated that it evolved from eastern, Apodemus-like, ancestors and spread to western Europe only in gaan avely recent tires. Frank (1957) claimed that pygmy growth was almost certainly the first evolution- ary step towards the colonisation of the ecological niche of the stalk zone by these rodents. He postulated that all cther behaviour traits now shown by Micromys were secondary acquisitions gained as the species began to take advantage of its new environment. It is said that Micromys, because of its diminutive size, is now too weak to burrow d leeply into the earth and so can no longer lead a typical murid existence on the ground (Piechocks, 1958). Instead. it is well suited to life in dense vegetation and is aided in this respect by possessing a semi-prehensile car in conjunction with the hind feel, this tail is used for holding the animal on a stem thereby leaving the front paws free for feeding and nest construction. There are, however, two main limiting factors influencing the suitability of the stalk zone habitat. First, the herbage must be dense enough in summer to provide the necessary materials for the construction and, more importantly, for the sapport of a protective nest to house the young mice which are born blind, naked and helpless. Second, the ground vegetation cover of the site in winter must be of sufficient thickness to offer shelter and cover. An extremely large number of wild plant species falls within the limits of suitability for Micromys colonisation. Many species of Gramineae and Cyperaceae are used in Japan (Shir- aishi, 1969) and, in Russia, Calamagrostis and Phragmites are particulariy favoured (Sleptsoy, 1948). Barrett-Hamilton & Hinton (1910-21) list a wide variety of species used in Britain, among them Prunus spinosa and Clematis yitalba. Many crops cultivated by man provide Micromys with ideal conditions; the ricefields of Europe and the oatfields of Germany have often been heavliy infested with the species (Piechocki, 1958). Sometimes Micromys are carried with the crops into storage where they are provided with winter shelter which is relatively predator free and rich in food supplies. In fact, so favour- able are some of these sites that it has been known for Microniys to multiply to such an extent that their ravages cause serious economic damage. Thus thare are records of considerable — damage to stored wheat, rice, millet and other crops awaiting threshing in parts of Russia (Elton, 1942, p.45; Sleptsov, 1948; and Smirnoy, 1959). Ps Bane The extent of the relationship between Micromys and the arable habitat in Britain is not clear. The species apparently suffered a marked decline in the century or so foliowing its simul- taneous but independent discovery in England by Gilbert White and Montagu. Millais (1904-6) was one of the first to attribute this decline to mass destruction of breeding nests following the introduction of the close cutting reaping machine. However, E. J. T. Collins’ review of har-- vesting techniques from 1800 to the present day indicates that although the mechanical reaper was first invented in the late 1820's it was only gradually adopted as a harvesting tool in this country. Even by 1871 only about 25 per cent of Britain’s corn area was cut by mechanical means (Collins, 1969). It is likely that before this other factors were influencing the suitability of the cornfield as a Micromys habitat, particularly the introduction of mechanical drilling which replaced hand sowing in the early nineteenth century. Clark (1973) has drawn attention to the fact that the old method of sowing corn by hand tended to produce clumps of plats ideally suited to the construction of Micromys nests by the stripping and weaving of living Itaves. More recently some writers have maintained that the combine harvester, like the mechanical reaper, has had a disastrous effect on Micromys numbers (see for example Campbell, 1951; Matthews, 1952; and Hosking, 1972). In addition chemical sprays have almost eradic- ated the wild plants which once added to the physical bulk of the cornfield. Thus, in theory, the arable habitat should gradually have become less inviting to Micromys. Certainly, in some districts where the species is abundant, breeding can be shown to be taking place in the fringe vegetation surrounding large arable fields but never in the standing corn itself. However, the Mammal Society’s survey has shown that in other districts cornfields support vast breeding colonies of Micromys. This local variation in the use of the arable habitat is probably related to the extent of the fringe vegetation surrounding the fields. Where this fringe vegetation is extensive, and where it provides suitable stalk zone support for nests, it offers a more stable environment than the arable crop and thus is preferentially colonised. Where the fringe veget- ation is sparse, population dynamics probably demand the use of the crop for breeding purposes. Throughout the entire range of Micromys, however, it seems that the wetland habitat is of the utmost importance to the species. Damp water meadows are “specially favoured”’ in Germany (Piechocki, 1958) and in Czechoslovakia the “most favoured conditions for living” are found in the vicinity of drainage channels (Kminiak, 1968). Similarly riverside meadows are well colonised both in Poland (Kubik, 1952) and in Russia (Sleptsov, 1948). In Britain, Teagle (1964) has drawn attention to the importance of the wetland habitat in the London area and Clark (1973) has suggested that Micormys “probably thrived best in primeval times as it does today in the marginal habitats between wet and dry land along river valleys and in marshes.’ The vegetation of the wetland habitat is-characterised by the more robust types of Gram- ineae and Cyperaceae suchas Phragmites communis and Carex spp. which provide the strong tall stems so vital to the support of the Micromys breeding nest. It is in these ideal habitats, where nests may be suspended in the vegetation up to a height of 150cm., that Micromys truly fulfils its breeding potential. Where tall vegetation is absent, as is often the case in areas of coarse meadow, pasture and roadside grassland characterised by Dactylis glomerata and Deschampsia cespitosa, nests are often built a few cm. aboye ground but are seldom present in any great numbers because here Micromys is in direct competition for food and nesting sites with other larger surface dwelling murids. Nests are usually composed of the vegetation in which they are suspended. Piechocki (1958) has pointed out that members of the family Gramineae are characterised by unbranched leaves which have parallel equally spaced veins running almost to the point of each blade. Such leaves are easily separated and shredded into strips by the pulling and tearing action of Micromys incisors. The leaf is thus split into several lengths of almost equal width which aatomatically complicate themselves into spirals and in this way the leaves of living plants can be incorporated into the outer structure of the nest. Barrett-Hamilton & Hinton mention that Douglas English once found 250 split lengths in a single Micromys nest and he estimated that at least 100 com- plete leaves had been utilised. There appears to be some geographical variation in basic nest structure throughout the range of Micromys. In Japan, Shiraishi (1969) has classified six main types according to shape and construction. These he designates as cocoon typ, lantern type, dish type, “binded” type, bird’s nest type and pot type, with the “‘binded”* type being the most numerous. Sleptsoy (1948) 4 Pa ah | in Russia distinguished between loosely made nests situated on the ground and more substantial structures suspended in vegetation, but attributed most variation in shape to deformation caused by the growing family of mice. This explanation seems to account for the variation in shape of the British nests which are usually compact, spherical, closely woven structures corresponding most closely. to the Japanese “binded” type. In Britain they range in diameter from 3 to 10 cm. and generally increase in physical butk the higher they are suspended in vegetation to counteract increased vulnerability to adverse environmental conditions. In terms of composition, Shiraishi (1969) has shown that nests built by the Japanese sub- species M.m. japonicus generally consist of 4 layers—en outer layer, middie layer, inner layer and a bed, with the last usually made from gnawed and torn leaves, flowers and seed heads. Sleptsov (1948) found the nests constructed by the Russian and cast European subspecies*W.n1. ussuricus to be composed of an outer layer of entire stalks and icaves with an inner layer of the same material carefully split longitudinally and tightly compacted. Analysis by the authors of nests constructed by the British subspecies (M/.m. soricinus) indicates that some consist of only a single layer of longitudinally split leaves with occasional seed or flower heads incorpor- ated and that other, usually bulkier, nests have in addition a discernable inner lining of finely chewed leaves and seed heads. Generally speaking, those nests with a distinct inner lining are used for breeding whereas those without the lining are probably only used as summer shelters. In Britain the main breeding season of Micromys would appear to be from July to September. It has been suggested (see for example Knight, 1963; and Trout, 1974) that some breeding of Micromys may take piace in the spring or early summer months. Hedgerows, hay ticks and straw stacks are thought to be the sites cf such breeding. However, the authors have found no evidence of early breeding in central southern England, Hosking (1972), who has studied extensively the habits of Mieromys in the vicinity of his Devonshire farm, found no evidence of breeding in ricks. The work of Rowe (1958) adds further support to these observat- ions; in March 1957 he examined 119 Micromys obtained during the threshing of 7 ricks on a Hampshire farm; by looking at the cauda epididymidis with a hand lens and checking his obser- vations with a microscopic examination of a stained smear of the epididymus he was able to establish that, whereas almost half the males were fecund, all the females were in a non-breeding condition. Kubik (1952) studied the natural breeding of M.m.soricinus in a Polish National Park. Very exceptionally he recorded young Mieromys in late April but gives late May as the date for the onset of the normal breeding season. In climatic terms this would be equivalent to late June in central southern England (Kenbrew, 1953, pp 378-388; and Austin & Haurwitz, 1944, pp 257-262). At this time of year the Micromys population would be atits annual low and thus breeding would be numerically slight at first. With early season young becoming sexually mature after about 40 days this would, however, permit the young from the first and second litters to contribute to a “rapid and geometrically progressing revival of the population which reaches its numerical maximum in autumn” (Kubik, 1952). From the determination of age by tooth wear of Micromys following this breeding pattern, Kubik estimated ihe maximum life span of the mice to be 16 to 18 months. Ns HABITAT SELECTION AND NEST ECOLOGY IN WILTSHIRE George Montagu wrote of the harvest mouse “The discovery of this least of British quadru- peds was made by the revd. Mr. White in Hampshire and communicated to Mr. Pennant in the year 1767. It is however by no means peculiar to that county and | doubt not but they are equally discovered over all the southern provences, at least in the neighbourhood of the Devizes I found them in great abundance and remember to have noticed them full twenty years ago when a boy at Urchfont School....’ (Montagu, c 1785). Almost 200 years later harvest mice are “equally discovered” over southern England (although not perhaps in quite the same abund- ance) and the current distribution map of the species in Wiltshire shows a concentration of Micromys records in the neighbourhood of Devizes. Wiltshire is divided into two main geological areas: The north, north-west and the extreme. west, comprising about two-fifths of the county, are based upjon the Jurassic formation and the remaining three-fifths to the centre, south and south east are characterised by the Cretaceous formation (Cunnington, 1938). The pre-Chalk formations also extend eastwards through the 5 a Fig. 1—Known distribution of Micromys in Wiltshire relative to the main river systems Vale of Pewsey, thus dividing the Chalk of the Marlborough downs from the main chalkland area of Salisbury Plain. Aubrey found the proportion of downland to be three-quarters of the county; he wrote “To find the proportion of the downes of this countrey to the vales, I did divide Speed’s map of Wiltshire with a pair of cizars, according to the respective hundreds of downes and vale, and | weighed them in a curious ballance of a goldsmith... .”(Aubrey, 1847). This - ingenious method would have been very accurate and the loss of downland since the mid-nine- teenth century could be attributed to additional land soing under the plough, probably within the last 35 years. = E The county is drained by 3 rivers. The Thames, flowing from west to east in the extreme north, is joined by the tributary Kennet outside the county boundary and together they flow eastwards and eventually into the North Sea. The Bristol Avon rises in the north west and flows in a southerly direction to discharge into the Bristol Channel and eventually) into the Atlantic. The Salisbury Avon and its tributaries drain the whole south of the county ‘and, moving generally in a southerly direction finally flow into the English Channel. The northern escarpment of Salisbury Plain forms almost exactiy the mid-line across the county, although the vice county division is formed by the Kennet and Avon Canai several miles further north. Much of the north-western part of the county on the Jurassic is fairly level, characterised by pasture and woodland. These comparatively low lying areas are broken by harder rock which forms ridges and hills and, in the extreme north west, there are the steep limestone valleys of the southern Cotswold foothills. The south and south-eastern three-fifths of Wiltshire are characterised by rolling chalk downland intersected by the broad valleys of the Salisbury Avon and its chief tributaries the Wylye and the Nadder. Here the river banks are bordered by lush water meadows. The chalk does not support trees with the exception of plantations of beech but, where sand or gravel lies above the chalk, trees grow well. Green- sand, Gault and gravel subsoils support a good tree growth and chalk valleys where these soil conditions prevail may be thickly wooded. It has been shown that, in general, the wetlaad habitat is of great importance to Micromys and the map of Wiltshire, showing the main rivers with extensive water meadows in the north and south of the county, would suggest ideal breeding conditions for the species. However, the water meadows, found by Piechocki to be “specially favoured” in Germany, do not appear to be so favoured in Wiltshire and Micromys have not been recorded in them by the authors during the current survey. A detailed examination of the county's water meadows reveals that they are fairly heavily grazed and that little or no fringe vegetation is left to provide suitable breeding sites for Micromys. Generally speaking, Micromys have only been found in the wet- land habitats when these are in association with arable fields and these conditions often occur along the streams tributary to the main rivers. This relationship is illustrated in Fig. 1 which shows the current distribution of Micromys in Wiltshire and the river systems of the county. In spite of the apparent importance of arable fields to Micromys in Wiltshire (cereal crops were listed in the habitat requirements of 32 of a sample of 36 recorded sites in the county) no nests have yet been recorded in standing corn. However, on the Wiltshire/Avon border Micromys nests were found in straw left lying in 2.cernfields after the 1974 harvest. These nests had passed virtually intact through the combine harvester and in some cases were still loosely attached to the corn stems in which they had been built. This emphasises local variation in the use of the arable habitat. In Wiltshire it appears that arable fields are unimportant in their own right as Micromys sites, but their proximity to other potential habitats is of great signific- ance. This observation is further substantiated by the many breeding records of Micromys in fringe vegetation surrounding arable fields. The fringe vegetation provides a vanety of Gramineae spp. suitable for nest construction as well as other plants including Ruwmex spp., Carduus acanthoides, Vicia spp., Urtica dioica, Epilobium angustifolia and Centaurea nigra, all of which have been used as stalk zone support. Where the fringe vegetation grows along a fence, the supporting plants are themselves supported by the lower strands of wire thus pro- viding a very firm growth which is not easily destroyed by adverse weather conditions. When the Gramineae spp. and supporting plants grow under a yhedge, additional support is again provided by the lower branches of hedgerow shrubs such as'Crataegus monogyna and P.spinosa, shelter being thus offered as well as support. Waste grassland sometimes supporis smal! numbers of Micremys, and shelter nests have been found on waste patches at corners and junctions of country roads and on rcadside verges. Even a certain amount of disturbance does not necessarily deter the mice and 2 nests were con- structed at Dauntsey Green near a country bus stop. ‘This site was frequented by dogs as well as by humans and although the nests were iong abandoned by the time they were found in May 1974 they were still in good condition, being hidden in dense clumps of D.glomerate, and were considered to be shelter nests consiructed and used the previous autumn. Some of the larger colonies of Micromys have been found in young plantations, which provide an ideal habitat in Wiltshire as elsewhere. The exact age of plantation when V&cromys first move in has yet to be determined but it appears that conditions are ideal when the young trees reach a height of about 120 to 15Ccm. By this time the trees are well established an¥ com- _pete satisfactorily with ground cover plants. Weeding ts no ionger necessary and grasses such as D.glomerata, “Arzhenatherum elatius and D.cespitosa are given suppert by the iower branches of the trees. Brambles add extra buik to the ground cover and a habitat ideal for Micromys nest building is thus provided. As the plantation grows it eventually reaches a stage when it is no longer suitable for use by Microniys, the gre adnal development of a cano py reduces or elimin- ates the grasses growing beneath and may also result in unacceptable loss of light and warmth. It is thought that some Micromys spend part of their ae ves below ground in arable fields. They are normally too sma!l and light to have much facility for digging, but when the soil has been loosencd by rotavating or ploughing this might provide Seon tae where it would be poss- ible for them to dig. Montagu (c.1785) subscribed to this view and wrote “li winter they burrow deep in the ground forming a bed of dry grass for warmth.” In recent years one of the few live sightings of Micromys to be recorded in Wiltshire was a mouse found underground in August 1974. It was about 5 cm. below ground in a hole, lined with a small quantity of shredded straw, which was situated between lines of oat stubble approximately 150cm. from the edge of a field which had been cultivated close to the boundary leaving very little fringe vegetation. The mouse was located and dug out at dusk by a badger cub and, by shining a torch into the hole, a very clear view of the mouse was obtained. Apart from this one chance iene no evidence of underground activity is known to have been recorded in Wiltshire in recent tin Montagu’s descripticn of Microm ys nests accord well with modern observations—‘It makes an elegant round nest SUPP orted ai some distance from the ground in a smail bush, thistle or coarse grass by the sides of hedges. “Mr. White very justly observes there is no finding an aperture to the nest and naturally concludes a fresh one is made every time the young ones are visited and that it is carefully adjusted by the old mouse when she leaves her litter’ (Montagu, c1785). Some years later he wrote “The nest was globular two inches and a half diameter; composed externally of the blades of corn; internally ef the finest hairhke grass; these materials are... .interwoven without any opening, the cavity aie scarce more than an inch diameter and apparently no room for the dam to give suck to the young. It is certain with such a structure a perforation must be made every time the old one visits the nest, and carefully closed again on leaving it” (Montagu, 1802). It is possible that the second nest described, with its smalt cavity, was in fact a shelter rather than a breeding nest. Micromys nests recorded recently in Wiltshire vary little in shape, being spherical when newly constructed, although some distortien is caused by the mice pushing their way in and out. In many cases the nests are discovered long after use when they are much battered by Wind and rain; often indeed the whole supporting plant, complete with nest, is found flat upon the ground. Whatever the condition of the nest it is, however, usually possible to discern the original shape. Quite often incomplete nests are found which have been started and then abandoned. When finished the nests are compact, neatly woven balls. Some, perhaps 4 or 5 cm. in diameter are very finely shredded and have no lining; these are of a size to house one mouse and are believed to be shelter nests. This theory is supported by the recording, in Wiltshire, of 2 nests of this type and small size, each of which housed a dead sub-adult jes Larger nests with discernible outer and inner layers have also been recorded and sometimes have the leayes of other plant species woven into them, but interwoven flowers and seed heads have not been found in Wilt- shire by the authors. Nests consisting of 4 layers as described by Shiraishi are also unknown. 8 ACKNOWLEDGMENTS The authors would like to thank the Linnean Socieiy of London for making available the original manuscripts of George Montagu; Sicphen Harris for keeping them up to date with the findings of the Mammal Society’s Nationa!

G. EVANS In two previous papers I recorded sub-fossil mollusc faunas from Jate Pleistocene deposits in Wiltshire (Evans, 1968; 1969). Further deposits in which cold-climate faunas were present were revealed at Marden (SU 091584) in the Vale of Pewsey during the archacological excavation of a Neolithic site. These have been reported briefly (Evans in Wainwright, 1971) but it has not been possible until now to make a detailed study. The importance of Marden isthat two distinct faunas were present, the one stratified above the other. The faunas were in a chalky solifluxion deposit about 0.75m thick overlying UppeGreen- sand (Fig. 1). The sequence was a follows: Post-glacial deposits. Bank of Neolithic henge monument and buried soil Pleistocene deposits Involutions. Pockets of fine sediment (d) Coombe rock. Angular chalk and flint debris (c) Bedded gravels, contorted by freeze-thaw action (b) Silt fens (a) Upper Greensand Base of Post-glacia! soil Upper Greensand Oo 1 2m Fig. 1—Marden. Section through the deposits. Fossiliferous layers black. a, silt lens; b, sand and gravel; c, coomkerock; d, involutions 5.0 kg of material from the silt lens was analysed and a molluscan fauna of about thirty- four species extracted (Table 1). Dry land and marsh forms predominate and are mainly those which today inhabit open country. The association of marsh species with xerophiles such as Helicella itala is a common occurrence in cold-climate faunas. The abudnance of Pwpilla and Succinea is particularly characteristic. The phenomenon has been explained in terms of a mosaic of habitats—shallow pools, marshy ground and raised hummocks—and in terms of the cool climate which, in reducing evaporation, probably enabled hygrophiles to colonise drier habitats than is possible today. oe eee A number of freshwater species are present. The majority can either tolerate poor water conditions—e.g. pools subject to seasonal drying—or live in a wide range of habitats. A few, however, namely Planorhis planorbis, Pisidium amnicum, P. subtruncatum and P. henslowanum, are ecologically anomalous in that they live today in moving-water habitats. The good pre- servation of the shells and the absence of other freshwat@r forms which might have been expected, had the deposits been of fluviatile origin, make it unlikely that these species derive from earlier deposits. A possible explanation is that the cooler conditions of the Last Glaciation increased the oxygen -holding capacity of the water thus enabling them to live in smaller pools than those which they inhabitat today. 10 Climatically, all the species have a wide tolerance. The presence of two subspecies commonly found in cold-climate deposits, although not restricted to them, supports the idea that the fauna derives from a cold period. These are Succinea pfeifferi schumacheri and Pisidium obtulsale lapponicum. Pupilla occurs as two distinct forms. One is the small variety common - today; the other is a larger, parallel-sided form characteristic of cold Pleistocene faunas. Three species, Carychium, Truncatellina and Vertigo substriata, ave generally restricted to the more temperate periods of the Pleistocene. All have, however, been described as occurring in the early stages of the Last Glaciation (Sparks, 1964), and it is probably to this period that the fauna at Marden belongs. Teeth and bones of voles were prolific in the silt lens, and these were identified by Mr. G. B. Corbet as follows: Microtus aryalis!/M. agrestis M 5 1 2 M. arvalis/M. oeconomus 3 M 1 Microtus sp. 3. M All three species are characteristic of grassland habitats. M. agrestis and M. oeconomus live in moister situations than M. arvyalis. The second fauna at Marden comes from the involutions (d) at the top of the sequence (Fig. 1). 3.0 kg of material yielded a terrestrial fauna of cold-climate type (Table 2). As in the case of the silt lens, a marshy, open-country environment is indicated but without the fresh- water pools. The fauna is much more restricted, however, and lacks many characteristic late- glacial species such as Vallonia and Punctun: (Evans, 1968). The dating of both faunas is difficult. The earlier one from the silt lens is possibly of early Last Glaciation origin as suggested by the presence of a few relatively thermophile species and the general richness of the assemblage. The later fauna is of fully cold-climate type but its position within the Last Glaciation cannot be ascertained. It is worth noting that a number of the species in these faunas no longer live in Wilt- shire. The nearest colony of Catinella arenaria is Braunton Burrows in Devon. Truncatellina occurs in isolated colonies in eastern England. but was still present in Wiltshire during the Bronze Age. Vertigo genesii and Columella columeila are totally extinct from Britain. ACKNOWLEDGMENTS I would like to thank Dr. G. J. Wainwright for excavating the trench through the deposits at Marden and thus making this study possible. Dr. M. P. Kerney and Mr. S. P. Dance kindly helped with the identification of the shells of Pisidiuwm and Succinea, and | am grateful to Mr. G. B. Corbet and Dr. P. N. Ferns for identifying the vole teeth. REFERENCES - Evans, J.

The 1973 Report drew attention to five successive dry years and speculated as to whether a long-term climatic change was in progress. Hardly had the ink dried before the skies opened and produced the wettest January and February together since 1937! Is it any wonder that there are so many superstitions associated with the study of weather? The opening two months of 1974 were persistently warm, wet and unsettled. Rainfall at 261.8mm (10.3ins.) was almost double the average and the mild temperatures, particularly in January when only two air frosts were detected, made it the warmest start to a year since 1921. The Winter of 1973/4 certainly matched those of 1942/3, 1948/9 and 1956/7 for mildness, but there were frequent SE-SW gales which, together with the rain, often made for very unpleasant conditions. However, just when we were getting ready to herald Spring, easterly winds spread to most southern districts in March and snow was recorded on the Ist and more especially on the 10th. It did not lie for long and the end of the month was ven variable with frequent fog and even a thunderstorm activity on March 25th. 13 April and May were dry and sunny (the driest since 1956 and the sunniest since 1959) but there were quite a few cold spells and the growing season was certainly not ahead of its usual schedule. June and July were very average, the weather during this period tending to be unsettled, but generally pleasant. The period March-July, inclusive, produced only 169.9mm (6.7ins.) of rain, making it the driest such spell since 1938. Many articles were being published warning of severe drought and advising farmers that they would need to adapt to a drier Britain, but rain fell on Swithun’s Day and the monsoon was not long in arriving! August and September together produced some very freak weather: waterspouts in the Channel, a tornado at Woking and a whirlwind at Folkestone were all reported. At Marl- borough 301mm (11.8ins.) of rain was recorded in these two months making it the wettest August and September combined since Marlborough College started its meteor logical records in 1865. It was also a very chilly end to the Summer and the cold spell continuéd into October which, with a mean temperature of 6.9 degrees C (44.4degrees F), was the coolest since 1914. The rest of the year was warmer, particularly December. Winds were generally light, allowing widespread fogs to develop in November, but rainfall was not m uch above the normal for this time of the year. On the whole 1974 was mild and distinctly wet. Rain was recorded on no less than 206 days, whereas in 1966, which was actually slightly wetter, only 186 wet days were registered. \- 14 WILTSHIRE BIRD NOTES FOR 1974 RECORDER: G. L. Webber. Recorps Committre: Mrs. R. G. Barnes, G. K. Boyle, E. J. M. Buxton, R. J. J. Hunt. This list has been reproduced from the fuller report being published by the Wiltshire Ornithological Society. Both reports draw from the same pool of records, these being scruting ised by the sanie Records Committee. One new species was recorded in the county this year. A Long-billed Dowitcher spent 10 days at Swindon Sewage Farm in September. & Due to its tameness it provided excellent watching for hundreds of observers. Other interesting species included a Grey Phalarope at Poulshot in January and a Black-necked Grebe at Coate Waiter in early February. Both were probably storm driven by the violent gales in January. The Barnacle Goose found dead at South Marston and the Goshawk at Imber in September were presumably escapes. Swindon Sewage Farm produced an impressive list of migrant waders in the Autumn. Although the Dowitcher took pride of place, the Temminck’s Stint was only the second county record. Amongst breeding species the Stone Curlew apparently enjoyed its best season for many years raising hopes for the species future within the county. I would like to thank all contributors who supplied the information without which this report could not have been written. Due to the increased postal charges receipt of record slips was not acknowledged in many cases.

FAULKNER Further decreases in the numbers of birds ringed in Wiltshire during 1974 (804 free-flying birds and 387 nestlings) may be partly attributed to the departure from the County of more ringers, but also to a general drop in ringing activity. Of special note are five Lapwing one Redshank, and six Little Ringed Plover nestlings, all ringed by GLW, and a free-flying Dunlin and Tree Pipit, also ringed by GLW. A LIST OF CONTRIBUTORS L E. J.

The common things like weeds flourish in any conditions. The rarities having a much lower subsistence level are extremély vulnerable to adverse factors. “ We noticed plenty of the usual hibernators on the wing quite early when the teniperature was in the 50’s and the sun tempted them out. By mid-March the sallows were full out and swarming with insects day and night, but nothing of special interest was reported. The cold winds prevailing in May and June must have discouraged the migrants badly for there were very few sightings of the Red Admiral, Painted Lady or Clouded Yellow, even the Silver Y was scarce. After a succession of mild winters the decline of certain species may seem to indicate that a hard winter tends to protect the pupae in the ground, whereas in mild soft weather they are more vulnerable to probing birds, etc. Also as EJ MB suggests, the loss of so many elms through Dutch Elm Disease, itself favoured by mild winters, may have a serious effect on par- ticular species. There are many gaps to fill and the more observers who send in their records the better the picture.

Not all records received have been included here but all have been deposited at the county Biological Records Centre with grid references. It would be helpful if contributors cguld include a map reference when submitting records in future. 4 As most mammalian species feed either at night or in dense vegetation and leaf litter, it is not surprising that casual sight records are few. However, evidence of the presence of most species can be detected if their signs can be recognised—tracks, feeding signs, droppings, nests and skeletal remains in bird pellets, etc. and records of these signs are acceptable for most species. A useful reference book is “Collins Guide to Animal Tracks and Signs” by Bang and Dahlstrom. With the exception of some bat species, most of which can be identified only in the hand, all mammals known to occur in Wiltshire are mentioned in the following notes, and an indic- ation of their status in the county Is given.

Several sites had been destroyed either by ploughing or by the grass having been cut and searches in a sample of previously occupied sites were unsucgessful. No nests with young were found in Wiltshire though some mighty have been found with further searching. Reports from other Southern counties also showed ° a reduction in the number of breeding nests found. This was attributed to the very bad weather during July, August and September when the long grass was repeatedly battered by heavy rain and strong winds making conditions for nest construction very difficult. On 20 November, 1974 a party of members of the Salisbury and District Natural History Society was shown how to find Harvest Mouse nests. A search was made of the wide grass verge either side of a 200yd. stretch of road near Wilton and 80 nests, including 12 which had probably been used for breeding, were found. In 1975, the same area was searched soon after the crop in the adjacent field had been harvested when the beginnings of two nests were found. Two weeks later, on 10 August, a total of 13 were found but none contained young. Following eight weeks of hot, dry weather most of the Dactylis glomerata leaves were already too dry for shredding and the nests had been constructed of Arrhenatherum elatius, Trisetum flavescens and Holcus lanatus and leaves. Most were built in positions where they were largely supported by stout herbs or small shrub suckers. ache no Although nests were found in other counties in 1974 which had passed almost intact through the combine harvester, none have so far been found in Wiltshire. a Unfortunately, there was no response to the note in WAM 1974 hoping for assistance with the survey and a disappointing response from members to the two field meetings arranged in the autumn of 1974. It is hoped that more interest will be shown in future meetings designed to help with the survey. Thanks are extended to the following new recorders for their help in°1974—D. A. Beeson, Miss A. Cardus, J. A. Carman and Mrs. A. Kelham. + 31 SHORTER NOTES Vulpes vulpes THE PIG’S HEAD, 1974 Spring 1974 was very bad with a lot of rain, two days of snow early in March and a very cold April with the wind in the east. It was much too cold for young cubs to be above ground and I saw none until the beginning of May, when the wind shifted to the west and it was Warmer with spells of sunshine. : At 17.00 hours on 2nd May I was walking along the northern boundary of the farm and saw a cub ona broken stone wall by a gateway. 1 sat down in the hedge to watch and presently more cubs came out to play and I counted five. They were clambering on to the broken wall and hopping off again. Their coats were a bit woolly, their tails still ratty and they were not yet in full control over their legs. I judged them to be about six weeks old. By 18.00 hours the evening was chilly and the cubs went below. There was no sign of the vixen and I went up to the earth carefully to see what it was like. It had been used briefly the previous year as a temporary home for four cubs, with two holes in use on either side of a dry stone wall overgrown by hawthorn. Excavations had been extended about eight yards west to a point where the dry stone wall met a wide hedge to form a T junction. Immediately north of the junction was the broken wall and the gateway. There were two new holes, one on each side of the broken wall. The hole on the east side was covered with dense nettles and hawthorn but the west hole was exposed and the spoil heap was worn smooth by contant use. The arrangement gave the cubs a choice of three fields to play in, two fields of Spring corn on the east side and a field of mowing grass on the west side; whatever the wind direction they always had a sheltered place to play. The area round the earth was littered with bones, pigeon feathers and cub droppings. It was unusually smelly even for foxes and I did not expect them to stay there for very long. The next three days were cold and although I paid brief visits to the earth I did not see the cubs. On 6th May there was a cold east wind but there was warmth in the sun and I decided on a longer watch. I reached the earth at 14.30 to find the remains of a large pig there. It had been dismembered by the foxes, much of the flesh had already been eaten and various bits and pieces had been taken by the family and left lying about. The head was near the earth, legs and trotters were here and there in the mowing grass. No fox could possibly have killed so large an animal, the pig had probably died and had been left out for foxes to take. Foxes are useful animals to have ona farm, feeding as they do mainly on rabbits, pigeons, rooks, rodents, insects, fruit and carrion. Many farmers value their presence, knowing that the local hunt will keep the number of foxes in check and that old and weak animals are usually the first to be killed by hounds, leaving strong foxes which will take natural prey rather than domestic stock. This vixen was certainly strong, she had dragged the pig at least 300 yards. After examining the pig and considering the best place to sit | tucked myself into the hedge about five yards north of the gateway with a south west wind blowing my scent well away from the earth. I waited for about an hour. There were no cubs out and considering the smell, which grew worse daily I wondered if the family had already moved. At 16.00 hours there was a red blur in the hedge at the far end of the mowing grass and presently the vixen came into the field and began a careful approach to the earth. She carried no food and had come to visit and probably suckle the cubs, The grass was high enough to cover her as she moved nearer but at intervals she stopped and raised her head cautiously to look all round and to sniff the air for signs of danger. Her path was a zigzag line making a wide sweep of the field before the final approach to the earth. As she worked nearer she became uneasy and although she had not spotted me she seemed to be aware that something was wrong. She was a very beautiful animal with a shining healthy coat, russet with a darker streak) on the nape, white belly, no tag and a most unusual black bib. This bib, large and evenly rounded, would have made her instantly recognisable but I have not seen her before or since When she was about 25 ft. away she saw 32 f te & rivenad, : ; bots a me and froze. To be more exact, since I was unmoving, she saw an unfamiliar shape in the hedge. After a pause she moved carefully a few feet nearer the earth and then looked again directly at me for several seconds. This time her courage failed and she bounded away, her brush flowing over the grasses, and vanished through the hedge where she had first appeared. There was no sign of the cubs and, as far as I could tell, no vocal signal to them from the vixen. I struggled further into the hedge without much hope but at 16.15 she came again and made the same careful approach as before, creeping through the grass and raising her head at frequent intervals for a good look round. She looked repeatedly in my direction but continued to move carefully on and was within a few feet of the earth, when once again, her courage failed and she flowed away through the mowing grass and into the far hedge. She obviously wanted to reach her eubs so, giving the earth a wide berth, I walked openly away. I could not see,her but she was almost certainly watching me go. ‘ The following day, 7th May, I watched the earth from 14.30 until 17.15 without seefng cubs or vixen. Approaching the earth carefully I found that the pig’s head had been dragged further into the grass. When I was six feet from the broken wall I realised that a cub was sitting by it chewing a rabbit’s leg; I stood still, watching, for about a minute until the cub suddenly looked up, saw me and backed into a hole dragging the rabbit’s leg after it. I moved further away and at 18.00 hours four cubs came out and played on the bare patch at the west entrance, climbing on and off the broken wall, a favourite game. By 19.30 all were below ground. On 8th May I watched from 17.00 until 18.30 hours without seeing any cubs. There was rather a cold south west wind. The pig’s head had been moved again and more of it eaten. There were new trails through the grass and fresh droppings to show that the foxes were still in residence although the increasing stench made their removal seem imminent. It was hard to imagine such a large family living for so long in such a small earth; conditions underground must have been unusually insanitary, yet the cubs thrived. Several days of rain followed, then on 14th May it was warm and sunny and J took friends to watch the cubs. There were four of us, too many for a close approach, so we took binoculars and sat under a hedge 100 yards from the earth with the wind in our face to blow our scent away. At 17.30 one cub made a brief appearance but there was not much activity until 18.30 when all the cubs came out and we saw that there were in fact six of them. Four were fawn, one with a white tag; the other two were red, one with a tag slightly paler but not white. The two red cubs were darker on the shoulders, a pattern which recurs year after year in this fox territory and which seems to be inherited; I first noticed it about nine years ago when the resident dog fox was a remarkable animal, very big and almost black over the shoulders. He was at least six years old when last seen, well above the average life span of a wild fox. I never knew how he died but it is unlikely that he was killed by hounds, he was always more than a match for them. The cubs were sleepy at first and tumbled lazily about together, but gradually their play grew more energetic. They were beginning to split up and two chased each other up and down the hedge while one jumped about stiff-legged by itself not to be diverted by any of the others, which were stalking and trying to ambush it in the long grass. They were all getting bolder and venturing further afield but play still brought thém rushing back quite often to the broken wall by the earth. At 19.30 it was chilly and we crept away leaving the cubs still at play. By this time an orphan badger cub had arrived and [ was rearing her for release in the Autumn. This meant spending a good deal of the night with her because for survival she must learn to forage nocturnally. Inevitably this cut down my day-time activities but [ visited the earth often even if briefly. It was now definitely unpleasant to be anywhere near but still the large family was living there. Every day fresh droppings and new trails through grass and corn revealed their presence. The pig, now reduced to bits of skeleton, turned up in different places further and further afield. The skull in particular seemed to be a special treasure and was left in a new place every day. By 2lst May two more holes were in use some distance from the earth in a hedge. 1 saw the two red cubs and one fawn cub near the earth but their sleeping quarters must have been cramped and the others had probably moved out. The vixen would have left them and be kennelling elsewhere, but probably still visiting them daily] They all remained fairly close together for another two weeks, toying with the pig bones and moving the skull about. 33 i ve rin rete? ager te APs > igh Oey On 4th June the skull was left so far from the earth that | pass it had been}finally abandoned and took it home with me for a friend who was making a collection of mammal skulls. I left it in the garage temporarily and when I returned one ou fee it had gone. A dog seemed the most likely culprit, but the following day the skull was back in the mowing grass near the earth. Part of the garden, including the garage, forms one boundary of this fox territory so I came to the conclusion that the vixen on her rounds came across the skull and took it home with her. Was it just a promising bone that she came across or could it nave been a long treasured family possession? I shall never know. By 7th June one red and one fawn cub had moved to the main earth in a thicket and they were pottering about outside at 17.40. The other four were still playing by the temporary earth but ranging very far afield; they would soon be moving to the main earth too, quarter of a mile away. I often wonder if they took the pig’s skull with them, I never saw it again. RENARDE . STOP PRESS During June and early July, 1975 three litters of fox cubs have been coming in to take food put out for them at a nearby farm. Some of them are much younger than others and must have been born very late in the year. Another household started to put out food and at any time after about 22.00 hours the cub families could be heard moving round the village, playing and squealing as they went. They were easy to watch from a window ox the roof of a shed and were often seen crossing or playing in the lane. One night some food was put out in a plastic dish and in the morning the dish had gone as well as the food. After hours of search it was eventually found outside one of the earths and had evidently been taken home by the foxes. An interesting comparison can be made with the behaviour of hyaenas. During a three- week stay in Serengeti Reserve last winter it was always wise to take anything portable indoors at night. Hyaenas would take away shoes, dustbin lids, washing-up bowls or anything else they came across which they could carry. They might have been able to eat the shoes but it is difficult to think of any use they could find for a dustbin lid.

The Chairman, Mr. G. L. Webber welcomed all those present and asked the Hon. Treasurer to present the accounts. Mr. Smith stated that the balance of £14 from Jan 1974 had been reduced to 90p, but considering the increased costs—over £100 for stationery postage and telephone—the year’s deficit of £13 was not surprising, however the motion on the Agenda for an increase in subscription seemed fully justified. See NG During the year there had been 14 outdoor and three indoor meetings; the increase cost of travelling seemed to have affected the attendance for indoor meetings more than the outdo ar which had covered'a wide range of natural history. o Mr. Webber then explained that with much regret he could not continue as Chairmart as his work would take him out of the County. In his place he would nominate Mr. C. E Jennings, who was elected unanimously. The new Chairman after thanking Mr. Webber for his valuable work as Chairman and as recorder for the Bird Notes, outlined several necessary changes in Officers and Committee members. Mrs. Joan Swanborough was elected to be Hon. Secretary and Mr. R. S. Barron to be Hon. Editor; for vacancies on the Committee Mr. R. E. Sandell, Mr. M. Gould, Mrs. J. Heath and Mrs. M. Browne were elected. Thus for the first time for very many years familiar names such as Gillam and Barnes, to whom the Section has owed so much, will no longer appear on the Committee list. Miss Gillam who came on to the Committee in 1952 had been both Meetings and General Secretary, Mr. Barnes had been Chairman for seven years and Mrs. Barnes had served for 30 years in one capacity or another. Mr. and Mrs. Barnes had also provided generous hospitality at their home for the Committee meetings. In recognition of their kindness the Committee had given them a Sorbus tree for their garden. After approval of the increase in subscription rates to £2 single, £3 family and the reappointment of Mr. Penny as Hon. Auditor, Mr. Sandell spoke on the progress ‘of the Flora Supplement publication. A thousand copies would be printed at a cost of £2,500, they would be sold at £4 or £4.50 when posted.* The payment to the publisher would be met by the balance of £600 in the Flora account and the remainder by an interest free loan from Committee members. Mr. Barron explained that the parent society had decided that, for an economy, thes would not in the future publish W.A.M. part A as such but would welcome the Section to publish a magazine which would be available to all full Society members who apply for it. Ali Section members will of course receive their magazine as formerly but some delay will result from the changes. After the meeting many members, under the guidance of Mr. Stonell, went on a walk around Roundway Hill Covert. Throughout 1974 much discussion and thought had been applied to the proposed W.C.C. appointment of a Curator for Natural History in the County, but economies imposed by the Government on the County Council prevented the fulfilment of many expectations. On the other hand a Natural History Forum was set up to combine the individual efforts of all those interested in Wiltshire’s Natural History into one effective body. The first meeting of the Forum was devoted to Biological Records with Dr. F. Perring as the chief speaker. Consequently a County Records Centre has been set up with Mr. R. Sandell as the Hon. Recorder. ay Out of doors a number of members have helped with the National Rookery Survey for 1975 initiated by the B.T.0. Miss B. Gillam and Mrs. M. Browne have continued their work for the Harvest Mouse Survey and will welcome more help. Mr. Jennings at the A.G.M. had also outlined other surveys including one for hedges. that the Section will undertake so there is plenty of work for all members and for those who may not be members at the moment. * The Supplement was published on October 27th; copies cpn be had at the Museum or by post. 35 x= ae at ait an Mi Orit Sits ——— sytiet | A conor! ey ee pews eS “=: = ae Se tees Sere 4 a = = San gNin Se ne ee eas SSS SS See wat ee = a tan one ene ee oat Serna ere repent ligt ences
