Dennis Published by: The Scottish Ornithologists’ Club, 21 Regent Terrace, Edinburgh EH7 5BT Secretary: Major A. D. Peirse-Duncombe THE SCOTTISH ORNITHOLOGISTS’ CLUB The Scottish Ornithologists’ Club was formed in 1936 and membership is open to all interested in Scottish Ornithology. Meetings are held during the winter months in Aberdeen, Ayr, the Borders, Dumfries, Dundee, Edinburgh, Glasgow, Inverness, New Galloway, St Andrews, Stirling, Thurso and the Wigtown District at which lectures by prominent ornithologists are given and films exhibited. Expeditions are organised in the summer to places of ornithological interest. The aims of the Club are to (a) encourage the study of Scottish ornithology and to promote an interest in wild birds: (b ) co-ordinate the activities of Scottish ornitholo- gists; (c) encourage ornithological work in Scotland; (d) encourage conservation of Scottish birds and protection of threatened and rare species; (e) hold meetings for discussion and to arrange ornithological field meetings, and (f) appoint local recorders and publish material relating to Scottish ornithology, including Scottish Birds , the club journal. There are no entry fees for Membership. The Annual subscription is 27.50, or £3 in the case of Members under twenty one years of age or Students under 25, who satisfy Council of their status as such at the times at which their subscriptions fall due. The Life subscription is £150. Family Membership is available to married couples and their nominated children under 18 at an Annual subscription of £1 1 , or a Life subscription of £225. Scottish Birds is issued free to Members but Family Members will receive one copy between them. Subscriptions are payable on 1st October annually. Scottish Birds, which is published quarterly, includes papers, articles and short notes on all aspects of ornithology in Scotland. The club also publishes the annual Scottish Bird Report. The affairs of the Club are controlled by a Council composed of the Hon. Presidents the President, the Vice-President, the Treasurer, and ten other Members of the Club elected at an Annual General Meeting. On the Council is also one Representa- tive of each Branch Committee appointed annually by the Branch.

Edinburgh EH7 5BT December 1982 Printed by Capital Print. Unit 4, Thorntreeside. Easter Road, Edinburgh EHb INTRODUCTION 1981 was a really exciting year for bird-watchers in Scotland; a record total of 325 species were identified during the year and recorded in this report. 87 rare birds were recorded and 38 of these were represented by only a single individual. Ten species were considered to have escaped or been released from captivity or were of doubtful origin. Surprisingly in a year of plenty only one new species was added to the Scottish List but that was a dramatic addition - a Sandhill Crane from North America, which arrived at Fair Isle on 26th April and departed next day. Year 76 77 78 79 80 81 No. of species recorded 314 305 298 323 315 325 No. of new species 4 4 2 6 4 1 Other rare vagrants included American Bittern, Purple Heron, American Wigeon (2), Black Duck, Gyr Falcon, Stone Curlew, Kentish Plover, Lesser Golden Plover, Buff -breasted Sandpiper (3), Great Snipe, Wilson’s Phalarope (4), Franklin’s Gull, Bonaparte’s Gull, Ring-billed Gull (2), Ross’s Gull (4), Alpine Swift (3), Olive-backed Pipit (2), Citrine Wagtail, Red -flanked Bluetail, Eye-browed Thrush, Black-throated Thrush, American Robin, River, Pallas’s Grasshopper, Savi’s, Booted, Sardinian, Pallas’s and Bonelli’s Warblers, Isabelline Shrike (2), Woodchat Shrike (2), Trumpeter Finch, Rustic (4), Yellow-breasted (4) and Pallas’s Reed Buntings.

Snow storms and cold weather, especially in southern Scotland, held up spring passage in late April and adversely affected early nesting birds. There was a dramatic fall of migrants on the east coast in May, especially Bluethroats with about 275 of these lovely spring migrants in mid-May. The early autumn passage was disappoint- ing but big falls of Scandinavian night-migrants occurred later in September and October, with a good sprinkling of rare vagrants. A very interesting arrival of Bean Geese occurred in many areas which resulted in higher than usual wintering numbers. The year ended with very cold conditions which caused heavy mortality of many species. Seabirds (including terns in the north) had a generally good breeding season and Red-throated Divers also did well. Birds of prey were affected by the severe weather in the spring and breeding success was low for some species, but Ospreys had their best ever season with 20 pairs rearing 42 young. Goldeneye also had an excellent season with 29 successful ducks hatching a total of 286 young; Ruddy Ducks continued to increase although breeding success was again nil. Quail bred successfully and three broods of Purple Sandpiper were recorded. Green Woodpecker and Jay continued their northward expansion and there was an interesting upswing in Lesser Whitethroats in the nesting season. No Wrynecks, Red-backed Shrikes or Lapland Butnings were found nesting but Snow Buntings had a good year. Notes on Compilation: This report is published by the Scottish Ornithologists’ Club and should* be regarded as part of Scottish Birds Volume 11 (and can be bound with that volume). For new recorders it should be noted that the report is a concise (and at times terse) summary of data collected on all species known to have occurred in Scotland in 1981 and no attempt is made to define the ordinary status of most species. Precedence is given to peak numbers, migration patterns, first and last dates, records in unusual areas etc. All records of semi and national rarities are given while for some species the data has been summarised in table form. For further information readers can refer to The Birds of Scotland (Baxter & Rintoul 1953) or previous Scottish Bird Reports which are still available from the Secretary. As before we stress that observer cover in various regions of Scotland ranges from very good to pretty thin and care should be taken in comparing numbers and regional distribution, especially of migrants. Generally speaking, the Northern Isles, the North Sea coast, central Scotland and the Clyde/Solway are aS 3X e better covered than elsewhere, but there are pockets of good cover in most regions. For some areas, more information is published and greater detail given in the local bird reports. Although much local information cannot be published here, the collection of records by the local recorders provides a most useful fund of reference data for regional ornithology. At the request of the SOC, the British Trust for Ornithology has started to provide a print -out of Scottish ringing recoveries which will allow us to include an annual contribution on bird ringing recoveries of Scottish interest in the S.B.R. We are very grateful to the BTO Ringing Office for this service. I am very grateful to A.R. Mainwood who has offered to write a summary for the S.B.R., and even more so to him this year as he has managed to rapidly write a summary from the recently received data. In order to get it in this S.B.R. we have used a photo-reduction of the word processor print-out so we apologise for the very small type. 5 ACKNOWLEDGEMENTS I would like to thank everyone who has contributed or helped with the 1981 report, including the observers who sent in the records and especially the local recorders who collated the records and produced the area reports. My grateful thanks to John Love for the Crested Tit on the Cover and to A. Dowell and D.G. Mitchell for vignettes. LOCAL RECORDERS Shetland (except Fair Isle) R.J.
