VOL. XLVIII NOVEMBER No. 11 1955 BRITISH BIRDS REPORT ON BIRD-RINGING FOR 1954* By ROBERT SPENCER, B.A., Secretary, Bird-Ringing Committee of the British Trust for Ornithology THIS is the eighteenth report issued on behalf of the Committee, continuing the earlier sequence under the title "The British Birds Marking Scheme". It combines a report on the progress of ring ing between October 1953 and December 1954 with a selected list of recoveries reported up to 31st December 1954. MANAGEMENT The members of the Committee are as follows: Sir Lands- borough Thomson (Chairman), Miss E. P. Leach, A- W. Boyd, Hugh Boyd, J. A. Gibb, P. A. D. Hollom, G. R. Mountfort, Major-General C. B. Wainwright, George Waterston; Sir Norman Kinnear; Bruce Campbell and C. A. Norris (ex officiis); Robert Spencer (Secretary). The only new member of the Committee is Sir Norman Kinnear, who succeeded Lord Ilchester as representa tive of the Trustees of the British Museum- A Sub-committee comprising Hugh Boyd, C. A. Norris, Major-General C. B. Wain wright and the Secretary was formed to plan the development and production of new rings. By permission of the Trustees, the headquarters of the scheme remain at the British Museum (Natural History). During the latter part of 1954 the approval of the G.'P.O. and the Museum * A publication of the British Trust for Ornithology. + The last preceding report was published in British Birds, vol. xlvii, pp. 361-392. 461 462 BRITISH BIRDS [VOL. XLVIII authorities was obtained for the use of the shorter address: "BRIT. MUSEUM LONDON S.W.7." to be introduced on rings issued in 1955. Rings inscribed "BRITISH MUSEUM NAT. HIST. LONDON" will remain in circulation for some time. Miss E. P. Leach continued to handle the reports of birds ringed abroad and recovered in Britain- Her advice and ready help on many occasions is gratefully acknowledged. FINANCE The salaries of the Secretary and his assistant were met by grants from the Nature Conservancy. Despite a sharp rise in the wholesale prices of rings the cost to ringers remained unaltered, and the Trust made an increased grant of £150 from its main fund towards running expenses. The full accounts for 1954 appear in the Annual Report of the Trust. PROGRESS OF RINGING The steady increase in the numbers of birds ringed was con tinued in 1954 when the annual total exceeded 100,000 for the first time (see Table 1). Despite a rather poor breeding-season the number of nestlings ringed, 36,621, was the second-highest annual total. At 66,237 the total of birds trapped was an increase of less than three thousand on the 1953 figures, the smallest annual rise since the war. Many more Blackbirds were trapped than usual, partly as a result of the prolonged season and of the marked immi gration of this species in early November when east coast observatories were catching large numbers. Waders and warblers were trapped and ringed in greater abundance and variety than ever before, and the total of sixteen Barred Warblers vies for comment with twenty-one Jack Snipe and seven Little Stints. In all, birds of 209 species and sub-species were ringed during the year, the following nine being new to the ringing list: Red-necked Grebe and Temminck's Stint (Monks' House B.O.); Siberian Thrush, Turdus sibiricus (Isle of May B.O.); Pied Wheatear (John Ash); Aquatic Warbler (Cley B.O.); Arctic Warbler, of the race Phylloscopus b. borealis (Fair Isle B.O.); Yellowthroat, Geothlypis trichas (Lundy B.O); Yellow-headed Wagtail, Mota- cilla citreola (Fair Isle B.O.); and Pine Grosbeak (Isle of May B.O.). The Siberian Thrush, Yellowthroat and Yellow-headed Wagtail were new birds to Britain. Twenty-four individual totals exceeded 1,000, the eleven bird observatories accounting for over a quarter of the birds ringed during the year. RECOVERIES An extra column has been added to Table II showing the numbers of recoveries reported during 1954. There are so many that it is impossible to publish more than a small proportion of VOL. XLVIII] REPORT ON BIRD-RINGING FOR 1954 463 them, and it has been found necessary this year to extend the system of summarization. As an additional help maps have been introduced to show the recovery localities of certain species. Each year produces its quota of unusually interesting recoveries, and in a number of cases comment on a particular bird has been inserted in the recovery list. The restrictions of space must limit such comment, but attention may also be drawn to the Red-backed Shrike in Sicily, two recoveries in France of winter-trapped Great Tits, long- north-westerly movements of Redstart and Spotted Fly catcher on spring passage, a Swallow (ringed at Oundle) in Germany, Sedge Warbler and Willow Warbler ringed at the Isle of May on spring passage and recovered shortly afterwards in Westmorland and Derbyshire respectively, and a Blackbird ringed at Spurn 6th November reported four days later in Germany.
