Bulletin of the British Ornithologists' Club. . 1956 37 Vol. 76 y BULLETIN OF THE BRITISH ORNITHOLOGISTS' CLUB Volume 76 Number 3 Published: 1st March, 1956 The five hundred and forty-sixth meeting was held at the Rembrandt Hotel, South Kensington, on Tuesday, 21st February, 1956, following a dinner at Chairman: Mr. E. M. Nicholson. Members present: 27; Guests 5; Guest of the Club: Mr. I. C. T. Galbraith; Total: 33. Possible Irradiation in Birds Dr. James M. Harrison exhibited a second Redshank showing incipient summer plumage in winter. Minimal signs of radioactive contamination was found by Dr. John Loutit's department at Harwell and a graph demonstrating this was shown to members. Dr. A. J. Marshall reported on the ovary and oviduct that the development was rather in advance of what he would have expected in a normal wintering bird. While the full significance of these findings must await controlled experiments, it was felt that they should be placed on record and a paper will appear in a subsequent Bulletin. The Birds of San Cristoval, British Soloman Islands Mr. I. C. T. Galbraith gave a most interesting talk illustrated by slides of his recent expedition. He stated that the avifauna has close affinities to that of New Guinea, and described the various habitats, stressing the remarkable geographical variation. This included repression of sexual dimorphism in certain species and size variations affecting both general and regional characters. He stressed the probable different geological origin of San Cristoval and Guadalcanal, the thirty miles separating them representing a faunal break. Guadalcanal has 95 species, San Cristoval 72, but there are only 36 forms common to Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Taylor, Nancy M.
