By collecting careful notes on the appearance, residence on our coasts, and departure from different stations, much might be learned of the reason why some northern species remain to breed some seasons more than others, or remain longer resident into the summer months. Alcidæ.--Puffins, Guillemots, "Tysties," "Rock Birds," etc., Razorbills.--In April, a flock of 100 Puffins fishing around Rhinns of Islay on 3d, and twelve Tysties or Black Guillemots on 10th, "floating in the sound." In May, Tysties at Lochindaul on the 20th, and Puffins--twenty--flying west on 2d, at Kyleakin. In June, great numbers all day of Razorbills fishing around Lochindaul. In August a few all day on 28th at same place. In September, one young Tystie on 15th at Dhuheartach, "eating fish on the rocks." In October on 19th and 21st _continuous flocks_, 6 to 10 A.M., N., light, clear, flying south. This "rush" of sea birds is almost as sudden and remarkable as that of our land birds this year. A few still found in December at Skervuile. No notices South of Clyde. ============== WEST COAST OF ENGLAND AND WALES, AND THE ISLE OF MAN.
