Report on the Immigration of Summer-residents in the Spring 

 of 1913 ; also Notes on the Migratory Movements and 

 Records received from Lighthouses and Light-vessels 

 during the Autumn of 1912. By the Committee 

 appointed by the British Ornithologists' Club (forming 

 Vol. XXXIV., Bull. B.O.C.). 19 Maps. Witherby & Co.

This is the ninth and last but one of the annual Reports 

 of the Migration Committee of the British Ornithologists' 

 Club. The number of records again shows an increase, 

 and this year the Committee has been fortunate in obtaining 

 much information from the Caskets Lighthouse (Channel 

 Islands) — an important point. The winter of 1912-13 was 

 remarkable for the number of summer birds which appear 

 to have passed the winter with us. In addition to those 

 already recorded in our pages (c/. Vol. VI.), the following 

 are mentioned in this Report : — Chiffchaff {Ph. collyhita), 

 Scilly Isles, one or two heard January ; Willow-Warbler 

 [Ph. trochilus), Hampshire, one end of January ; Ring-Ouzel 

 {T. torquatus), one Carmarthen, middle of February ; Whinchat 

 {S. rubetra), Yorkshire, one January 3rd ; Turtle-Dove 

 {S. t. turtur), Scilly Isles, one February 28th. Swifts {A. a. apus) 

 staj^ed late in several districts in the autumn of 1912. Summer 

 immigrants seem also to have arrived early in the spring of 

 1913, so that it is difficult to say in some cases whether an 

 occurrence at an exceptionally early date refers to a bird 

 which had wintered here or to one which had immigrated 

 here perhaps from no great distance. Some of the following 

 may come under either denomination : — 



Pied Flycatcher {M. h. hypoleuca), Lancashire, April 

 3rd ; Chiflfchaff, Hampshire, February 25th, Cornwall 

 and Cumberland, February 28th ; Willow- Warbler, Scilly 

 Isles, March 9th ; Garden- Warbler {S. horin), Kent, March 

 25th ; Wheatear {(E. oe. oenanthe), Suffolk, March 6th ; 

 Greenland Wheatear {(E. oe. leucorrhoa), Channel Isles and 

 Isle of Wight, April 13th; Whinchat, Wiltshire, March 

 13th ; Swallow {Ch. r. rustica), Scilly Isles, March 6th ; 

 Nightjar (C. e. europceu^), Yorkshire, April 6th ; Turtle-Dove, 

 Berkshire, April 7th, Channel Isles and Suffolk, April 8th ; 

 Common Sandpiper {T. hypoleuca), Lancashire, March 5th ; 

 Common Tern (S. h. hirundo), Argyll, March 22nd. A 

 Fieldfare {T. pilaris) in Kent on September 16th, 1912, and
