ii6 THE BIRDS OF DORSET. 



COMMON GUILLEMOT. Uria iroile, (L.) 



YarreU, iv. p. 69; Harting, p. 74; Alca troile, Dresser, viii. 

 p. 567; Seehohm, iii. p. 388; Lomvia troile, Ibis List, 

 p. 206; Colymbus troile, Pultenei/'s List, p. 17. 



During the breeding season the Common Guille- 

 mot resorts to our cliffs in some numbers, depositing 

 a single egg upon a ledge of the rock, without any 

 attempt at a nest. After the breeding season both 

 old and young go out to sea, and are not seen in the 

 cliffs during the winter. The Einged or Bridled 

 Guillemot, which has a white line round and behind 

 the eye, once thought to be a distinct species, is now 

 considered to be only a variety of Uria troile. Two 

 were picked up after a storm in Christchurch Bay, 

 with a considerable number of the ordinary type. 



A singular variety of this bird, having the bill and 

 legs yelloiv, was shot by Mr. T. M. Pike near Poole, 

 November 29, 1876 {Zoologist, 1877, p. 57). 



BLACK GUILLEMOT. Uria grylle, (L.) 



YarreU, iv. p. 81 ; Ilarting, p. 74; Dresser, viii. p. 581 ; Ibis 

 List, p. 207 ; Alca grylle, Seehohm, iii. p. 383 ; Colymbus 

 grylle, Pulteneijs List, p. 1 7. 



The Black Guillemot, as YarreU states, is occa- 

 sionally procured on the coast of Dorsetshire, but 

 must be regarded as a rare visitor. Mr. H. Groves 

 has one which was shot in Weymouth Bay in the 

 winter of 1855. Another was killed at Swanage 

 Bay in January 1862 (E. Hart), and a third in 

 Weymouth Bay, December 10, 1874. Since then.
