66 AUDOUIN'S GULL. 



beak. The number of the bands evidently depends upon the season, 

 as it is impossible to ignore the testimony of the many distinguished 

 men who have mentioned two. 



The young of the year have generally a plumage more or less 

 tinged with many shades of ash and brown; the mantle brown, 

 irregularly spotted with clear brown and russet; and the tail more 

 or less spotted with black and brown. In their second moult in 

 autumn they assume some grey traces on the head and neck; but 

 after their second moult in spring the plumage is perfect. 



My figure of this bird and its egg are from specimens kindly 

 lent to me by Lord Lilford. 



The bird has been figured by Temminck and Laugier, pi. col. 

 480, adult in spring plumage; Gould, B. of E. pi. 438.
