LESSER TERN.— (Mature.) 



Case 257. 



During tlie last fifteen or twenty years this graceful 

 little bird has entirely disappeared from several of its 

 breeding-stations in the south of England. 



There are, however, still numerous localities where 

 it may yet be found, though, I am afraid, in rapidly 

 decreasing numbers. 



The specimens in the case were shot at Rye, in 

 Sussex, in May, 1860. 



GREEN WOODPECKER.— (Matuee & Immature.) 



Case 258. 



The hissing and snapping noise emitted by a brood of 

 young Woodpeckers, when in the nest, would most pro- 

 bably deter anyone unacquainted with their note from 

 exploring the hole in which they were concealed with- 

 out due caution, as the sound would hardly be thought 

 to proceed from a bird. 



The specimens in the case w^ere obtained in Bal- 

 combe Forest, in Sussex, in June, 1875. 



At this early stage (the day the young first left the 

 nest) it is already possible to distinguish the sexes, 

 the black mark under the bill of the male containing a 

 few red feathers, while that of the female is plain.
