Foreign Thrush- Like Birds. 17 



The Collared Jay-Thrush (Garrulax picticollis). 



There appears to be no constant sexual difference in the plumage, 

 so far as I could judge by an examination of skins, and I have 

 only possessed a living male. 



In Dryonastes the bill of the female is shorter than in the male, 

 but I could detect no appreciable difference in "width. 



The Black-throated Laughing-Thrush {Dryonastes chinensis). 



I could discover no reliable sexual difference in the plumage. 



In Trochalopterum the female is decidedly smaller than the male, 

 and its bill is shorter and a trifle more slender. 



The Chinese Spectacle-Thrush (Trochalojrtemom canorum). 



The bill of the hen is paler and the throat more brightly coloured 

 than in the cock bird. 



Other Thrush-like birds are occasionally imported, but too rarely 

 to render it necessary to consider them in the present treatise.

 BRITISH WARBLERS AND ACCENTORS. 



Unlike the true Thrushes, the sexes of Warblers (Sylviince) do not 

 differ appreciably in the width of their bills, but only in the length, 

 those of hen birds being noticeably shorter than those of cocks ; both 

 have slender bills. The male is slightly larger than the female. 



The Greater Whitethroat (Sylvia cinerea). 



In colouring the female can be distinguished from the male by 

 the lack of the grey head and upper tail - coverts, and the faint 

 vinous tint on the breast characteristic of the male summer dress. 

 In the winter the sexes are far more alike, so that at that season 

 the structural differences must be relied upon. 



The Lesser Whitethroat (Sylvia curruca). 



The female is a trifle duller in colouring than the male, but its 

 smaller size and shorter bill are its most trustworthy distinctions. 



The Blackcap (Sylvia atricapilla). 



The hen differs from the adult cock in its rufous brown cap and 

 in its generally browner summer plumage. Young cocks nearly 

 resemble the hens in colouring, but a stouter bill, characteristic of 

 birds which have not been for many months out of the nest, should
