Foreign Thrush-Like Birds.

T think there [can be no doubt that the colour difference which 

 enables the birds to distinguish each other, consists in the sulphur 

 yellow of the elliptical patch enclosing the eye of the male, which 

 in the female is ashy or pale creamy whitish ; however, I recommend 

 all who want to get a cock bird to whistle the monotonous call of 

 the hen until some bird replies with the little warbled phrase which 

 represents the cock's reply to his mate ; and let them see that they 

 get that bird and no other ; they will find it far more certain than 

 if they selected the brightest and dullest out of five hundred or 

 more individuals. 



The Bulbuls. 



These charming songsters among the Thrush-like birds are easy to 

 sex by the form of the bill ; that of the male, unlike the bill in the 

 true Thrushes, being stronger, shorter, and with slightly more arched 

 culmen (ridge) than in the female.
