26 How to Sex Cage Birds. 



The Waxwings (Ampelidas). 



After careful examination I failed to discover any appreciable 

 difference in the bills of male and female ; if any exists, the male 

 bill is possibly a trifle heavier than that of the female, but one may 

 look too long for a character, and perhaps imagine its existence in 

 the end ; anyhow, there is no difference worthy of consideration. 

 The tips of the tail feathers in the female are somewhat narrower 

 than in the male, and the wax-like terminations to the secondaries 

 are smaller. 



The Common Waxwing (Ampelis garrulus). 



The female is duller than the male, and generally without white 

 tips to the inner webs of the primaries. 



Flycatchers (Muscicapidai). 

 The females have a rather more slender bill than the males. 



The Spotted Flycatcher (Muscicapa grisola). 



The sexes are much alike, but the female is perhaps somewhat 

 browner and more heavily streaked below than the male. 



The Pied Flycatcher [Muscicapa atricapilla). 



The female is browner above than the male, and the white 

 portions of the plumage are stained with buffish. 



The Red-breasted Flycatcher [Muscicapa parva). 



In the female the rich orange-chestnut throat is replaced by buff, 

 and the bluish-grey is absent from the head and sides of neck. 



Swallows (Hirundinidce). 



The females are rather smaller than the males, but I can find no 

 constant difference in the bills. 



The Chimney Swallow (J/irundo rustica). 



The female has the outer tapering tail-feathers shorter than in 

 the male; the colouring very slightly duller, the under parts 

 generally whiter, and the breast-belt narrower. 



The House-Martin (Chelidon urbica). 

 No colour difference in the sexes has been noted. 



The Sand-Martin (Cotile riparia). 

 The female has a narrower belt across the breast than the male.
