92 How to Sex Cage Birds. 



the sexes of the Larks, apart from any other characters which may 

 exist. The length of the hind claw is said to differ sexually. 



As in the Zoological Society's List and Howard Saunder's 

 Manual, as also in British Birds, with their Nests and Eggs, I have 

 left this family next to the Crows, although its relationships are 

 rather with the Pipits and Finches. 



Common Skylark (Alauda arvensis). 



The sexes do not differ in plumage, but the female is smaller, and 

 has proportionately shorter wings, the average length of the male 

 being 7 inches, and its wing i-}, inches; that of the female 6£ 

 inches, and its wing 4^ inches.

Indian Skylark (Alauda yulyula). 



In addition to its slightly inferior size, much shorter wing, and 

 slightly shorter tail, the female differs from the male in its dusky 

 claws and darker eyes. 



Dr Sharpe considers the Sweet-voiced Lark (Afauda aclivox) to 

 be simply a pale Chinese race of the Indian Skylark ; he has 

 removed the Woodlark and Crested Lark from the genus Alauda 

 to Lidhda and G'alerita, but has not been generally followed in the 

 case of the Woodlark. 



Woodlark (Alauda arborea). 



The sexes differ very slightly in size, but the average length of 

 the wing in the female is decidedly shorter. 



Crested Lark (Galerita cristata). 



The female resembles the male in plumage, but is smaller, and 

 has a much shorter wing.
