The Short-toed Lark 



name indicates, the hind claw is short. The under parts are 

 white and unspotted except for a few streaks on the sides of 

 the neck. Length 5 '5 in. ; wing 3 '4 in. 



THE WHITE-WINGED LARK 



Alauda sibirica, J. P. Qmelin 



This species breeds across Central Kussia and through 

 the Kirghiz steppes as far as the Altai, migrating southwards 

 in winter. Has only once occurred in England. The bill 

 is short and stout, and this species may be at once recognised 

 by the white inner primaries and secondaries, which form a 

 conspicuous patch. Length 7*5 in. ; wing 4*6 in. 



THE BLACK LARK 



Melanocorypha yeltoniensis (Porster) 



This species inhabits South Eussia, Transcaspia, and 

 Western Siberia. In the winter of 1906 a small flock, 

 consisting of both males and females, arrived in Sussex, 

 being presumably driven westwards owing to the severity of 

 the weather. 



The male has the entire plumage jet black, but in winter 

 this colour is largely obscured by broad sandy margins to 

 the feathers. The female is pale sandy brown with darker 

 markings, under parts white, spotted on the throat and 

 breast. Length about 7 '7 in. ; wing 5 '3 in.
