220 BIRDS OF BRITISH BURMAH. 



Length about 12 inches, tail 5 '3, wing 9, tarsus I'l, bill from gape *7. 

 The female is of very much the same size, perhaps a little larger, not 

 notably so. 



The description of the adults is taken from a pair shot by Mr. Swinhoe 

 in China, and figured in Mr. Gould's ' Birds of Asia/ 



C. vespertina, the Western form, is similar in general appearance ; the 

 adult male differs in having the under wing-coverts and axillaries the same 

 slate-colour as the abdomen, not white ; the female differs in having the 

 head rufous and the under plumage almost uniform rufous, with no marks 

 except a few black shaft-lines ; the young bird differs in having no bars 

 on. the sides of the body, and the tail has more bars, usually about eleven 

 against eight in C. amurensis. 



The Eastern Red-footed Kestril appears to be a winter visitor to 

 Burmah. Capt. Feilden, the only naturalist who has observed them in 

 Burmah, met with them at Thayetmyo in January and February. 



It is found in summer in North-eastern Asia ; and it winters in Southern 

 Africa, passing en route through India and the Indo- Burmese countries. 



This Kestril is generally gregarious, and it feeds on insects, which it 

 catches both on the wing and on the ground.
