214 BIRDS OF BRITISH BURMAH. 



The female has the forehead white streaked with black ; the crown, nape, 

 upper back and sides of the neck bright chestnut ; the hinder part of the 

 ear-coverts also tinged with chestnut; the remainder of the plumage 

 similar to the male. 



Cere, gape and both mandibles as far as the nostrils orange-yellow ; 

 anterior portion of bill bluish black; eyelids and orbital skin orange; 

 iris brown ; legs orange ; claws black. 



Male: length 1O5 inches, tail 5*5, wing 5*5, tarsus 1*5, bill from 

 gape '75. Female : length 11, tail 5'8, wing 6, tarsus 1*6, bill from 

 gape '75. 



This beautiful Falcon was almost simultaneously discovered by Capt. 

 Feilden at Thayetmyo and by Colonel Lloyd at Tonghoo. It is very 

 abundant at the former place, extending on the west to the crest of the 

 Arrakan hills ; but at Tonghoo, according to Capt. Wardlaw Ramsay, it is 

 rare. I never observed it in any portion of Central or Southern Pegu. 

 Mr. Davison noticed it in Tenasserim, from Myawadee down to Mooleyit 

 mountain; and Capt. Bingham procured a series in the Thoungyeen 

 valley. 



Mr. Gurney informs me that he has seen a specimen from Western 

 Siam. 



This Falcon is generally found in clearings in the dry forests so abundant 

 in Northern Pegu. It feeds almost entirely upon insects. I have never 

 found its nest ; but from what Capt. Feilden observed, it appears to breed 

 in March and April, and its nest is placed in trees.
