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. 1 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.
