THE BIRDS OF NORTHERN THAILAND 275 



PERICROCOTUS BREVIROSTRIS (Vigors) 



Short-billed Minivet

The short-billed minivet has so far been found in Thailand only on 

 Doi Ang Ka and Doi Suthep, between 4,000 and 5,500 feet. It may be 

 expected to occur on all the higher peaks of the western provinces. 



Within its altitudinal range this species occurs in the same places as 

 the preceding bird, from which it is only with difficulty separable in 

 the field. 



I have no notes on the breeding season or the sequence of plumages 

 in the young. Adults in postnuptial molt have been taken between 

 July 14 and October 26. 



My specimens had the irides dark brown; the bill, feet, toes, and 

 claws black. 



The adult male differs from the adult male of the scarlet minivet in 

 its lesser size; in having the red portions of the plumage scarlet- 

 crimson rather than scarlet ; in having the central rectrices black with 

 (in fresh plumage) a very narrow red edging along the outer web on 

 the apical half ; in lacking the elongate spot on the inner secondaries. 

 The adult female differs from the adult female of the scarlet minivet 

 in its lesser size and in lacking the elongate spot on the inner 

 secondaries.
