The red-billed pie is not known to occur in Chiang Rai but is 

 rather common in all the other provinces, haunting deciduous forest 

 and scrubby second growth, from the plains to about 2,700 feet. 



This fine bird is shy and avoids the vicinity of human habitation 

 but may often be seen in dry jungle and at uncultivated places along 

 the rivers in flocks of five or six individuals, which follow each other 

 from tree to tree uttering harsh, scolding cries. It often descends to 

 the ground to feed and drink and then carries the exaggerated tail 

 somewhat erected to keep the longest feathers, which naturally curve 

 downward near the tip, from becoming soiled. 



Specimens that have almost completed postnatal molt were taken 

 in southern Nan Province on May 25 and 30. An adult from Mae 

 Hong Son Province, October 23, is in postnuptial molt. 



De Schauensee notes (1929) that a male had the irides brown; the 

 bill bright sealing-wax red; the feet, toes, and claws bright coral red. 



The adult has the head, neck, and upper breast black, with a large 

 and conspicuous white patch from the center of the occiput to the 

 center of the uppermost back ; the scapulars, back, and rump dull blue- 

 violet; the upper tail coverts blue-violet with broad, black tips; the 

 wings deep violet-blue, both primaries and secondaries more or less 

 broadly tipped with white; the strongly graduated tail deep violet- 

 blue, each feather with a broad, white tip and all except the central 

 pair with a broad, black, subapical bar; the remaining underparts 

 bluish white, bluer on the lower breast, upper abdomen, flanks, and 

 thighs. In freshly molted examples, the central part of the outer
