Old birds in perfect color have the forehead bright greenish yellow, 

 changing to bright yellow-green on the crown and crest; a broad, 

 black band across the nape and continued on either side of the head, 

 through the eye, to the base of the bill ; the scapulars, back, rump, and 

 upper tail coverts glaucous-green ; the wings bright chestnut-red, the 

 inner secondaries with a broad, white tip and a broad, black, sub- 

 terminal bar; the rectrices glaucous-green, all with a broad, whitish 

 tip and all but the central pair also with a broad, black, subterminal 

 bar ; the entire underparts light glaucous-green. 



Apparently as a result of exposure to sunlight, yellow disappears 

 from the plumage, the green portions change to light blue, and the 

 chestnut-red of the wings becomes gray-brown or even olivaceous- 

 gray. Most specimens, while still alive, show such alteration, and the 

 change is more pronounced in birds taken just before the molt and in 

 those few collected in hot, dry forest with little shade.

The Peguan rufous tree pie dwells in exactly the same types of jungle 

 as Kitta e. magnirostris but has a much more restricted range : within 

 our provinces it seems to be confined to the lowlands of the Mae Ping 

 basin and, in addition to the localities listed above, has been taken 

 only at Ban Mae Dok Daeng, Chom Thong, Ban Sop Mae Chaem, and 

 Ban Pa Pua. On Doi Suthep I once saw a solitary straggler at 3,000 

 feet (August 23, 1930), but otherwise it has never been found above 

 1,500 feet. 



This pie lives in the dry forest in small bands, the members of which 

 follow one another from tree to tree with alternate sailing and beating 

 of wings, constantly uttering a rather musical trisyllabic call as well as 

 many harsher notes. It is one of the forms that make up the mixed 

 bands of Kitta, GarrvZax, Dissemurus, etc. One of my specimens had 

 the stomach filled with large berries.
