Tangara,
Sept 19, 1958, I 

I have only once or twice seen it associated with the mixed flocks of Bush-tanagers, warblers, finches, etc. Usually ignores the flocks while it feeds by itself, even in the same general areas as the flocks. 

Tangara, I.       
October 31 1958
Brown Zoo

Among the many Callistes they have here now is a single (♂?) Yellow-headed Tanager = xaultiocephala = [[orange color swatch]]. In a small cage with a lot of other Callistes and other birds

Seems to move about like all the other tanagers of the same genus. Same WF's and TF's.  The only CN's I have heard are weak ordinary "Frits" - and they seem to be relatively rare (although this is difficult to tell, as it is difficult to hear sounds from this cage.)

I have noticed that it assumes quite a definite stretch posture as an int. mov. of flying up.
More or less like this. [[drawing of bird]]  Possibly more extreme at times.  Probably unritualized?

Once, when a golden-mask came too close, the Yellow-head did a definite G, from a quite unritualized posture

Actually, I don't suppose that this pre-flying stretch is any more exaggerated than that of most other tanagers.  Quite possibly less than that of many species
