Then see 3 [[underline]] cyanocephala [[/underline]] alone in tree top.

COMMENTS:
I. All in all, I don't think that the social behavior of most of the birds here has changed very much since September of 1962. Probably one of the reasons I have seen very few well-integrated, closely-knit, mixed flocks this year is that I have seen very little of the [[underline]] luteoviridis [[/underline]] - types and nothing of the gray-headed [[underline]] Basileuterus. [[/underline]] These may be the only two species which "inspire" the formation of close flocks.

II. As far as my observations this year go, they confirm my earlier impression that there are really two types of mixed flocks here: "tree-top" and "bush."

In my final report, I will be able to discuss and compare only the "bush" flocks in detail. I shall ignore the "tree-top" flocks as much as possible.

Of the species observed at some length during this trip, probably only [[underline]] cyanocephala [[/underline]] is a frequent member of "tree-top" flocks. (Of course, it also occurs in "bush" flocks.)
