Tangara, Sep. 1, 1958, I [circled] 22 [/circled]

[[/left Margin]] 3 vertical green lines, 1 vertical cross-hatched line[[/left margin]]

Sitting rather alert, with lots of flicking, or hopping about, in the top of a Cecropia. Uttered a lot of very distinctive single notes, very nasal, "Auh." Also a few ordinary CN's, especially when moving about. Then flew off. These "Auh" notes sounded or looked almost as though the bird were trying to call in a mate. But didn't get any response. 

There seems to be no doubt but that the green has a more elaborate vocal repeating than any of the other Tangara tanagers I have watched. Presumably primitive. Presumably correlated with the very slight development of gregariousness.

Another adult bird gave a few "Auh" notes while feeding in a Cecropia, but this time its presumed mate was present in the neighborhood - although in an adjoining tree a few feet or yards away.

It is my suspicion that here, at the top of the mountain, the greens only feed and move in the tops of the trees. While the Silver-throats feed and move at both the top and medium levels.

[[left Margin]] two yellow question marks, 1 yellow vertical cross-hatched line[[/left margin]]

I was watching a flock of Silver-throats feeding in the very top of a very high tree, when I heard a definite WS - like that of the green described above on p.21, but even more "whispery" in quality - coming from that direction. I think this may well have been given by a Silver-throat, but I never actually saw the performing bird.

I watched a young bird - very young, probably just out of the nest - FB from its parent. Just as before but even more extreme. Extreme H posture, wings very droop
