Mixed Diglossini, Sept.19, 1962, VII

[[left margin]] Glor  Albi [[/left margin]]
of Glor or Glor-type singing in distance. For a while, 2 or 3 Glor or glor-type warbles alternate with 2 or 3 Albi R's quite regularly. Then glor or glor-type bird shuts up. Albi(s) continue uttering R's. 

[left margin]] Albi  Cy [[/left margin]]
Now that I recognize "song" of Albi, I hear it very frequently. Albi (including Buff-throats) must be by far the dominant species here. Much commoner than cyanea.

[[left margin]] Albi [[/left margin]]
The adult ♂ Albi I watched singing very high in the tree also fed on tubular flowers at same level between R's. 

I shall use the terms "R" and "song" interchangeably in the case of the adult ♂ Albis and Buff-throats here.

Then the rain comes down again.

Starts to stop. Then, 1:15 pm. On the far side of the "pocket", (ie. on the opposite side from A Glor area) I suddenly come across a huge mixed flock. In thickets and in a tree, covered with flowering vines, reaching a height of about 50 ft. Flock includes 4 or 5 BCBT's, at least 1 Thraupis cyanocephala, hummingbirds, others. Also 1 Glor and 1 adult male Albi. Both Diglossas feeding on same flowers. But I don't think they came in contact with one another. First the Glor came, fed, and then left. Then the Albi came, fed, and also (I think) left. Both quite silent throughout. So they seem to be able to maintain specific separation even when they join the same flocks. 

This area was really inside forest, but near edge. Not far from another area with dense thickets but no trees like the A Glor area.

[[left margin]] Albi [[/left margin]]
Flushed a single adult ♂ Albi from a thicket 1:55 pm. In an area that looks rather like Glor habitat (altho I haven't seen any Glors here). At 8050 ft, the highest I have seen Albi yet.
