Mixed Diglossini, Sept. 18, 1962, III                      

overhead), there are apparently no Diglossini.

[[left margin]] Gen [[/left margin]]
10:30 am Have now walked a long way. Reached approximately 8500 ft. (uncorrected). Absolutely no sign of any Diglossini after the first "pocket". Not even when there are trees around. Probably because there are relatively few suitable flowers around. (Flowers are remarkably scarce here now.)

Passing the pocket 12:00 noon.  No diglossini visible yet. 

Start on path going down below station 1:55 pm.
[[left margin]] Albi [[/left margin]]
2:20 pm. Come across an area where there are quite a lot of a variety of CN's and similar notes. Apparently a mixed flock but not very well integrated. Most of birds impossible to see. But certain one slate-throated Redstart, 1 largely bright blue tanager or honeycreeper of some sort, some hummingbirds. And one Albi!! (This is several hundred feet below where I saw the Albi with the mixed flock a couple of days ago.) Feeding on pink flowers of vine half way up a tree. About 30 ft. above ground. Apparently piercing flowers in usual Diglossa way. Quite silent. Flies off almost immediately. Rest of group disappears about the same time or shortly thereafter.

I am almost certain that this Albi became involved in some apparently hostile chasing with another bird of another species (probably the blue honeycreeper type). If so, the Albi was the aggressor and chased the other off.

Albi may be the dominant form in this region. The equivalent of  aterrinia near Quito???

Albi may be able to associate with mixed flocks more often than most Diglossini because it consumes a relatively large amount of insect food?
