Mixed Diglossini, July 27, 1965, VII.  (80)

^[[Albi Cy]] The Albis and Cys here certainly do not appear to be stratified in any way. (Of course, the scrub and wood here is so low that there is hardly room for stratification.)

^[[Scan Albi MSGH]] Well! well! well!  8:45 am.  Single Scan (identification definite) appears very close by. No diglossine or other hummingbird around at the time. Scan spends at least a minute, [[underlined]] definitely feeding on purple flowers, same species favored by Albis and medium-small green hummingbird [[/underlined]] (MSGH). Quite silent. The particular bush in which it is feeding is [[underlined]] not [[/underlined]] one of the ones which the Albis visit most frequently; but I definitely have seen [[male symbol]] Albi, one or more Cys, and MSGH in it occasionally.

^[[MSGH Scan]] Then MSGH suddenly appears. [[underlined]] Swoops at, and chases, Scan. [[/underlined]] Attack is silent. [[underlined]] Scan leaves without resistance [[/underlined]]!!!  (Altho the MSGH is [[underlined]] very appreciably [[/underlined]] than it is).

^[[Scan]] Are the Scans less aggressive here than in some other parts of the Andes??? Or is this particular area "marginal" for the local Scan????

^[[Scan]] Scan Songs becoming increasingly brief, and separated by increasingly long periods of silence 8:55 am. Probably the Scans also are past the peak of display now.

I wonder why there are no Whitestarts in this area?  The area looks as if it could support at least a small population.

^[[77 Albi MSGH]]  ^[[checkmark]] 9:08 am. [[male symbol]] Albi back. Silent and alone. Feeding purple flowers 8 ft up. Then there is some kind of rapid hostile encounter between the [[male symbol]] Albi and a hummingbird, probably MSGH. [[underlined]] Hummingbird certainly the aggressor. [[/underlined]]  Apparently swoops at [[male symbol]] Albi. The latter holds its ground, doesn't even flinch. And the hummingbird flies
