Mixed Diglossini, Apr. 6, 1965, III  

Fog coming in 4:35

Good heavens! What appeared to be a ♂ American Redstart flew into a Eucalypt, stayed a second, and then flew out again.

[[margin]] BQ Bari [[/margin]]
One BQ finally shows up in usual Erythrina, 4:44. Feeds briefly and silently. No other diglossine around at the time. Leaves. Then a ♀ Bari shows up and feeds in another part of the tree. She repeatedly supplanted by an Andean Sparrow. Finally flies off.

[[margin]] Bari XCC [[/margin]]
♀ Bari back a few minutes later. Looks around cautiously in semi-hunched posture. Silent. No other diglossine around. Then she begins to feed. Then an XCC lands in branch about 10 ft away. Also begins to feed. The two birds apparently ignore one another. Then the XCC flies to a branch 2-3 ft away from Bari. XCC apparently begins to feed again, right away. ♀ Bari immediately stops feeding, looks at XCC for a couple of seconds. Then flies away. Both birds silent throughout. This would suggest that XCC's "repell" ♀ Baris. Possibly also that XCC's are "dominant" over ♀ Baris. See below.

[[margin]] Gen [[/margin]]
5:05 Fog so thick that is it impossible to see. Leaving

It looks as if there may be a hierarchy among the diglossines here: BQ > XCC > Bari

[[margin]] Gen [[/margin]]
It was my impression, this afternoon, that the ♀ Bari visited the Erythrina I was watching more frequently than usual. Was this due to the fact that the BQ's, and the XCC, visited the tree less frequently than usual.

[[margin]] Albi [[/margin]]
NOTE: The fact that there was a ♀ Albi at Paramo La Negra this morning would suggest that the Albi — like songs heard there in 1962 were in fact actually uttered by an Albi. As I remember,
