Mixed Diglossini, Aug. 5, 1965, VI.  (107)

away.

^[[Ater ?]] Speak of the devil! [[underlined]] Adult [[/underlined]] Ater [[underlined]] repeatedly [[/underlined]] (at least 4 times) supplants and chases small green hummingbird. [[underlined]] So Aters do not always refrain from attacking much smaller birds! [[/underlined]]

^[[Ater]] Then hear outburst "Zraah" Notes in bush with white flowers. Catch glimpse of two birds flitting about. Adult Ater chasing juvenile of same species?

^[[Ater]] Then see adult Ater feeding tree with yellow flowers. Silent and alone. Then single Firebelly (!) flies into same tree. Lands about 6 ft from Ater. Silent. Firebelly flies off. Ater does not follow.

^[[VB Ater]] Then VB lands in same tree. Feeds yellow flowers 6-8 ft from Ater. The two birds ignore one another. Ater flies off in one direction. VB in another.

Light rain again 9:45.

^[[Ater VB]] A few minutes later, both adult Ater and single VB back in tree with yellow flowers. Must have arrived almost or exactly simultaneously. Both silent. Again feeding 6-8 ft apart. Then VB flies away. Ater does not follow.

^[[VB Ater]] It has been my impression, both today and yesterday, that Ater and VB [[underlined]] may [[/underlined]] have [[underlined]] slight [[/underlined]] tendency to "synchronize" their visits to this tree. I.E. they are in the tree simultaneously somewhat more frequently than one might expect by chance alone - judging from the general amount of time they spend in the tree, compared with their time away from the tree. Possibly the sight of one feeding attracts the other. There is no reason to suppose that [[underlined]] this [[/underlined]] attraction is hostile (although there is no reason to suppose that it could not be hostile either).

^[[VB Ater]] 10:00 am. Now there are [[underlined]] two Aters and two VB's [[/underlined]] in tree simultaneously!
