Mixed Diglossini, Aug. 5, 1965, V.  (106)

^[[Laf Ater]] 8:44. Laf supplants and chases [[underlined]] Ater at least three times in rapid succession. [[/underlined]] Both birds silent throughout. This dispute began when Laf flew to attack Ater approximately 8-10 ft away. As far as I could tell, the Ater did nothing "positive" to provoke the attack.

^[[Cinn Laf]] Cinnamon flies into favorite Laf bush [[underlined]] when [[/underlined]] Laf is not there. The Cinnamons seem to be [[underlined]] very [[/underlined]] careful to avoid the Laf.

^[[Cinn Ater]] Cinnamon Swoops at Ater 8:58. Both birds silent. 

^[[Ater]] 9:10. One Ater repeatedly supplants another. Supplants with R's, R-Zaza's, and [[underlined]] R-Twitters [[/underlined]]!

^[[Ater]] Back to Cy side garden. See both adult and juvenile Aters feeding in bush with small white flowers. But not simultaneously. 

^[[Cinn Ater]] Cinnamon perches in the tree with small yellow flowers. Then single Ater flies in. Feeds on flowers only a couple of feet from Cinnamon. The two birds ignore one another.

^[[Ater]] Then I see [[underlined]] 2 [[/underlined]] juv. Aters feeding in bush with white flowers. And an adult also flies in and lands there. Then adult chases and supplants one of the juveniles. Both juvenile and adult fly away.

^[[Ater]] The behavior of the Aters here [[underlined]] may [[/underlined]] tend to confirm one aspect of behavior which I thought I established near Quito. Juvs and adults of Ater seem to associate with, or encounter, one another more frequently than juvs and adults of any other form of Diglossa with which I am familiar.

^[[Ater ?]] Remaining juvenile Ater in bush with white flowers repeatedly ignores [[underlined]] tiny [[/underlined]] greenish hummingbird feeding same flowers only a few inches away. I.E. small birds do [[underlined]] not [[/underlined]] provoke the hostility of Aters.

^[[Ater]] 9:35 am. Now a juv. and an adult Ater are both feeding in bush with white flowers. [[underlined]] No [[/underlined]] sign of overt hostility. Then adult flies.
