Mixed Diglossini, Aug. 6, 1965, VIII.   (116)


Feeds. Flies on

^[[Ater VB]] Look up a few minutes later, to see both Ater and VB feeding in TI. At least 8 ft apart. VB flies off. Ater does [[underlined]] not [[/underlined]] follow. Flies away a couple of minutes later, in opposite direction.

^[[VB Ater]] 8:58 am. VB back in TI. Alone. Then Ater flies in. Lands at least 10 ft from VB. But VB flies off right away! Ater flies off a minute later.

^[[Ater Cinn ?]] Ater back almost immediately. Silent. Alone. Cinn appears. Perches adjacent tree. Then SGH appears! Lands 6 ft from Ater. [[underlined]] No overt reaction between the two birds! [[/underlined]] Then a second Ater appears in TI. The first chases the second. Long twisting aerial flight. Aters pass near SGH - which flies off immediately. All 3 birds disappear.

Leaving 9:05 am.

COMMENTS:

I. The relations of VB with Cinn and Ater might be summarized as follows:

^[[VB Cinn Ater]] Cinns do "attack" VB's. But not very frequently. And VB'S show better or no reluctance to come to the feeding tree when Cinns are actually in the tree itself or very close nearby.

Aters may also "attack" VB's. But apparently even less frequently than Cinn's.

Nevertheless, VB's [[underlined]] are [[/underlined]] reluctant to come to the feeding tree when an Ater is in it. (Thus would suggest that attacks by Aters, although less frequent, are apt to be more [[underlined]] damaging [[/underlined]] than attacks by Cinn's.)

Aters certainly are [[underlined]] not [[/underlined]] reluctant to come to the feeding
