[[left margin in red]] Cy [[/left margin]]

Presumably hidden by intervening vegetation. Then I see Cy, 20 ft up, feeding in same tree. Apparently looking for insects. 

[[left margin in red]] Laf [[/left margin]]

I think this Cy cannot be more than 20 ft away from Laf while the latter is Singing. Cy remains silent. Whitestarts (not very close by) also are silent at the time. Then Laf shuts up. I imagine that it probably flies away to another tree or bush. A minute or so later, Cy sings a few phrases. 

[[left margin in red]] Cy [[/left margin]]

Whitestarts still silent, Then Cy shuts up. A minute or so later, Whitestart(s) sing(s) a few phrases. Then shuts up.

Apparently mutual inhibition of song is operative within the Diglossine Social Complex here at this time!

[[left margin in red]] Sitti Laf 14 Cy [[/left margin]]

The Sittis certainly follow flock when it eventually moves off. But I [[underlined]] think [[/underlined]] that the Laf and Cy [[underlined]] do not [[/underlined]]. Some minutes after end of Songs, I see a single bird, apparently Laf, fly in opposite direction from rest of flock. Into low scrub, where it disappears immediately. A couple of minutes after this, I see a single bird, apparently Cy, fly into [[underlined]] same [[/underlined]] bush. Also disappears.

[[left margin in red]] Sitti Laf Cy [[/left margin]]

Sittis and PL's may have much the same relationship to flocks here. While the relationship of Laf(s) and Cy(s) to mixed flocks may be much the same as that of PR's.

This flock eventually disappears downhill. So I go walk along the road a little. At 10:35 am., 500 yds away, I come across a small group of birds which apparently is an entirely [[underlined]] different [[/underlined]] flock.
