[[margin, in red]] 8 [[/margin]] Then the Hummers ^[[two check marks]] ^[[two red check marks]] fly away, separately. No one follows. Then the [[underlined]] nigrocristatus [[/underlined]] ^[[two pencil and two red checkmarks]] go down hill. Apparently no one follows them either. Throughout the period I watched this flock, the [[underlined]] nigrocristatus [[/underlined]] showed a definite tendency to stick to bamboo. The White-bearded flycatchers showed a preference for small, ordinary trees. Both the warblers and flycatchers ranged 5 - 10 ft above ground. 8:45 am. A single Firebelly flies by. Definitely alone.

The flock seen above Griusca this morning was really [[underlined]]incredibly like [[/underline]] the flock(s) seen in the same area in 1962. Almost all the same species involved. And the species apparently playing much the same roles. I was struck (again) this morning by the fact that the mix
