I think that all these birds must be classed as belonging to a flock. Including the Brown Whitestarts. Latter probably only "transient" members of group. But the rest may be highly integrated. No obvious leadership. Cheek Atlapetes noisy. Other species fairly quiet.

Rain is so bad now that I have to turn back.

About 100 yds down road, come across pair of birds. Apparently Brown Whitestarts. Almost certainly same individuals seen a few minutes earlier. Again one is flycatching from ground while the other flits thru scrub. About 10 yds away I see 2 Cheek Atlapetes, 6 - 10 ft up in small trees. Certainly [[underline]] not [[/underline]] the same individuals seen earlier. The two species apparently ignore one another. And move in different directions. Thus, I think that they should both be classified as [[underline]] alone. [[/underline]]

COMMENT: I have no idea what CXXX really is. Whitestart (adult or juvenile), flycatcher, or what have you. But it probably was what I called "Slate throat" yesterday. If so, the role of the species (or form) in mixed flocks seems to be fairly clear (on my observations so far). An occasional associate. Occasionally joining and/or joined by other birds; but not sticking with them. And, I should add, that I have never seen it [[underline]] close [[/underline]] to a Whitestart CXXVII when the two species are associated in the same flock. All very reminiscent of the relations between the two species of Whitestarts at the Farallones [best gues]] above Cali!

NOTE: It is very general impression that the avifauna
