10 ft up. The Yellow bellies and LXXXXI are medium in "elevation" as well as sequence. Range 5 - 20 ft up, in both bushes and trees The PL(s) range 2 - 35 ft up, thru all types of vegetation. 
The 3 Whitestarts definitely bring up rear of group. Tend to stick to second growth scrub, 3 - 5 ft up.
At least once, they fight among themselves.

When flock first appeared, [[green check mark]] [[insert, in purple]] 10 [[/insert]] 1 or 2 Sooty Thrushes went [[underline]] toward [[/underline]] it. And moved rather erratically around its outskirts. But apparently they
did not stay with it. (The behavior of these Thrushes, in fact, was somewhat reminiscent of "escorting" by Diglossa spp.)
The flock passed thru an area where I have seen PR(s) on earlier occasions.

And just as this happened, I saw a pair of PRs [[two green check marks]] [[insert, in purple]] 11 [[/insert]]

other birds. Apparently, however, they did [[underline]] not [[/underline]] [[two red check marks]] follow the flock when it eventually moved on. This is in striking contrast to the behavior of the PL's. The PL's certainly did follow the flock. It is my general impression that PL's are [[underline]] much [[/underline]] more strongly allo-gregarious than PR's. (This may be of some theoretical importance in connection with my hypothesis. The PR's here seem to fill much the same ecological niche as the [[underline]] rufinucha [[/underline]] in the Quito region. If the PR's here are less gregarious than in some other parts of the Andes, such as the Eastern Cordillera - which seems possible - then their behavior may be compared with that of some species of tanagers and other birds which are non-gregarious in the Quito region and less gregarious here than elsewhere.) The only effect that the presence of this flock seems to have on the PR's is to cause them to "expose" themselves, presumably moving around a little more actively than earlier and
