[[underline]] in lead. [[/underline]] Later on. I saw Black & Blues, PL's, and Yellow bellies in lead.
The Basileuterus and Hemispingus were never in lead. 
[[margin, in red]] Albi [[/margin]]
The [[male symbol]] Albi disappeared after a few minutes. Probably left flock. All the other birds stayed.
Group coherent and moving rapidly. 
The [[underline]] H. atropileus [/underline]] showed preference for bamboo. Ranging 2 - 15 ft up.
All the others went thru all kinds of vegetation. Blue & Blacks 2 - 25 ft up.
PL's and Yellowbellies, 2 - 20 ft up. The Albi, Basileuterus, and wrens ranged 2 - 15 ft up.
Fog and rain come in 10:10 am. and I lose sight of the birds as they go uphill. 
When they left, 1 pair of Blue & Black's seemed to be bringing up the rear guard!
Leaving myself 10:15 am
COMMENTS:
I. As far as my observations here go, mixed flocks seem to be commoner (and much larger) at higher
elevations than at lower elevations. This is very different from the situation on Munchique, or in the
northern part of the Central Cordillera according to my 1962 observations. 
Is there any general correlation between types of environment, or region, and relative development of 
flocks at high and low elevations?
Perhaps the sparsity of mixed flocks at relatively low elevations around Tijeras is due to the fact
that the natural vegetation of the area is heavy forest, and the forest seems to have been cut down only 
very recently, in most areas. There has not been time for much second growth or edge vegetation to 
develop. Perhaps some of the local species have not had time to become adapted to second growth and edge.
