by one bird trespassing into the territory of another, in the course of "escorting" some other species. 

[[left margin in red]] Albi [[/left margin]]

Like the dispute among the [[male  symbol]] Albis at La Palma in the Western Cordillera.

I suppose that the disputes among Albis when other species pass

by may add to the attractiveness of mixed flocks.  Like the disputes among Yellow-thighed Finches in Chiriqui.

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

I hear a few more presumed Cy Songs (NODWA) from time to time during this period, [[underlined]] but not when either [[female symbol]] or [[male symbol]] Albis are visible [[/underlined]] !

When the [[female symbol]] Albi and "Yellowfaces" were close together in bush

earlier, the group was visited by a single hummingbird.  Apparently [[circled in green]] 10 [[/circled]] [[circled in pencil]] 9 [[/circled]] [[1 green checkmark]] Whitethroat The hummingbird did not attack, and soon flew on.

Some minutes after the [[male symbol]] Albis have come and gone, a single [[green checkmark]][[underlined]] H. atropileus [[/underlined]] [[circled in pencil]] 10 [[/circled]] [[circled in green]] 11 [[/circled]] appears in bamboo similar region.  6 - 12 ft up.  Silent. Apparently at least 100 ft from nearest bird of another species at the time.

Also disappears almost immediately.  A few seconds later, I see a [[circled in pencil]] 11 [[/circled]] green checkmark]] small wren (species unidentified) same region.

All this occurs ca. 7:20 - 7:45 am.

I think that all these birds, from the presumed [[underlined]] Ensifera [[/underlined]] to the [[underlined]] atropileus [[/underlined]] and the wren [[underlined]] may have been members of a single, real, social group. [[/underlined]] But, if so, the group as a whole was [[underlined]] very diffuse. [[/underlined]] (Rather Sierra-de-Merida-like!) [[underlined]] Apparently without real leaders. [[/underlined]]

Fog starts to come in, ca. 8:10 am.

During period 7:55 - 8:20, I can hear occasional snatches "Yellowface" Song and [[underlined]] Basileuterus [[/underlined]] and/or [[underlined]] Hemispingus [[/underlined]] -type sounds in the neighborhood.  These birds [[underlined]] apparently [[/underlined]] are not close together now. And the other species are neither audible nor visible.

Then, 8:25, I hear more sounds which suggest that other birds
