ay's observations do not necessarily conflict with my earlier conclusion that species are more segregated here than in many other regions

NOTE: It must be significant that PL Atlapetes (and the presumed [[underlined]] H. frontalis) definitely [[/underlined]] were not associated with the flocks seen this morning. Possibly also significant that [[underlined]] Margarorius [[/underlined]] apparently was not associated. (I might add, in this connection, that [[underlined]] all [[/underlined]] other dendrocolaptids appeared to be rare or absent here.) Thus, some species appear to be non-gregarious here - in spite of the facts that there are flocks here, and that the same species are gregarious elsewhere!!!!!!

NOTE: One point might be stressed. Altho, in the Central Andes, mixed flocks may be confined to frontiers with the Upper Sub-Tropical Zone, they [[underlined]] certainly [[/underlined]] occur along other types of frontiers in Venezuela, Colombia, and Bolivia!

Carpish Pass.

Going to work slightly different area this morning. Just past rest of pass, on eastern slope. Arrive 5:30 am. Still quite dark. NOTE: This area must be slightly lower than the area worked yesterday; but it registers as 9000 ft on my altimeter now!

Walk down road to 8925 ft, approximately. There seems to be more bamboo and other second growth here than in the area wo
