[[circled]] 53 [[/circled]] Leaving 10:20 am. COMMENT: This morning's observations would seem to confirm my impression that Allogregarious behavior is very stable in this area. (And again, I heard lots of birds - mostly uttering "CN"s - which I was not able to see.) August 24, 1965 Paramo de Guasca Going to work usual place here. Arrive 5:27 am. Still dark. Semi-fog and/or light drizzle. No wind. Relatively warm. Thrushes already Singing when we arrive. A lot of them and quite loud. Everything else silent. A few other bird sounds (miscellaneous) begin 5:35. Then everything rather quiet 5:40. Incidentally, the altitude, where the car is parked, is 9800 ft according to my altimeter now. Then more bird noises. Now working where Laf, Coer, and PL Atlapetes were heard overlapping a couple of days ago. Atlapetes utters Whistle Songs 5:45. NODWA. Then shuts up.
