Mixed Diglossini, Sept 22, 1962, II [[circled]]28[[/circled]]

[[left margin]] Glor [[/left margin]]
without seeing a trace of Glors. I suppose they are rare or absent around here simply because there is too much open grassland about.

[[left margin]] Albi [[/left margin]]
7:53 am Another spot 7500 ft. Can hear Albis singing here. Environment looks rather similar to area where Glors were seen near Téleferico #1

[[left margin]] Albi [[/left margin]]
8:23 am Another spot. 7525 ft. Near Albi singing in dense clump vegetation edge of Glor type habitat. No trees right there but forest not far away.
