Mixed Diglossini, Oct. 22, 1962, III            15 

[[left margin]] Laf Humer [[/left margin]] 
restricted to the taller and denser vegetation (which would, of course, provide them with the best vegetation in severe weather). "Humer"s certainly not congregated in sunnier areas. 

[[left margin]] Humer [[/left margin]] 
It is barely possible that there is only a single "Humer" here, which I have been hearing at different borders of its territory. 

[[left margin]] Humer [[/left margin]] 
The "Humer"(s) heard today was (were) nearer 9800 ft than 9700. 

[[left margin]] Humer [[/left margin]] 
The area below Guasca where Humers were seen last month is at an altitude of approximately 8600 ft. 

Area where large mixed flock seen above Guasca is approximately 9500 ft. 

4:15 pm In hills above Bogotá 

[[left margin]] Ruf [[/left margin]] 
4:25 See what is almost certainly single Ruf. Silent. Flitting about in gorse-like bushes 8900 ft.

[[left margin]] Cy [[/left margin]] 
Then get a brief glimpse of a Cy further on in tree. Again a single bird. Apparently feeding on insects.
 
Lots of N. American warblers around here. But neither of the diglossines seen so far has been associated with them. (Incidentally, in case my notes aren't clear, the Ruf & Cy cited above were not associated with one another.)

[[left margin]] Humer [[/left margin]]
4:55 pm. A little further up hill. 9025 ft. See single Humer in Eucalypt tree. Not feeding. Flies away with "Seet" Notes. 

[[left margin]] Cy [[/left margin]]
Some distance farther on, find a pair of Cys, hopping in low scrub.

[[left margin]] Cy Humer Ruf [[/left margin]] 
Walking around same general area for another 1/2 hour. See another Cy, another pair Rufs, and the same Humer again. All
