Eastern Cordillera Colombia 

Mixed Diglossini 
September 28, 1962
Páramo de Guasca

[[left margin]] Humer 1 [[/left margin]]
6:45 am. Well above town. Low thick scrub. No trees. See first Diglossa, apparently Ater, just ✓ where we see first tubular red flowers. 

[[left margin]] Laf [[/left margin]]
6:50 am. Somewhat higher up. Similar vegetation, lots of tubular red flowers. Hear lots & lots of Diglossas singing. Apparently all Lafs. Songs all more or less comme ca:

"Zree zree zree zree zree zree zree zree zree zree zree."

Neighboring birds overlapping completely at random; but very frequently. Light is bad so I cannot see singing birds well.

[[left margin]] 4 [[/left margin]] But see several ✓✓✓ Lafs feeding on tubular flowers and/or flitting about in shrubbery. Silent or uttering "Tsit"s

[[left margin]] Laf [[/left margin]]
Birds singing from exposed perches on top of the low trees of which this scrub is composed. Singing postures erect, but apparently unritualized. As far as I can see behavior of these birds does not differ from that of Quito Lafs.

[[left margin]] Ruf 6  Laf 8[[/left margin]]
7:20. Pair of [[rufina?]] ✓✓ ("Rufs") appear in scrub which I know is Laf territory, where Lafs not visible. Feeding on insects on leaves. Utter "Tseet" Notes.  Then one feeds the other. Apparently silent. Then both move on.  Immediately afterwards, a pair of Lafs ✓✓ appear in exactly the same bush where the Ruf feeding had occured, and one or both sing(s) vigorously.  Then both disappear again.

[[left margin]] Ruf [[/left margin]]
A single Ruf ⍻ appears in exactly the same area, collecting
