Mixed Diglossini, Oct. 23, 1962, III

but neither of the latter were visible or audible at same time. 

[[left margin]] Laf [[/left margin]]
There seem to be several Lafs around here singing from time to time. 6:40 am

There are also a lot of migrant warblers around here. 

[[left margin]] Humer [[/left margin]]
6:45. Hear several bursts of what sounds like "Humer" song yesterday. Brief, like songs heard yesterday, but with little or no R component (a "seeeee" in place of R – possibly a low intensity "int. mov." of R). Can see these are uttered by black Diglossas, but can't see the birds well enough to make absolutely sure of their specific identification marks. 

[[left margin]] Ruf [[/left margin]]
Rufs seem to have disappeared from area now. Probably comparatively mobile here too. 

[[left margin]] Ruf? [[/left margin]]
The long R's heard earlier may have been uttered by hummingbirds, not Rufs. 

6:50 Can hear more Laf songs uphill

[[left margin]] Cy [[/left margin]]
7:05 Now I think I can hear a Cy singing in this area a little distance downhill. 

[[left margin]] Laf Cy [[/left margin]]
Burst of "Laf" song seems to stimulate presumed Cy to sing. Overlap. Then "Laf" stops, "Cy" continues. 

[[left margin]] Humer [[/left margin]]
7:15 Definitely see a Humer in this area. Silent. Alone (?) 

All the Humers here seem to be remarkably silent, skulking, nervous, & active. 

[[left margin]] Laf [[/left margin]]
"Lafs" still singing quite frequently 7:17

[[left margin]] Humer [[/left margin]]
Again see definitely identified Humer feeding low in scrub. Apparently feeding on insects. 

[[left margin]]  Laf Humer [[/left margin]]
Have several times heard "Lafs" sing when I thought there were Humers in area. But have not seen such incidents clear
