Mixed Diglossini, Apr. 21, 1965, VII  80

MISCELLANEOUS COMMENTS:

[[left margin]] Bari [[/left margin]] 
As noted above, there are no Blue Diglossas here. Have I ever seen Blue Diglossas and baritula s.l. in the same areas. Do baritula s.l. and the Blue Diglossas compete with one another particularly strongly?

[[left margin]] Blue Conirostrum [[/left margin]]
It also is surprising that there are no conebill-types here. Why??? In particular, why is CC absent??? Can it be excluded by the presence of baritula s.l.???

[[left margin]] Humer [[/left margin]]
The more I think about it, the more impressed I am by the behavioral peculiarities of Humers. It seems to be at least as distinct, within the carbonaria s.l. "superspecies", as Carbo itself. Something tells me that I will have to look at the areas where its arrange approaches, and/or overlaps, there of Glor and Ater!

Going to work on Guadelupe this afternoon. Arrive region Prime Eucalypts 3:15 pm. Just as rain stops. 

[[left margin]] Humer 107 [[/left margin]]
There aren't many birds in Primes. 2 or 3 Humers ✓✓. 2 or 3 hummingbirds (several species). Quiet. 

[[left margin]] Laf [[/left margin]]
Nothing in area where presumed Laf seems to be holding territory 3:20-3:30.

Go uphill, and then down along path thru very thick vegetation (where Lafs were common in 1962). Nothing 4:07 pm Rain has stopped

Not even a sound of a bird!

4:17. See some single sooty thrushes in distance. Also an occasional hummingbird (no Scans).

Then hear Firebelly songs in distance.

[[left margin]] 108 [[/left margin]]
4:31 pm. Catch brief glimpse of Black Diglossa ✓ low in very dense scrub. Silent. Apparently alone.
