Mixed Diglossini, Apr. 30, 1965, II.

[[margin]] Scan [[/margin]]  Presumed Scans in Abu 5:47 a.m.

Andean Sparrows and House Wrens singing quite strongly and steadily.  They, at least, are presumably in breeding condition.

Everything very dull 6:00 a.m.

The Abu flowers [[underlined]] don't [[/underlined]] seem to have Diglossa holes in them!

I am beginning to think that [[underlined]] very [[/underlined]] humid environments around the 7000-8000 ft level are unsuitable for Diglossas!

[[margin]] Scan [[/margin]] 6:12 a.m.  The Scans are not visiting the Abu here (which is red) nearly as frequently as they did some of the Abus on the University grounds in Bogotá.  Is this because the Abu here is not at the right stage???  It certainly has [[underlined]] plenty [[/underlined]] of flowers on it!

6:21.  See a green hummingbird, which [[underlined]] may [[/underlined]] be a [[underlined]] juvenile [[/underlined]] Scan, feeding on Chorrillos.  Sticking bill up tubes.  I don't think I ever saw a Scan feeding on Chorrillos in Bogotá.

[[margin]] Scan  Gen [[/margin]]  This may be one of the very few places where Scans occur [[underlined]] without [[/underlined]] Diglossas (especially [[underlined]] carbonaria s.l. [[/underlined]]).

6:31.  See single Sooty Thrush alone in patch of wood along stream adjacent to garden.

Leaving this garden 6:41 a.m.

Then go on up hill.

[[margin]] Blue [[/margin]]  (As the notes on mixed flocks indicate, there is at least 1 Blue Diglossa not far from the Finca.  Interesting that it apparently does not come into the garden.)

[[margin]] Scan [[/margin]]  On my way up hill, I didn't see any more Scans.  This species does seem to be primarily an inhabitant of gardens and a
