bellies I have seen here - yet.)

[[margin, in red]] WCC [[/margin]] Why were there no WCC's with this flock? Is this altitude too high for them?

[[underline]] Very [[/underline]] light rain started and then stopped again during this second period of observation of the flock.

Flock eventually goes down hill out of sight. Whole area quite quiet now, 9:55 (except for some thrush sounds down hill)

[[margin, in red]] 26 [[/margin]] 10:07. Going down hill. Come across [[red checkmark]] Whitebeard apparently alone in tree. Very noisy. 20 ft up.

Then see single wren in tree 20 ft away. Uttering lots of thin, high formless twitters. This [[underline]] certainly [[/underline]] is the species which has been uttering the peculiar twitters of this type around here which have been puzzling me (because I was afraid they were diglossine and I couldn't identify them).

SEE ALSO TODAY'S NOTES ON MIXED DIGLOSSINI
COMMENT: This morning's observations would seem to confirm, more or less, what was seen on previous days. Mixed flocks here seem to be generally comparable to those in the Eastern Cordillera. (But) they are most highly developed in slightly or moderately bad weather. The important nuclear species are [[underline]] Buthraupis eximia [[/underline]] and [[underline]] Pseudospingus [[/underline]].
[[margin, in red]] Sitti [[/margin]] Possibly also White-bearded Flycatchers (they seem to join mixed flocks more frequently, and are more obviously active nuclear, here than in some other parts of the Andes). The Sittis also are extremely important (passive nuclear or passive-cum-active nuclear) whenever they are [[margin, in red]] Gen [[/margin]] present. The two [[underline]] Poecilothraupis [[/underline]] species, the other Diglossini, and the Yellow-faced Whitestart seem to be less important. (Perhaps some of these species are less important in mixed flocks here than in some
