Mixed Diglossini, May 23, 1965, II  (62)

surprised if the Whitestarts here are breeding now.

Rain getting lighter 6:03

Whitestarts Sing some more. Then shut up. Their Songs do overlap at least some Atlapetes Whistle Song-type vocalizations not far away. Also some wren Songs. But there are so many birds vocalizing around here that the Whitestarts could hardly "help" overlapping.

^[[Cy]] 7:19. Hear what sound like Cy Songs in distance. No other Diglossine or Whitestart audible at the time (Whitestarts have been "niched" out of the area with enormous mixed flock.) Cy Sings only a few phrases. Then shuts up.

^[[Albi 22 Cy]]  7:55. See small ^[[checkmark]] black Diglossa fly across road. Near where [[male symbol]] Albi was seen yesterday. This also is not far from where second large mixed flock seen a few minutes earlier. This flock included Cy. It is interesting that Albi did not join. Are Albis less likely to join flocks than Cys or Lafs here?

Going to work same place as yesterday.  Arrive 5:25am. Heavy fog! Cold! And still very dark

6:10 Hear high thin Twitters in distance. Sort of "Tah-tah-tah-see-eeeee-ee-ee-yoo". Possibly diglossine? (This is area where Cy seen yesterday) Or possibly wren???  Only a few phrases. No (other) diglossine, Whitestart, or Atlapetes audible at the time.

Then hear first Whitestart Songs 6:12. No overlap. Again only a couple of phrases.
