Mixed Diglossini, Oct. 30, 1962, III.  (3)

Going uphill 7:05 am.

^[[Albi]] Just as I start, finally see a [[male symbol]] Albi singing  Perched in bush, on exposed branch, about 3 ft. above ground. In unritualized more or less diagonal posture. Tail does [[underlined]] not [[/underlined]] rise during songs. Songs perfectly good R's. No special preliminary or terminal notes

^[[Albi]] I think I may be sorting out R's now. Grassquits utter both low-pitched and high-pitched R's (or Trll's). High pitched are sometimes (not always) slower than low-pitched. R's of Albis are most like low-pitched Grassquit R's; but probably not so "hard", possibly even faster, and perhaps a little softer. But I still wouldn't care to identify them by sound alone.

^[[Bari]] ^[[Albi]] There were several particularly interesting aspects of this morning's Albi-Bari-Grassquit performance. The fact that there were no overlaps between Bari songs and R's of other species means that the Grassquits were also refraining from singing while the Baris sang. There were also few or no overlaps between R's. I don't think Albi R's overlap very frequently. But the Grassquits must also have been refraining from singing while the Albis sang! And of course both Baris and Albis refrained from singing while the Grassquits sang  All in all, the Grassquits here would appear to be [[underlined]] integral [[/underlined]] members of the "diglossine singing society"!!!

^[[Albi]] The Albi seen singing today was in almost exactly the same spot as the Albi glimpsed yesterday.

Fog coming in 7:25 am.

^[[Albi]] 8:20. See single [[female symbol]] or juv Albi (definitely identified) fly out of scrub into low wet forest  7175 ft

9:30 am. Hear what [[underlined]] sounds [[/underlined]] like Albi in uncovered thickets
