seen singing this morning were conspicuously visible, but not spread.)

^[[Albi]] The Albis here seem to be completely non-gregarious, like the birds near Bogotá.

October 31, 1962
Boqueron de Tollo

Arrive usual place 5:30 am.
^[[Bari]] Baris beginning to sing.

One bird singing "Zee zee zee zee z[[underlined]]eee[[/underlined]] wa".
No Albi or Grassquit song yet. Baris usually alternating pretty well. Only occasional overlaps.

^[[Bari Albi?]] First Albi or Grassquit song heard 5:33. Overlaps with Bari. Then some Bari songs overlapping one another. then more Grassquit or Albi songs. Overlapping quite frequently at first. Then tending to alternate with Bari songs. Then overlapping Bari songs again. Then alternating again. (I think all the R's being uttered now are by a single Grassquit. Certainly in an area which was Grassquit territory yesterday.) No overlap R's different birds (if more than one bird is uttering R's now).

^[[Bari]] Bari songs already decreasing in frequency 5:38.

Now there are certainly several birds uttering R's. Occasional overlaps (but not too frequently). Baris quite stopped.

^[[Bari]] Original overlaps Bari songs & R's usually occurred when bird uttered R after Baris had begun to sing. So perhaps Grassquits don't react to Bari songs very strongly after all.

^[[Bari]] 5:40 Now only occasional Bari songs and R's. [[underlined]] Not [[/underlined]] overlapping
