2 notes rather like the CN's of the Palm & Blue Notes. Notes like the latter also occurred from time to time in the midst of the set of three song phrase. Much of this singing was done from quite unritualized sitting, standing, or hopping postures; but one, for about a period of 5 minutes, the bird sang repeatedly from the very fluffed posture drawn on the preceding page. I am not sure if this posture is really ritualized or not. It might conceivably be nothing more than a resting posture. The bird had also been preening from time to time before singing, so the posture might also have been an indication of "comfort activities" motivation.

During the songs, this bird looked around from side to side, and/or peered up and down, obviously "looking" for something - presumably a mate.

One thing I did notice about this bird, and all the other Bay-heads I have seen, was that it sang when well inside a tree (probably about 12 ft up), not on an exposed perch at the top.  In other words, the bird was not advertising itself as conspicuously as singing birds of many other species.  This might, conceivably, be the first indication of the partial obsolescence of song.

Both the Bay-heads and Silver-throats I saw today were behaving much as they did when I saw them here before, last year; insofar as they were not really gregarious, but I did see birds of both species in association with the "feeding associations" (see today's General notes) - something which I had not seen before.

One pair of Bay-heads in a "feeding association" were accompanied by two fully grown young.  I didn't see any Silver-throats today which appeared to be juveniles.

The two young Bay-heads with their parents did a lot of begg
