124 THE CONDOR Vol. XXIII 
One bird presently moved across to the bay tree at M, and was followed shortly 
afterwards by two more. Three others retraced to H, and the main body of the flock 
stragegled after. The birds at M, finding themselves left behind, hastened after their 
companions. All now returned to the thicket at N, foraged slowly over to O, then down 
to P, and finally crossed the road to Q in their characteristic straggling fashion, one 
bird venturing out and being followed shortly by the others. 
In counting the birds as they flew across the road at this point, I was surprised 
to find that the flock now numbered 21; 5 stragglers, either of this or some other 
flock, had been gathered up in the thicket. - 
The flight from P to Q occurred at 10:45, the flock having remained for almost 
an hour in a patch of brush about one-eighth acre in extent. 
The birds foraged in the one large oak at Q for 24 minutes. 
At 11:00 o’clock 
cone bird ventured to another oak at R, but none of its companions followed, and it soon 
returned. At 11:09 a bird flew across to S, but seemed timorous and at once returned

to Q. Then another ventured across, and the flock presently followed in their usual 
manner. At T a Sparrow Hawk appeared and perched on a near-by post, but was not 
noticed by the Bush-tits. 
At U the flock became divided, about half remaining at V, the rest foraging in & 
fallen oak (still green) at W. Later the two divisions rejoined, with the exception of 4 
individuals (2 pairs?) which remained behind and did not rejoin the flock as long as 
I observed them. I interpreted this as an indication of the advent of the mating season, 
when the flocks gradually break up into pairs. Subsequent observations showed the 
flocks to be rapidiy dwindling, and tended to confirm this opinion.
