I walked N after 10:00 searching elm - Tanoak grove where I took pair (538-539) last April. No birds heard in this area so I worked up side draw to W where juniper had been cut. Song heard once well upslope but titmice generally silent. WIND INCREASED AFTER 10:00. AT 10:45 I walked upslope to the "mesa" top where I heard titmice singing. There was an exchange of song in juniper and liveoak N of a grassy double-fenced pasture, I located one pair of titmice in a liveoak at 10:50 and watched their foraging activities (3?, 2 minutes, & 4 min.) :
twig 11
fruit 1
branch HHH- HHH-HHH
leaf 1
{both birds appeared to be equally dark-crowned when seen through binoculars}
The &? flew to liveoak W at 10:52 and sang peter--- (6 phrases per song bout). I gave note twist-et or twitch-vet as he sang. Both gave location notes tset. I lost track of birds as they flew W at 10:54 but saw one bird peck at object on mesquite trunk (in direction they had gone) at 10:58. This bird flew to liveoak S of fence. &? there sang tyur---- 12 phrases per song group. The &? to the N answered but ceased singing first. I followed that pair. The birds were foraging in a juniper, although their activities were concealed for the most part. They spent a full minute in the juniper, then flew N
