Mar. 1
Strawberry Canyon, U.C. campus — Alameda Co., Calif.
2 birds resting on edge of stadium (north end).
One flew to a black locust, where, after a few
seconds of exchanging tips, the other also flew
to the same tree. Time: 8:15 A.M.
At 8:35 A.M. 3 juncos were seen feeding in short
grass in an old road-way in company with
several Brown Towhees. The juncos tolerated others
of the same species to feed very close, nor did
they pay any attention to the Towhees when
they approached very near. More of the flock
appeared, as did a Calif. Jay. Occasionally,
something would startle them so that they would
immediately retreat within the shelter of bushes
close by (about 50' away). One began to feed on
grass about 10' away, but was soon startled away. The
birds usually move as a flock, the formation is
rather loose, however. Although there is an integrat-
ation of color, the ♂ tends to have a darker head
than the ♀.

At 10:20 A.M. one bird was seen about 2' above the
ground on a small bush. We approached to within
about 10' of it before it decided to move.
