Western Robin
5.
May 14
U.C. campus, Alameda Co., Calif.
on the nest, Still no sign of the
other parent.
at 6:20 P.M. I located another Robin's
nest that apparently has just been completed.
[illegible]
it is about 12'
above the ground on the east side of a
Deodora tree just south of Hilgard Hall.
May 15
at 1:50 P.M. an adult was seen to fly to
the top of LSB with some food in its bill.
it uttered low, clicking notes-3 or 4 at a
time - at irregular intervals varying from
1 second to 10 seconds. Each time it uttered
one of these notes, it bobbed its tail in a
very pronounced manner. at 2:01 P.M. it flew
to a near by tree and was lost from sight.
May 16
at 9:00 A.M. when I arrived at the nest in the
Deodora tree, I found one of the adults standing
at the edge of the nest. It remained motionless
for several minutes. at 9:16 A.M., the other
parent, which was the ♀, chased the ♂ from
the nest & proceeded to sit upon it, facing N.W.
The ♂ flew to the ground about 30' from the tree
& began the job of catching worms.
The nest is constructed entirely of dried
glass stems, at least on the outside. As
yet, I haven't been able to determine how the
nest is lined.
At 9:37 A.M. a luck-tit began foraging in
the branches within 10' of the nest without
seeming to disturb the bird on the nest.
