Western Robin 34.
May 25
U.C. campus, Alameda Co., Calif.
they stayed fairly near each other,
neither paid any particular attention
to the other.
At 12:35 P.M. I climbed into the Cedrus
Leodana in front of Hilgard Hall to see
how many eggs that Robin's nest contained,
while the ♀ was away. There are 4 bright
blue eggs in it. Just the top, inner
part of the nest contains mud.
The 3 young in the nest in the live oak
tree have now feathered out. They are
so large they seem to hang over the
nest. However, when I approached, the ♀
was sitting on the west edge of the nest,
facing east.
May 27
U.C. campus, Alameda Co., Calif.
The ♀ still hasn't been seen back at
the nest south of Oxford Circle. She flies
into trees near-by, uttering single, clicking
notes in rather rapid succession. The
♂ was still rather close by.
At 4:45 P.M. two of the young in the live
oak tree flew from the nest. They were
about 1/2 the size of the parents. The
backs of the young were dark greyish-brown,
the breasts were reddish-brown on the side
whitish down the mid-ventral line. The
breast feathers were all tipped with black.
I didn't see the young return to the
nest. They flew into the trees near-by.
