Aphelocoma coerulescens
March 5 Queens Rd, Berkeley
Gathering
Pair observed nest material.
The male of the pair came into a
thicket hedge and worked thru it
systematically, pulling fairly thick
twigs (1/8-1/4 inch in diameter) and
attempting to bend them. The male
did not succeed in breaking any
twig but continued his efforts for
fully five minutes. He then
flew to a high vantage point as the
female came out from a spot on
the same slope carrying a large
twig in her bill. He uttered a soft
conversational chick note intermit-
tently while examining twigs. The
female was probably 200 feet away,
and not within hearing of him at the
time. The male, in searching for twigs,
confined himself to the shrub
shrubs, progressing even into dense
twiggery where he worked his way
through with slight awkwardness.
He did not examine or call loose
twigs on the ground around the
hedges.
