Lizard hawk I at shot. One
bird flew as we approached.
There were several of the
large yet most prudent.
In this dense association
I judge true there seem to
be several different things.
This is the best workable
place of this association we
have yet been able to find.
During the past few days
after examining many trees
sheets I have come to the
conclusion that the nests are
used as roosts throughout the
year.
Although some rurus may
have eggs most are only
roosting when we flush
them for the nest.
Today after leaving the
hawk vicinity we worked
up the hill into some good
juniper timber. Several
woodpeckers were about the
large trees.
There was here a flock of
sprayed Cowbirds (mules), adult
female and young packies..
At one time I heard a
female Cowbird give a
chalin call (like 'Oryall' bylwd).
and saw the flock of
males swum in that direction
