(9 July) Upon my arrival here today, a ♂ (?) Cooper's
hawk was rumaging near a Brewer's blackbird
nest, presumably looking for goodies. He hopped
around in the vegetation, with the ♂ Brewer's
scolding from a distance. Getting impatient, I
flushed him and out he flew with a chick
(I presume it was a Bbb chick). Anyway I
start my watch. After an hour and only
one baby ID, I quit. As I begin to walk
away (got about 10 Feet), I hear an ACW
scream, a baby, From the valley oak uphill
by the Fence From the barn (where I had
been watching - having heard a baby in there)
A Cooper's hawk! The adult ACW's
karrilled where they were (nest tree, givanny)
but did not go in to mob the COHA. So
I did. He flushed with the baby still
screaming intermittently. It must have been
a burden (i.e. a ♂ COHA) because he
descended to the ground while Flapping.
My chasing didn't make him drop the baby
(though I never got very close) I should've
yelled loudly but I forgot to (in shock)
He finally disappeared with the baby clown
toward the pump, flying low and labored the
whole time. I later learned that Danny
found the GYG baby( ) (no paint?) on the
