"Cooper's Hawk, backyard resident pair, 2013"
Between late March and early August, 2013, we had a Cooper's Hawk pair hanging out in the backyard ... a larger immature-plumaged (presumabley female) and a smaller adult-plumaged (presumabley male) ... while we have seen them together, they seem to take turns hanging out separately, and are often visible through our picture window ... the "local crows" harass them and they in turn chase the Crows ... in the middle of July two juveniles showed up and they were thoroughly enjoyable !!!!!! ... the youngsters were noisy, clumsy, and totally entertaining ... we got to watch them learn to balance on the limbs of our Chinese Empress tree, learn to fly from branch to branch, and learn that one can NOT catch a "tweety" by chasing them up and down the limbs ...

... April 10, 13, and 16... "mom" ...

NOTES: ... in late March an immature-plumaged Cooper's Hawk began hanging around the backyard ... we could hear calling too ... in mid-to-late April a smaller adult-plumaged Cooper's was seen ... when the two were seen flying together it was noticeable that the adult-plumaged hawk was smaller than the immature-plumaged hawk ... we therefore assumed the immature-plumage was female and the adult-plumage was male ... according to Cornell's "Birds of North America" online edition, immature female Cooper's Hawks would often breed ...

... July 2 ... "mom" ...

NOTES: ... in early July we heard "mom" making a different cry as she flew from tree to tree ... it was harsh in sound ...

NOTES: ... on July 14th the hungry screams of fledglings could be heard in the distance and "mom" was in the yard ...

NOTES: ... on July 18th the two siblings were first spotted in the yard ... what fun !!!!!!!!

NOTES: ... sometime shortly after the 18th "mom" was seen flying directly towards, and then passing, a flock of crows making a fuss on the neighbor's roof ... she led the group south, away from the backyard ... on July 29 she was seen pecking at the tail-end of a Crow chasing it from the yard ... (go mom !!!!) ...

... July 18 ... "the kids" ...

NOTES: ... the youngsters were noisy, clumsy, and totally entertaining ... we got to watch them learn to balance on the limbs of our Chinese Empress tree, learn to fly from branch to branch, and learn that one can NOT catch a "tweety" by chasing them up and down the limbs ...

NOTES: ... the first sign of "hunting" we saw was on July 28, when one of the youngsters would circle a tree in which there was a squirrel ... simultaneously the youngster was emitting alarm calls as he flew from tree to tree ... this behavior was very similar to what we'd seen the adults do ...

... August 11 ... "dad" ...

NOTES: ... "dad" was spotted once, on August 11, and about the same time "mom" and "the kids" moved on ... it's very quiet in the yard now ...

NOTES: ... American Robins have moved back into the yard (late August) ... and on the 23rd we noticed a Northern Flicker back in the yard ... both of these birds had disappeared during the reign of the Cooper's ... the Robins were eaten (we would find feathers) but I'm thinking the Flickers just stayed away ...
