Pre-School for Cooper's Hawks

The Cooper’s hawks have had a huge family this year. They first mated back in March. They must have lost the first clutch, but they are making up for it. There are four recently fledged juveniles hanging out in the backyard. In the morning and late afternoon they raucously call for their parents to bring them food.

Two of the larger juveniles are starting to follow the parents. It would be fascinating to see if they are watching their parents hunt.

Catching enough food to provision the four youngsters, who are now as large as their parents, is a Herculean task. The parents aren’t being picky about prey; rats have even become part of the fare.

With four youngsters to watch over, it's understandable that while the parents were off with the bigger chicks when they first left the nest, they missed that the little one didn't want to be left behind. The little hawk was not yet able to fly and ended up on a neighbor's front porch, just steps from the sidewalk. The flurry of humans wanted to "save" the little guy. But these hawks are devoted parents, like most birds, I convinced everyone to give the parents time to collect their youngster. I relocated the juvenile a short distance from its landing spot to an area that was away from the sidewalk, shaded yet visible to the parents. The parents did return and communicated to their little one what it needed to do, to get safely up into a tree.

He is flying a little, but still not well enough to follow the parents. The smallest of the juveniles he's pictured here. He's hungry enough that he has started trying to catch his own food. His movements are not skillful and his attempts seem to be in slow motion. He went toward a group of house finches, who stayed just out of his reach, then he turned to go after a fox squirrel. The squirrel couldn’t believe its eyes at first. It moved just out of the young hawks reach, then actually came back to taunt the young bird.

When he isn’t calling for his parents, the young hawk sits watching the small birds that one day will be its food staple. He’s learning how they fly, their alarm calls, how they respond to threats. His sharp eyes are ever watchful.  Cooper's hawk on fountain.

Meanwhile the California towhees are taking no chances. They are teaching their youngster to fly under the covered patio and carport. No use tempting the young Cooper’s hawk to make its first self-caught meal a young towhee just learning to fly.

A Pair of Cooper's Hawks

It is official, the Cooper's hawks are trying to start a family. 


For three hours on Sunday, an immature Cooper's hawk sat on the power line above our bird feeders in the rain. The bird did not seek shelter and looked a bit soggy with a drop of water dripping every few minutes from its beak.


Last year a pair of Cooper's hawks successfully nested in a large jacaranda tree about a block away. This year an immature individual began hanging around about a month ago and was occasionally seen with a mature bird. The immature Cooper's hawk pictured here does not yet have the distinctive gray cap and back of an adult. It is still more brown in coloration around the head and shoulders. Notice the banded tail typical of Cooper's and sharp-shinned hawks. These fast maneuvering hawks are bird predators and their appearance in the yard has disgruntled the band-tailed pigeons.

I wasn't quite sure of the relationship between the two Cooper's hawks, but yesterday it all became clear.


The immature or young hawk is a female and the adult is a male. He brought her a mourning dove yesterday to seal their relationship and prove his ability as a provider. She accepted the dove and his sexual advances. Occasionally, I see one or the other of them fly past the window with a stick or pine bough. They are building a nest, but I haven't spotted the location yet.


If you are noticing nesting birds in your area, take a minute and consider documenting the nesting attempt on Cornell University's NestWatch website. Scientists can't be in everyone's backyard, but you can play an important roll for scientists; be their eyes, ears and observers. 


The Bewick's wrens were back working on their nest in the lariat house yesterday. And I'm still searching for a hummingbird nest; there have been starts and stops due to the rainy weather. Follow the daily progress of your nesting birds. You'll be surprised by their daily dramas and joys. Document it all with just a few minutes every 4 days and you'll play an important roll for science.
