Breeding Birds of 2017: Cooper’s Hawks

More than 20 kinds of birds have been raising their young in Douglas Park during the spring and summer of 2017.  Here’s a photo report on one species: Cooper’s Hawks.

This year Cooper’s Hawks nested across Sacramento Avenue from the Bird and Butterfly Sanctuary. I was able to follow the progress of the Cooper’s Hawk nest from early March, while the nest was still being built, through July, when both of the young hawks were out of the nest. Later this summer I hope to add more photos of the young hawks as they continue to gain independence from their parents.
