Cooper's Hawks are a bird eating raptor, eating birds like pigeons, robins, and sparrows. Adults have blue-gray backs and heads, with a white belly with orangy markings along their breast. They also have long thin bright yellow legs. COHA are cool because they exhibit a high degree of reverse sexual dimorphism. This means that female Cooper's Hawks are usually much larger than the males.
My project with COHA is simple. I trap the adults and band them with special colour bands so that I can identify individuals again without having to recapture the bird. I trap them at their nest so we can learn how if adults come back to the same spot to raise their young and for how long.
We also band the young birds in the nest and observe the nestlings after they fledge (leave the nest). Again we can identify birds as individuals because of the red band so we can tell which chicks stick around the nest after they can fly and for how long.
