6x12  Oil on Brown Walnut
 
This species was named in 1828 by Charles Lucien Bonaparte in honor of his friend and fellow ornithologist William Cooper.  The Cooper's hawk has lovely reddish bars across his chest and flies with a flap-flap glide pattern.  An attack maneuver is to fly fast and low to the ground, then up and over an obstruction to surprise his prey on the other side.  He lives in the US but if her lives in the west he is substantially smaller and weighs around 1/5 less than if he  lives in the east.
