Bald Eagle and Osprey.they never fly together, most likely the male Osprey is defending his nest from the eagle. Last season, one of the Osprey nests I watch lost both chicks to a Bald Eagle. Not a happy outcome, but it's nature 'doing it's thing.
This is my best Osprey shot in my first year of bird photography. It took several weeks to learn the ospreys behavior and 7 mornings of waiting to catch this one in the right light. It finished in the top 100 in the 2012 Audubon Magazine contest.
Cooper's Hawks capture birds with their feet and kill them by repeated squeezing. They have even been known to drown their prey. Three Cooper's Hawks were found in Central Park in this year's Bird Count.(I had a Cooper's Hawk on my NYC terrace February
