On Saturday, I explored the park looking for raptors.  My first was a Merlin falcon on a water tank on top of the Lincoln Correctional Facility on 110th Street.   It was chased away by a mob of Crows.  Later, I saw a Sharp-shinned Hawk hunting, although it was too fast to photograph.  As I ended my walk, I saw the female Red-tailed Hawk, Lima on a 5th Avenue building around 77th Street.
