On Saturday afternoon, two hawks spent at least an hour circling around Central Park West north of 80th Street. Then one landed on the roof of the Beresford Apartments' SE Tower, while the other landed on the SW Tower. It wasn't clear if it was Octavia and Pale Male or another pair of hawks. They certainly were not in the standard perches.
However, on Sunday afternoon, it was clear Pale Male was in the oval window of the SE Tower, and Octavia was perched just below the oval window of the NE Tower.
Had I just misidentified the hawks on Saturday, or was Pale Male protecting the building after interlopers landed on the building the day before?
