On Christmas Eve, we had a mystery.

Around 4:00, Pale Male and Lola are on the Beresford's southeast tower.

At 4:10, I found this adult Red-tail on a building at 86th and Central Park West.

The bird moves south a few buildings.

Landing on a building at 83rd or 84th.

After a brief stop the hawk flies north, making a number of cries.

I lose sight of the bird, but it looked to be going into the park around 86th.  So, I walked north of the transverse, and two dog walkers pointed to this bird perching in this tree just inside the north 86th Street entrance to the park.

I thought it was Lola, but she slept on the Beresford according to Lincoln Karim.  So, who is this mystery bird? Is it the same hawk I had on the rooftops?  Or the bird that elicited the cries from the rooftop Red-tail?

The Red-tail was in the tree way after dark.  This was a 3 second exposure taken at 5:15 p.m.
