Hawk-watching friends who were in Washington Square Park during the day today reported seeing both Bobby and Rosie perching, flying, and eating vermin. They ate mice and a rat. At one point Bobby caught a mouse and gave it to Rosie to eat (not long after she had eaten a rat).
There was also what looked like a Sharp-shinned Hawk hanging out in the park today. Rosie tolerated it for a while and then eventually drove it out of the park.
Bobby and Rosie were at the roost just as I got to the park. Bobby above, Rosie below:
