It was a fun evening tonight.  Rosie was off the nest when I arrived and was hunting in the park.  She returned to the nest empty.  Bobby went off to a flagpole, and then disappeared.  He then arrived on the SE corner of Washington Square Arch with a pigeon.

Soon afterwards, Rosie left the nest and took the pigeon from Bobby.  He tended to the nest while Rosie ate.  When Rosie was done, she returned to the nest and Bobby ate the leftovers.

Bobby then went to roost in a tree in the park.
