Bobby and Pip were seen around Washington Square Park August 1st (a day I was not at the park) but they were not to be found when I and a couple of other hawk-watchers searched the park and the area on the 2nd. We were there for about two hours but no luck. No hawks were seen during a brief walk around Union Square Park as well. Not to worry, they could have been anywhere around that swath of Manhattan.
In the meantime, here's a screen shot flashback of little Pip relaxing after a rain shower. Image is of a screen shot I took on June 7th, 2011 (a couple of weeks before she fledged).
