I arrived to a quiet afternoon in Astoria. One of the parents was on the bridge and the eyas still on the nest was making practice jumps around the nest and up to a bracket on the bridge.
At some point the fledgling had enough and flew south to a residential block of Astoria. I walked around the block looking for it, but couldn't find it. I think it was on a flat roof that wasn't visible from the street. With the excitement over, I returned to Manhattan.
