There were no hawks on the nest this evening, and reports are that none were seen today by anyone. So, we assume the single eyass has fledged. The parents were spending a lot of time above the Pless building, so the fledgling is most likely on its roof. A group of us are eager to see how it's coping with the few primary and secondary feathers that are missing. It would be nice to see a few normal flights.
Update: 6/15/16 The fledgling has been perched and flying well in the SW corner of the park today. Reports are nice flights, to perches high on buildings. So, the wings might not look perfect but they certainly work just fine.
