The fledglings' first day in the park seem to have been a great day for them. Folks found both fledglings, and both parents were easy to find during the day.
I arrived in the evening to find two adults and a fledgling. That fledgling took off from the Silver building, first for a tree and then ended up trying to land up on 2 Fifth Avenue. It miscalculated its landing on 2 Fifth and ended up in a fenced in garden that is now a construction site.
Bobby took some left over food from Silver and eat it on the building directly to the south. The other eyass who had been on that building (where Pip hung out after fledging), ended up on a window on Silver. Rosie was on a flag pole for much of this time so we had three hawks, two adults and the other fledgling, in view.
