St. John the Divine has two fledglings.  One most likely went off the nest late Sunday and one on Monday morning.  When I was there one was on the southern side of the Cathedral and the other on a fence just north of One Morningside Drive near the guard station.  Both looked great, although the one on the Cathedral looked a lot more confident than its sibling.  The fledglings are in very safe locations away on the Cathedral campus, which is a quiet enclave.
