A pair of Bald Eagles have fledged two young in a communications tower of some sort behind an industrial building across the street from the preserve.
The nest site, if I recall correctly, was formerly occupied by Ospreys.
Today when I was checking it out, an Osprey flew by, touching off vocalization by an adult perched near the nest.
I was told by someone who works nearby that this is not one of the nests that is monitored by the EagleWatch program.
