My money is on the Ospreys for a couple of reasons. I think it was last year I
saw a similar thing happen at the Union Fields nest: a couple of Fish Crows
were poking around the Osprey nest before the Ospreys had settled in. I don’t
know what the Fish Crows were doing, but they weren’t serious
A pair of Fish Crows also seems to have taken up residence on the Osprey nest
pole at the west side of Stewart Park, next to Fall Creek. It will be
interesting to see what happens once the Osprey pair arrives! I did see one
Osprey along the creek this morning, but none at the nest sites yet.
