Other Activity: One on nest upon arrival. Around 2:55 another flew in. It circled along time and made a few dives but pulled up each time. It was still circling when I left. The water was choppy (for Collins Cove) and I wondered if it was hard for the Osprey to see fish. Meanwhile the one on the nest stayed put. Incubating???
Observation Method: On foot, binoculars, from across the cove
