I received a report on April 2 that the power plant osprey nest had been appropriated by a pair of peregrine falcons. I checked it out today, and the report is true. The osprey are reportedly building a new nest on the other side of the River. When I can confirm this, I will enter info for the new nest on a new record.

2015 - Osprey pair arrived much later than usual, and had to almost completely rebuild nest due to winter storm damage. At least 2 young were observed in the nest in June, and at least one fledged by mid-July. I did not manage to visit this nest much this season, but a friend reported that fledging occurred.

Briefly checked the site this morning. I saw one Osprey on the nest.

Observed all three fledglings and one parent bird on or near the nest today.

Visited the nest today. Saw three chicks. Stayed until 1755 and watched the female feeding the chicks pieces of a fish. Pulled the long lens out and took many photos.

I also scoped this nest today. Female is still incubating.

4/11/13 - Observed nest from York Haven side of the river. Female is incubating, male was perched on rooftop sign, with a fish clutched in his talons upon our arrival. At one point he flew to the nest with the fish, but several minutes later left still carrying it and returned to rooftop. An adult bald eagle and numerous turkey and black vultures were flying overhead; the ospreys did not appear disturbed by them.

April 9, 2013, female is clearly in incubation posture. Male is standing on edge of nest beside her.

04/10/2013 by Westwindschild
On visits on March 31, April 3, and April 5, female was near or on the nest, but not in flat profile. On one occasion, I can't recall now if it was the 3rd or the 5th, but one of the two dates, female appeared to be rolling an egg in the nest.

March 23, 2013, observed one osprey working on fixing up the nest, which was in bad repair following winter's storms.

04/10/2013 by Westwindschild
First observed osprey activity in 2013 on March 20. There had been no sign of activity as recently as March 17, so I am dating their return from migration on the 20th.
