Adult Osprey Activity Observed:
Osprey Incubating Eggs or Chicks
Location, Date & Time of Observation:
2025-05-03

Number of Adults Visible: 2
Number of Nestlings Visible: 0

Weather Conditions: 51 degrees, no wind, clear sky but very light fog down low. Still decent visibility out as far as Round and Babson
Other Activity: 1 adult was perched on the post near the nest, and the other appeared to be incubating in the nest. Initially the light was dim, and it was hard to tell if the one in the nest was perched in the center or lying down. At one point both flew off, but returned very quickly to the post and incubating position in the nest (By then it was light enough to see well.)
Observation Method: through scope from Argilla.
