Nest Name:
ESS-11 - Dean Island Platform
Adult Osprey Activity Observed:
Osprey Incubating Eggs or Chicks
Location, Date & Time of Observation:
2026-05-25
07:10 AM to 07:25 AM
at: Essex
Number of Adults Visible: 1
Number of Nestlings Visible:
Number of Fledglings Visible:
Weather Conditions: 55 degrees, little to no wind, fog and then light rain, visibility good just to Dean and to Brophy
Other Activity: Initially it looked like the nest was empty, but a small bird landed briefly on the edge of the nest and the osprey lifted its head for a moment and then moved its head a bit. It's possible that yesterday the male was bringing in a stick and the female was just tucked way down incubating. This nest may be even bigger than Brophy now.
Observation Method: through the scope from Island Road.
