2020 marks the sixth season of Connecticut Audubon’s Osprey Nation citizen science project saw increases in the total number of Osprey nests in Connecticut, the number of active nests, and the number of volunteer stewards submitting data to the Connecticut Audubon Society.
However there was a decline in the number of young Ospreys that fledged from nests, from 725 in 2018 to 650 in 2019. The previous five years all showed increases in the number of fledglings.
The reasons for the decline are not clear; several years of data will be necessary to determine if a trend is occurring or if the change in 2019 was random or the result of some other cause.

The goal of Osprey Nation is to create a long-term record of data that will give the conservation community a better understanding of the health of Connecticut’s Osprey population.
