OspreyWatch returns for its fourth year

March 25, 2015

VCU Rice Rivers Center collaborator: Center for Conservation Biology

The osprey are returning to the Northern Hemisphere this month and beginning to repair nests and reconnect with their mates. The Center for Conservation Biology’s OspreyWatch program is in its fourth year organizing citizen scientists to collect data and make observations about breeding osprey. In 2014, the project monitored 1,538 nests on three continents through the efforts of over 1,800 volunteers and researchers.

Volunteers collect data including the date when adults first arrive back at the nest (if the pair is part of the migratory population), the date that eggs are laid in the nest, the number of young seen, and the date the young successfully fledge. OspreyWatch volunteers also document the fate of nests that fail due to storm damage, nest predators (raccoons and owls), human caused nest destruction, or nest abandonment, which is important in helping researchers determine nest failure rates. Data collection on a large spatial scale enables osprey researchers to see broad trends in breeding chronology and breeding success.

OspreyWatch has helped facilitate data collection for researchers and citizen monitoring groups in Ontario, New Jersey, Florida, South Carolina, Massachusetts, Virginia, and California. The LowCountry Institute in coastal South Carolina joined OspreyWatch in 2013 and uses the website to coordinate 22 volunteers monitoring 420 nests (read their 5-yr study report). Contact program manager Libby Mojica at if your citizen science group would like to join as a monitoring group.
