Osprey nests in Chesapeake Bay face new challenges

Ospreys in the Chesapeake Bay are facing breeding issues, possibly linked to a decline in their primary food source, Atlantic menhaden.

Timothy B. Wheeler reports for Bay Journal.

In short:

Researchers found that ospreys in the Chesapeake Bay have a lower reproductive rate, with many nests failing to produce young, possibly due to a lack of Atlantic menhaden.
The Atlantic States Marine Fisheries Commission is studying the potential impact of commercial menhaden harvesting on osprey breeding and fish populations in the Chesapeake Bay.
While some scientists suggest food scarcity is affecting ospreys, the overall population is not in immediate danger due to their long lifespan and ability to withstand temporary reproductive dips.

Key quote:

“A high proportion of failures after hatching and a larger proportion of one-chick broods is a clear sign of food stress.”

— Bryan Watts, director of the Center for Conservation Biology

Why this matters:

Ospreys rely on fish as their main food source, making them indicators of fish abundance. Their breeding success can signal changes in fish populations and ecosystems, affecting biodiversity and local fisheries.
