Birds were hand captured at or near impoundments (cells) and ponds that contained large algal blooms, and because of poor prognosis were euthanized. Seemingly healthy great blue herons were subsequently collected at Blackwater National Wildlife Refuge.

Liver samples were analyzed [...]

These data were collected as part of a wildlife mortality event occurring at a time when harmful algal blooms were detected in parts of the Chesapeake Bay. These data help guide the development of a study proposal.
