The discovery of dead black vultures around Fisherman's Park near Conowingo Dam has spurred a shuttering of nearby trails due to bird flu concerns. Constellation, the energy company operating the dam, reported the findings and took swift action in collaboration with Maryland's Department of Natural Resources (MDNR) to conduct avian influenza testing on the carcasses, as detailed by WMAR-2 News. Fisherman's Park trails, such as the Wildflower and Mason-Dixon between the Overlook parking area and the park itself, are temporarily closed. In contrast, the dam's fishing wharf has yet to experience similar reports of deceased birds.

WMAR-2 News reported on the situation, noting that after the MDNR confirmed bird flu in the found vultures, Constellation has intensified efforts to safeguard park visitors. Constellation announced, "MDNR to help protect the public and wild birds in Fisherman’s Park, including the area’s beloved eagles," showing recognition of the broader ecological significance of the issue.

Adding to the closure of hiking trails, The Baltimore Banner highlighted the involvement of multiple state and federal agencies in combating the avian flu threat following the discovery of dozens of dead vultures near the park. "Carcasses are collected daily," Constellation spokesperson Brandy Donaldson informed The Baltimore Banner, signaling a proactive response to prevent further spread. Although it's not yet confirmed that bird flu is the cause of death for these vultures, it remains the prime suspect, with test results pending.
