Last week, about 20 dead black vultures were discovered at the entrance to Fisherman's Park at Conowingo Dam. They were sent to a laboratory for testing. "We tested them for highly pathogenic Avian Influenza, and they did test positive," said state veterinarian for the Maryland Dept of Agriculture Dr. Michael Odian. Odian said they are working with the Department of Natural Resources, Maryland Dept of the Environment and USDA to contain the disease by removing carcasses before other vultures eat them. "The black vultures are carnivorous," said Odian. "When a non-sick vulture eats the sick vulture, it infects itself." https://www.cbsnews.com/balt…
