Event description


Avian Vacuolar Myelinopathy (AVM) has been linked to the death for over 170 bald eagles, Haliaeeatus leucocephalus, thousands of American coots, Fulica americana, and other species of wild birds. AVM has been detected in Arkansas, Georgia, North Carolina, South Carolina, Texas, and Florida. The suspected cause of AVM is a newly characterized cyanobacterium, Aetokthonos hydrillicola that grows on submerged aquatic vegetation (SAV) such as the invasive Hydrilla, (Hydrilla verticillata), Brazilian elodea, (Egeria densa) and Eurasian water-milfoil, (Myriophyllum spicatum). This SAV/cyanobacterium contains a novel nuerotoxin consumed by waterfowl and other herbivorous taxa and can transfer up the food chain via consumption of these toxic prey items to species at the upper end of the food chain. AVM-affected birds possess vacuoles, or spaces, in the white matter of their brains and spinal cords. Clinical signs of AVM-affected birds are loss of motor coordination and inability to swim, fly, obtain food, and eventually death. Diseased birds have only been observed and collected during the winter months in a limited number of southeastern reservoirs and lakes (20 sites). The objective of this workshop is to communicate a basic understanding of the research relating to AVM, provide instructions on identifying symptoms in susceptible bird populations and outline potential consequences to endemic wildlife.
