Dr. Michael L. Avery is the Project Leader of the National Wildlife Research Center's Florida Field Station in Gainesville. He is recognized nationally and internationally for his expertise in a number of wildlife management areas including avian collisions with manmade structures (towers, powerlines, etc.); avian damage to grain and fruit crops; repellents and chemical deterrents; avian contraception methods; vulture management and roost dispersal; and monk parakeet population management. The emphasis of the Florida Field Station's current research program is on invasive species, including Burmese pythons, spiny-tailed iguanas, and common mynas.
