NWRC Research Project: Methods Development and Population Management of Vultures and Invasive Species

BS Wildlife Ecology, University of Florida, 1992

Current Research: The emphasis of the Florida Field Station’s current research program is on invasive species, including Burmese pythons, Nile monitors, spiny-tailed iguanas, Argentine black and white tegus, and common mynas.

John Humphrey is a TWS Certified Wildlife Biologist for the USDA APHIS Wildlife Services, National Wildlife Research Center (NWRC) in Gainesville, FL.He is recognized for his expertise in a number of wildlife management areas including avian damage to grain and fruit crops; repellents and chemical deterrents; vulture management, roost dispersal, movement analysis via satellite and GSM telemetry; development and testing of management tools for Burmese pythons and Argentine black and white tegus.
