Dr. William C. Pitt,
Research Wildlife Biologist

Dr. William C. Pitt is the field station and project leader for the USDA APHIS Wildlife Services, National Wildlife Research Center (NWRC) Hilo, HI, Field Station. His research focuses on wildlife populations, population modeling, and animal behavior of a variety of animals including rodents, snakes, lizards, amphibians, birds and mammalian predators. He completed an MS degree at Utah State University investigating the foraging behavior of piscivorous birds. His Ph.D. in wildlife ecology is from Utah State University where he studied population dynamics and foraging behaviors of grassland predators at Cedar Creek LTER site in Minnesota.  After a postdoctoral appointment developing coyote population models at the NWRC’s Logan, UT, field station, he moved to NWRC’s Hilo, HI, field station in 2002.

Dr. Pitt directs a diverse research program on invasive species throughout the Pacific Basin. He combines expertise on wildlife populations and behavior to reduce the effects of invasive terrestrial vertebrates (including rodents, mongoose, brown treesnakes, and tree frogs) on natural resources, economics, and human health and safety.   Recently, he has directed projects on the environmental effects of rodenticides on island ecosystems in Palmyra Atoll, developed pesticides to reduce environmental risk in Guam and Hawaii, assessed the potential wildlife and human health effects from anticoagulant rodenticide use, developed methods to reduce the use of rodenticides for conservation of endangered species in Palau and Hawaii, and assessed the effects of invasive species across Micronesia.  In addition to his appointment at NWRC, Dr. Pitt serves as an adjunct/affiliate faculty member at University of Hawaii and Utah State University.
