Shelagh T. Deliberto is a Wildlife Biologist with the USDA APHIS Wildlife Services, National Wildlife Research Center, Fort Collins, CO. Her areas of expertise includes avian conservation and ecology, and wildlife damage management. Her primary focus has been on evaluating the efficacy of repellents and other non-lethal methods to reduce bird damage to agricultural crops. She has also conducted research related to avian use of utility structures and avian perch deterrents. Currently her research focuses on repellent application strategies and novel applications of current technology to existing human-wildlife conflicts.
