His research is focused on the movement, behavior, and ecology of birds during migratory stopover and modeling wildlife species distributions across spatial scales. Dr. Buler is also one of a handful of aeroecologists in the United States actively using the national network of weather surveillance radars to study the distribution, movement, and habitat use patterns of migratory birds and other flying animals in the airspace. His radar research includes developing techniques to quantify bird distributions, assessing bird response to habitat management and restoration activities, identifying important stopover areas, and examining how migrating birds respond to extreme weather events and negotiate ecological barriers to migration. He is also studying the flight activity of birds and bats at the University of Delaware’s wind turbine in Lewes, DE.
