Noah Perlut, Ph.D., assistant professor in the Department of Environmental Studies, recently published an article in the journal The Auk: Ornithological Advances. Co-authors include Steven Travis, Ph.D., associate professor in the Department of Biology; Catherine Dunbar, a former Animal Behavior major; and Derek Wright, a former environmental science major.
The article, “Nestling sex ratios do not support long-term parity in two species with different life-history strategies,” explores the sex ratios of young in two species of grassland nesting songbirds that breed in agricultural fields in Vermont.
Results demonstrated that while Savannah Sparrows showed a significant female-biased nestling sex ratio, Bobolinks’ sex ratio was even.
