Phys.org Reports on Olsen’s Research on Sexual Selection of Birds
Phys.org reported on research on the sexual selection of birds conducted by Brian Olsen, assistant professor in the University of Maine’s School of Biology and Ecology and Climate Change Institute. Olsen found when looking for a mate, female coastal plain swamp sparrows choose males with large bills. He also found small-billed males are more at risk of being cheated on by their mates.
