Dr. David Pearson - Bird behavior and mating choice

Tuesday, December 14, 2021
7:00pm – 8:00pm

Some birds mate for life, most are monogamous for at least a season, but some are polygynous, and a few outliers are polyandrous (female with numerous mates). What ecological factors determine which mating system works best for each species? Are females in charge of mate choice? We will also discuss if human mating systems reflect some of the same causes as birds.

Dave Pearson is a professor at ASU where his research has focused on using the interaction of ecology, conservation, ecotourism and education to develop methods that promote sustainable use of biodiversity. He has worked on a breadth of organisms from crabs to insects, and Paramecium to birds. He has also studied a range of habitat types including coral atolls and desert grasslands. He has a PHD from the University of Washington.
