The Chapel Hill Bird Club will hold its regular monthly meeting on Monday, October 26, at 7:30 pm at Binkley Baptist Church in Chapel Hill. The featured speaker will be Irene Liu, who will give a presentation entitled “Sex, Lies, and Videotaped Blackbirds.” Biologists used to think copulation was the finish line for an animal’s reproductive success, but we now know that sperm of different males often compete to fertilize a female’s eggs. Advances in DNA sequencing mean we can examine this competition on the genetic level. How does this post-mating competition drive the evolution of a species? Irene Liu studied the behavior and genes of three North American blackbird species to answer this and other questions.
