(St. Mary’s City, MD) January 31, 2012— The planet is a noisy place, and birds can have just as much difficulty hearing and understanding each others' songs as people can have understanding each other in a crowded restaurant. Bernard Lohr, assistant professor of biological sciences at the University of Maryland Baltimore County, will discuss this phenomenon in a public lecture at 4:40 p.m. Wednesday, Feb. 15, in Schaefer Hall 106 at St. Mary’s College of Maryland.
