Episode description

The incredible variety of bird song in a morning chorus on a spring or summer day is a phenomenon that a lot of birders are familiar with. But even after centuries of study there is still a lot we don’t know about bird vocalizations, especially the world of female birdsong. The vocalizations of female birds are frequently as complex and important to the lives of birds as the songs we associate with male birds, and it’s only relatively recently that we’ve begin to really look into that. Dr. Lauryn Benedict, from the University of Northern Colorado, has been on the cutting edge of this science and she joins me to talk about bird vocalizations and other aspects of female bird biology. 

Also, Kirtland's Warbler is off the Endangered Species List and what is birding like after LASIK surgery.
