The 11am hour of today's Diane Rehm Show on National Public Radio is dedicated to the topic of birding and to a couple of new bird guides.  In the DC area the program can be found on the flagship station, WAMU 88.5.

Archives of the show are available on the website a couple of hours after the program ends.
