Kim Todd

The Connecticut-based show runs from 1-2 p.m. and can be heard at birdcallsradio.com. The hosts are North East native Chris Bosak and Mardi Dickinson.

Todd is the author of “Sparrow,” which delves into the history, biology and ecological impact of the House Sparrow. She also wrote 2001’s “Tinkering with Eden, A Natural History of Exotics in America,” which examines species such as the European Starling, Rock Pigeon and Gypsy Moth.

Sunday’s discussion will turn toward the pros and cons of introducing species to the United States. E-mail your questions in advance.

She has taught environmental and nature writing at the University of Montana, the University of California at Santa Cruz extension, and the Environmental Writers Institute. She also will speak Aug. 4 at the Harvard Museum of Natural History and Aug. 5 at the Audubon Society of Rhode Island in Bristol, R.I.
