gardening, the environment, green living and a lot of humor

Naturalist and author Joel Greenberg discusses his new book, A Feathered River Across the Sky: The Passenger Pigeon's Flight to Extinction, published 100 years following the death of the last passenger pigeon in the world. He talks about his work with Project Passenger Pigeon and the lessons learned since the bird, which once numbered in the billions, was extirpated as a result of relentless hunting.
