BirdNote Special: Alex Chadwick in Big Bend

In this new four-part series of features, Alex Chadwick heads to Southwest Texas to find out just what it is that draws people to Big Bend, one of the most remote national parks in the entire United States. It's not just people either. 450 species of birds have been recorded in the park at one time or another, including roadrunners, Baird's Sparrows, and hummingbirds -- all of which play a role in Alex Chadwick's four features. We hear the story of a roadrunner that didn't get the memo about the Baird's Sparrow being a rare, almost protected species; about the attractions of collecting data on hummingbirds and how for one naturalist, that practice connects all the way back to John James Audubon. And we hear about one woman's relationship with water in a place of challenging habitats.
