Neotropical migratory songbirds spend the winter in Central and South America and travel each spring to their breeding grounds in the U.S. and Canada. These species are teeny creatures on average, often weighing under two ounces each, yet their travel plans are bold — some make roundtrips of more than 10,000 miles in a single year. But this colorful cohort of birds, from warblers to thrushes to tanagers, face habitat loss from climate change and development at both ends of their range.

But the Big Ivy region of the Pisgah National Forest in North Carolina is a rare intact forest that provides a welcoming breeding ground for many of these birds, including species whose outlook has been especially bleak. This episode, host Jennifer Errick speaks with NPCA Southern Appalachian Director Jeff Hunter and Wildlife Research Program Coordinator Steve Goodman on the 415,000 birdsongs they’ve captured in the Big Ivy and how they’re using the beautiful recordings to protect this rare and beautiful Appalachian forest.

The Secret Lives of Parks is a production of the National Parks Conservation Association.

Episode 46, The Bird Nerds of Big Ivy, was produced by Jennifer Errick, with help from Todd Christopher, Bev Stanton and Linda Coutant.

Original theme music by Chad Fischer.
