New episode - Black Swifts in Winter
A new episode is available to subscribers: Black Swifts in Winter.
On this episode of OutBirding with Field Guides, Bret Whitney retraces the discovery of the mysterious wintering grounds of the Black Swift, from their nesting areas in the Colorado Rockies to deep in the heart of South America. We’ll visit with some of the researchers who designed the landmark geolocator study that finally revealed the winter whereabouts of these fantastic birds. It was on a boat-based Field Guides tour in central Amazonia that Bret and the tour group corroborated the Colorado geolocator data with real-time video, documenting the physical presence of Black Swifts wintering in Amazonian Brazil.
