Why did the ornithologist strap a taxidermy badger to a remote controlled car and drive it around the prairie? To interrogate the secret world of animal eavesdropping in the grasslands, of course! Today on the show, we travel to the most imperiled ecosystem on the planet to unravel a prairie mystery and find out why prairie dogs are grassland engineers worth keeping tabs on.

Special thanks to Andrew Spencer and the Cornell Lab of Ornithology for providing the Long-billed Curlew call recording, and to American Prairie for providing prairie soundscape recordings.
