The grassland birds that bring sweet song to North America's prairie are in decline, with habitat loss, land degradation and climate change threatening what's left of a once-vast ecosystem.
Over half the grassland bird population has been lost since 1970, and one-quarter of the species are in extreme peril. It's a situation that biologists, conservation groups, farmers and ranchers would like to reverse — so they're teaming up to do so. That means ramping up efforts to tag birds, track them, and foster best practices for land use that can aid their survival.
