Three endangered birds-a trafficked Spix's macaw, a supposedly extinct ivory-billed woodpecker, and a lonely petrel-embark on separate journeys that will redefine survival. As extinction looms and habitats vanish, these "flocks of one" discover that connection across species might be their only hope. From Brazil's Caatinga to the Pine Barrens to remote islands, their interwoven stories of sacrifice, friendship, and resilience ask: when you're the last of your kind, what does it mean to have a flock? A powerful eco-adventure about finding family in unexpected places. Featuring a special introduction by Andrew Sharpless, CEO of Oceana.
