Glyde, Gonzo, and Azul have one thing in common: they’re all flying as flocks of one. Other than his father, Lupé, Glyde has never seen a pure Guadalupe petrel, so when he hears of a similar petrel in danger, he implores his father to join him in a daring rescue attempt. Along the way, Glyde is joined by Gonzo, an endangered ivory-billed woodpecker, Zomis, the last remaining passenger pigeon, and a barred owl who speaks only in Shakespearean English.

Meanwhile, after losing his mate and being smuggled out of the shrinking Caatinga, Azul finds himself in the care of a celebrated conservationist. However, not everything is as it seems, and the Spix’s macaw must fight to return to the place he knows best. But with a disappearing habitat and without a mate, can his journey lead him home?

The John Morano Eco-Adventure Series is back with a fourth installment that asks the question: What does it mean to be home in a changing world? As the climate warms and habitats are lost, will the man-flock help the birds before it's too late, or will these flocks of one become flocks of none?

Featuring a special introduction by Andrew Sharpless, CEO of Oceana.
