Hunters of the Feather — Victoria Grossack

Shortly after Sol hatches, his parents and nestmates discover the young crow is a gifted thinker-linker: able to communicate with distant birds, with the souls of dead birds - and even with humans! As Sol masters flight and makes his first migration, he learns many members of the Great Flock - birds all over the world - are suffering from terrible catastrophes. Fewer insects, murdered forests, even the lack of krill in the oceans: these are all caused by the ever-growing number of humans. The ancient wisdom, Adapt or die, is no longer enough, and Sol leads the hunt for a way to save birdkind from extinction. Hunters of the Feather is the first of a series, the Crow Nickels (chronicles), in which Sol joins other daring birds in a quest to save the planet.
