Sol, a thinker-linker crow, learns the Sky Council's decision about the humans who are making the planet unlivable for so many species of birds: instead of adapting or flying away, the Great Flock will fight. But what does this mean? And how can birds, who are so much smaller than humans, do anything to fight the humans and their powerful machines? In their search for answers, Sol, his sister Ava and his dead brother Peeps approach many different birds until they discover a way that just might work to reduce the large number of humans on the planet. They collaborate with the magpies on the project, but Sol begins to have more and more misgivings about the attempts to kill the humans.

Scavengers of Mind is the second of a series, the Crow Nickels (chronicles) in which Sol joins other daring birds in a quest to save the planet.
