A burrowing owl guarding its burrow at Casa Grande Ruins.

Burrowing owls are unique among birds because they nest underground in existing ground squirrel, coyote, and badger burrows. They are also commonly associated with humans and will frequently nest in burrows along irrigation ditches, canals, and even in people’s yards.
