Northern crested caracara
The northern crested caracara is widespread in Sonora's lower country, including much of the Sonoran Desert, semi-desert grasslands, and thorn-scrub. It is uncommon in Arizona except on the Tohono O'odham Nation and some surrounding country. It nests often in saguaros and occasionally in tall trees. The nest is easily distinguished from other raptor nests because it is made entirely from very fine materials such as grass, never out of sticks or heavier material.
