This list of birds of the Sonoran Desert includes all bird species endemic to the Sonoran Desert, and related areas; (a few species listed are only "native" and have a larger continental range).
The listed birds are based on the southern section of the Lower Colorado River Valley, from Yuma County and La Paz County, to the Bill Williams River, (and by extension to Needles, California/Topock, Arizona).
Bolded species are exclusive to the hottest deserts (southwestern Arizona; Baja California; northern Mexico; and the Carrizo Plain).
The southeast Arizona region is defined by: 1–the mountains of eastern Arizona, extending into western and southwestern New Mexico; 2–the sky islands defined by the NW–to–SE trending mountain ranges (formerly of the Basin and Range geology), also called regionally the Madrean sky islands; and 3–the northernmost extension of the western spine mountain range of Mexico, the Sierra Madre Occidental (West).
The result is a biome region particular to its: geographic locale, elevation, and proximity to flyways, namely for the mountains (of Mexico, the United States, and to Canada), and for the proximity to the Gulf of California, Gulf of Mexico, and the Pacific Ocean.
