- The Broad-billed Hummingbird (Cynanthus Latirostris) is a spectacular summer resident in southern Arizona, recognizable by the male’s brilliant metallic green body, sapphire-blue throat, and distinct orangish-red bill - They are primarily found in riparian woodlands, lower mountain canyons, and mesquite washes - Southern Arizona marks the northernmost limit of their breeding range, where they arrive in late March and remain through September ... in winter, some may remain in the region, particularly in the lower desert and suburban neighborhoods, but most migrate south to Mexico - Top local spots to spot these vibrant birds include Madera Canyon; the Santa Cruz River in Tubac; the Sonoita Creek in Patagonia; various Southeastern Arizona Bird Observatory (SABO) sites; the San Pedro Riparian Area; and the Arizona-Sonora Desert Museum
