Non-Migrant: No. All populations of this species make significant seasonal migrations.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: Yes. At least some populations of this species make annual migrations of over 200 km.
Route from Mexico to Alaska is longest migration of any North American hummingbird (True 1993). Stopover habitats are critical for accumulating resources required for migration.
Migration patterns coincide with weather patterns and flowering times (Calder 1993). Rufous hummingbirds migrate northward along the Pacific Coast and through lowlands west of the Rockies in winter and early spring (Calder 1993), arriving in California in late February-early March, Oregon by March 1, Alaska by mid-April. Southward migration is chiefly through mountains of Cascades/Sierras and Rocky Mountains. Southward migrants were observed in Colorado over a 6-week period in July and early August (Calder 1993). Arrival in southern Arizona/New Mexico occurs by late July/August and in central Mexico by August/September (Baltosser 1989; Calder 1993). Males migrate before females and juveniles (Phillips et al. 1964).
