Rufous Hummingbird

Rufous Hummingbirds breed from Alaska and Western Canada to the northwstern United States. The are the most northern-breeding hummingbird. Alaskan birds have a short breeding season but exceptionally long days. Rufous Hummingbirds have an eliptical migration route—up the West Coast in the spring, but furthern east, through the wildflower-laden Rocky Mountains in the late summer. In British Columbia, most males begin their fall migration by early July, moving up to higher elevations. Females follow after their young fledge (Healy and Calder 2000). We photographed this immature bird in Olympia, Washington, on 5 July 2019, In Washington, males appear in early March, followed by females in the next couple of weeks. Numbers decline in August, becoming uncommon by September (Wahl et al. 2005).
