The Rufous hummingbird is the species that lives the farthest north. It is often sighted in open terrain, high-altitude grasslands, on the edge of forests and in the shrublands of western North America, between the southern part of Alaska and California. It nests in British Columbia in the Queen Charlotte Islands, the Alaskan border and in Southwestern Alberta. A good number of them migrate through the Rocky Mountains and neighbouring lowlands. The Rufous hummingbird will sometimes make the long journey to Southwestern Yukon and Saskatchewan. Around October, they migrate to Mexico travelling more than 4000 km; a tremendous achievement given their size.
