Calls a low tchup and an excited, buzzy zeee-chuppity-chup; very similar to calls of Allen's Hummingbird. The wings of adult males may produce a musical buzz in flight.
Breeds from southern Alaska, southwestern Canada, and western Montana, south and west of Cascades to northwestern California and southern Idaho. Winters mainly in Mexico. Often strays out of usual range.
Found in coniferous forests, second growth, and thickets and brushy hillsides (forages in adjacent scrubby areas and meadows). During migration and in winter, found in open situations where flowers are persent. A study in north-central Idaho found these hummingbirds more common in clearcut areas than in fragmented or contiguous stands of coniferous forest.
Feeds on nectar, insects, and tree sap.
Builds nest in tree, often on drooping branch; occasionally nests on vine. May nest in loose colony of up to 10 nests. Defends feeding territory during migration and on breeding grounds. Capable of altering energy balance by employing Nocturnal torpor.
Female lays 2 eggs. Young are capable of first flight about 20 days after hatching.
