The Calliope Hummingbird (Selasphorus calliope) is a mountain-loving species and prefers habitats from 4,000 to 11,000 feet in elevation. They are often found near the timberline (the elevation where trees stop growing) in evergreen forests, along streams, aspen groves, and in second growth forests that have been clear-cut or burned. Calliope Hummingbirds can frequently be seen in urban areas during migration as they visit feeders and use flowering eucalyptus trees.Link to non-FWS site.

Adult Calliope Hummingbirds migrate northward in the spring from Mexico through the western United States to breeding grounds in northern Baja California and southern California north to southern British Columbia, and east to Montana, Wyoming, and Utah. The female is the primary caretaker for the young. The Calliope Hummingbird only has one brood (group of young) per season, typically with two hatchlings. It takes about 15 to 16 days for the eggs to hatch, and then the young remain in the nest another 18 to 21 days. Breeding season usually lasts from mid-May to July. Males migrate south a few weeks before females and juveniles. The Calliope Hummingbird typically lives five to six years.

Adults feed on flower nectar, small insects, and tree sap, and will regularly use hummingbird feeders. They use many different plants including red currant (Ribes triste), Indian paintbrush (Castilleja spp.), orange honeysuckle (Lonicera ciliosa), western columbine (Aquilegia formosa), skyrocket (Ipomopsis spp.), Rocky Mountain bee plant (Cleome serrulata), beardtongue (Penstemon spp.). They also use flowers not usually associated with hummingbirds such as yellow monkey flower (Mimulus tilingii var. caespitosus), lousewort (Pedicularis semibarbata), snow plant (Sarcodes sanguinea), and pine-mat manzanita (Arctostaphylos nevadensis).
