Calliope hummingbird Description

Calliope hummingbirds are monotypic (the only hummingbird in their genus). However, their wings are significantly shorter than those of closely related species, creating a sound similar to a bumblebee when in flight. Their top jaw is dull black or dusky, while their lower mandible is dusky at the end and brownish at the bottom. Those eyes are dark brown, as are the limbs and feet. They upperparts and wings are in metallic green color and white underparts. Calliopes have a shorter bill and tail than rufous hummingbirds, broad-tailed hummingbirds, and Allen’s hummingbirds, and a patch of pale buff on their breast rather than their sides and flanks.

These birds have a length of 2.75-3.25 in (7-8 cm) and a weight of 3 g (0.1 oz). Their wings could range 4.25 in (11 cm).


Calliope hummingbirds are nectarivores. They hawk insects from a perch, catching them in the air. They are known to consume flies, beetles, ants, bees, and wasps, although this behavior is rare in nature. Sapsucker-made “sap wells” have been observed by calliope hummingbirds. They probably eat insects and sap at sap wells. Hummingbirds sip nectar from blooms using their long tongues.


Calliope hummingbirds like varied habitats. They are a mountain species that ranges from 1,200 meters to 3,400 meters in height, but may reproduce as low as 185 meters. Their lengthy travels carry them through many biomes, depending on how far north or south they move. Their winter range is in southern Mexico’s rainforests, whereas their summer range is in southwestern Canada’s tundras and taigas. Calliope hummingbirds inhabit grasslands, desert and scrub woods, and alpine environments.


Calliope hummingbirds behave like other hummingbirds. During mating season, the species exclusively interacts with other members of its own species. Calliope and rufous hummingbirds may share a range. Calliope hummingbirds have been seen diving or pursuing other hummingbirds as well as bigger birds like red-tailed hawks. Annually, calliopes migrate from their summer to winter ranges. They stop frequently throughout their trip to recharge on nectar. Calliopes, like other hummingbirds, are capable of torpor, but do not do so often.
