ID tip
The calliope is the smallest breeding bird found in Canada and the United States. An adult calliope hummingbird can measure 7–10 cm (2.8–3.9 in) in length, span 11 cm (4.3 in) across the wings and weigh 2 to 3 g (0.071 to 0.106 oz). Calliope hummingbirds have glossy green on the back and crown with white underparts. The adult male has wine-red streaks on the gorget, green flanks, and a dark tail. When an adult male is competing for territory or females, the dark red feathers of its gorget distend outwards to create a more distinct appearance.
