Look out for September's Bird of the Month, the tiny Calliope hummingbird!

In the world of hummingbirds, where tiny jewels zip through the air with astonishing speed and agility, one species stands out for its diminutive size and vibrant plumage—the Calliope Hummingbird (Selasphorus calliope). With its iridescent green and pink feathers and distinctive whirring flight, this charming bird enchants observers lucky enough to catch a glimpse of it in the wild.

The Calliope Hummingbird is the smallest breeding bird in North America, measuring just 3–3.25 inches (7.6–8.3 cm) in length. These tiny birds breed in mountainous and forested regions of western North America, from British Columbia and Alberta in Canada, down through the western United States, into Mexico. During the breeding season, male Calliope Hummingbirds perform aerial displays to attract mates, showcasing their vibrant throat patches and agile flight. Despite their diminutive size, Calliope Hummingbirds are highly territorial and fiercely defend feeding territories and nesting sites from intruders, including larger hummingbird species.

While the Calliope Hummingbird is currently listed as a species of "Least Concern" on the IUCN Red List, it faces threats from habitat loss and degradation, particularly in its breeding range. Conservation efforts focused on protecting and restoring montane habitats, as well as providing suitable nectar sources and nesting sites, are essential for ensuring the long-term survival of this remarkable bird.
