Allen's Hummingbird

Hummingbird

Trochilidae

General appearance

Hummingbirds are small, vibrant birds with iridescent feathers. They are most noticeable for their quick, darting flying style and ability to hover in mid-air. Colors range widely, including greens, blues, purples, reds, and whites, often with a metallic sheen. They possess a long, thin beak perfect for sipping nectar from flowers.

Male vs female

Males are typically brighter and more colorful than females, often with a ‘gorget’ or patch of bright, iridescent throat feathers that females lack. Female hummingbirds have softer, muted coloration for camouflage when nesting. Males are also slightly smaller on average.

Juvenile

Juvenile hummingbirds resemble their mothers in colouring to stay camouflaged. They lack the iridescent throat patch of adult males. As they mature, juvenile males begin to develop more vibrant feathers, particularly on their throats, and by their first winter, most will have at least a few bright feathers indicative of their gender.

How to tell the Hummingbird from the Allen's Hummingbird

Visual differences

The visual differences between general hummingbirds and Allen's Hummingbird include size and plumage. General hummingbirds are 2-10 inches long and come in vibrant colors like greens, blues, and purples with iridescence. Allen's Hummingbirds measure 3-3.5 inches, boasting green and orange plumage. Allen's males feature a green back, distinguishing them from other similar species, though both genders can resemble Rufous Hummingbirds. Both species possess long, thin beaks, but Allen's Hummingbirds have a distinct, multi-pointed tail. Comparatively, general hummingbirds have varied sizes with a broader color palette.

Key differences and behavior

Hummingbirds, with over 350 species, primarily inhabit tropical areas but also adapt to urban environments during migration. They perform elaborate aerial displays during mating, after which the female independently nests and cares for the young. Hummingbirds are generalists in nectar and insect consumption, visiting a wide range of flowers. Allen's Hummingbirds, measuring 3-3.5 inches, are known for their aggressive nature and distinctive J-shaped courtship flights. They prefer semi-open habitats like brushy canyons and migrate to Mexico in winter. Allen's remember specific flower sites, feeding on a variety of colors but favoring red tubular flowers. Both species use sugar-water feeders but Allen's specifically favor red flowers. Despite these behavioral differences, both species are rapid feeders with high metabolism, requiring precise recollection of food sources.
