Broad-Tailed Hummingbird

Allen's Hummingbird

Selasphorus sasin

General appearance

The Allen's hummingbird is a small species, measuring between 3-3 1/2" (8-9 cm), roughly the size of a Sparrow. The bird displays a variety of colors including black, green, orange, red, and white. Its physical features consist of a multi-pointed, rounded, and wedge-shaped tail, with narrow, rounded and short wings.

Male vs female

Mature males have coloration similar to a Rufous Hummingbird, with the notable distinction of a green back. However, Rufous Hummingbirds can also display green backs making identifying Allen's challenging outside of their typical range. The females and young of the species are completely identical to their Rufous counterparts.

Juvenile

The juvenile Allen's hummingbirds inherit the identical appearance of the female and are similar to Rufous younglings, so identifying them can potentially be difficult. Instead, their range of habitat can provide a decent clue towards proper identification.

How to tell the Allen's Hummingbird from the Broad-Tailed Hummingbird

Visual differences

Allen's Hummingbirds are smaller, measuring about 3-3 1/2 inches, compared to the Broad-Tailed Hummingbird's 4-4 1/2 inches.

Female Broad-Tailed are larger with buff sides, unlike the smaller Allen's females. Both species have narrow, rounded wings, but the Broad-Tailed has a notched, square-tipped orange tail. Allen's tail is multi-pointed and wedge-shaped.

Key differences and behavior

Allen's and Broad-Tailed Hummingbirds exhibit distinct behaviors and preferences. Allen's Hummingbirds, weighing 0.07-0.14 ounces, are notorious for their aggression and excellent memory of flower locations. They thrive in semi-open areas and migrate to Mexico in winter, performing a J-shaped flight during courtship. Broad-Tailed Hummingbirds, slightly heavier at 0.11-0.14 ounces, breed in high-altitude open forests, showcasing elaborate aerial displays with distinctive wing sounds for courtship. Both species consume nectar and insects, favoring red tubular flowers, but Allen's Hummingbirds are highly aggressive at feeders. Their nesting behaviors are similar, with females solely incubating eggs and feeding chicks, though Broad-Tailed Hummingbirds favor montane meadows. Allen's Hummingbirds prefer lower altitude semi-open habitats compared to the mountainous regions of Broad-Tailed Hummingbirds.
