Allen’s Hummingbird Is One of the Smallest and the Prettiest Hummingbirds in North America
Allen’s hummingbird is one of the smallest hummingbirds in North America. It measures only 3 to 3.5 inches in length and weighs less than an ounce.
It is a close relative of the Rufous Hummingbird. With its beautiful colors, it is also one of the prettiest birds in North America.
The male has a shiny green or brown-green back and crown, with rufous sides and a lower back. Some males have an orange lower back.
The male’s neck is also orange-red or copper-red, with slightly extended feathers on the sides. The orange, pointy tail has dark tips.
The outermost tail feather is thin. The wings are dark-colored, and the chest is white.
The males have a white spot behind their black eyes. The females are similar to males but lack the males’ eye-catching throat stripe; their throats are speckled.
A few reddish feathers may be seen on the throats, however. The female’s chin, throat, and chest are dull white and grayish.
The upper plumage is primarily green, except for the rounded, rufous tail. Her undertail feathers are pale cinnamon.
The Allen’s hummingbird breeds in a narrow strip along the Pacific Coast, from southwestern California to southern Oregon. During migration, it reaches southern Arizona, Nevada, Texas, and Louisiana.

It Is Also One of the Prettiest...

This bird breeds from February to July. The female begins to build the nest before the mating process. Males display by flying side to side or in wide arcs while emitting a bumblebee-like buzz with their wings.
The small nest is constructed from moss, lichens, spider silk, animal hair, plant down, and other delicate materials. The females build their nests in male territory, typically on a branch between two and 40 feet above the ground.
They lay two eggs and incubate them alone for 16 to 22 days. After that, the female also takes care of the young ones entirely by herself.
The chicks fledge about three weeks after hatching and are immediately independent. Potential threats to their existence include habitat loss, pesticides, and the spread of invasive plant species.

This bird may be small, but it is also brave. Male Allen's hummingbirds will chase any other males from their territory, as well as any other hummingbird species, and have even been known to attack and drive away predatory birds several times larger than themselves, such as kestrels and hawks.
Pretty awesome, right? There is so much more than what meets the eye.
