The rufous hummingbird (Selasphorus rufus) is a small hummingbird, about 8 cm (3.1 in) long with a long, straight and very slender bill. These birds are known for their incredible flight skills. Some are known to fly 2,000 mi (3,200 km) during their migratory transits.
The adult male has a white breast, rufous face, upperparts, flanks and tail and an iridescent orange-red throat patch or gorget. Some males have some green on back and/or crown. The female has green upperparts with some white, some iridescent orange feathers in the center of the throat, and a dark tail with white tips and rufous base.
The female is slightly larger than the male. Females and the rare green-backed males are extremely difficult to differentiate from Allen's hummingbird. This is a typical-sized hummingbird, being a very small bird. It weighs 2–5 g (0.071–0.176 oz), measures 7–9 cm (2.8–3.5 in) long and spans 11 cm (4.3 in) across the wings.
They feed on nectar from flowers using a long extendible tongue or catch insects on the wing. These birds require frequent feeding while active during the day and become [torpor|torpid] at night to conserve energy. Because of their small size, they are vulnerable to insect-eating birds and animals.

While visiting with my cousin in Post Falls, Idaho, I had the opportunity to join others who photograph these quick creatures. I must have taken over 60 photos, changing lenses in the middle of the 'run' of photos, and selectively cropping the good ones.
There were two of these birds, both different.

This is the resident male Anna's Hummingbird I call Lilac, this is his 5th winter with me and although it was 22F when I took this shot he is pretty active these days, the first couple winters he spent a lot of time sleeping when the temperature dropped but he is pretty seasoned now.

Hummingbirds drink nectar, a sweet liquid inside certain flowers. Like bees, they are able to assess the amount of sugar in the nectar they eat; they reject flower types that produce nectar that is less than 10% sugar and prefer those whose sugar content is stronger.
This little guy spent a lot of time at my feeders last year. He's back and I'm hoping he sticks around this year as well.

Hummingbirds are birds in the family Trochilidae, and are native to the Americas. They are among the smallest of birds, and include the smallest extant bird species, the Bee Hummingbirds. They can hover in mid-air by rapidly flapping their wings 12-90 times per second (depending on the species). They can also fly backwards, and are the only group of birds able to do so.
A female Anna's Hummingbird takes a brief rest in some blueberry bushes in the subalpine habitat of Cypress Provincial Park, West Vancouver, British Columbia. I watched a dozen or so Rufous and Anna's in this blueberry patch chasing one another for hours. It's a wonder they have any time to feed, as they chase one another 90% of the time! Talk about territorial!
