Ruby Throated Hummingbirds

Quick – can you think of a bird that can fly backwards? I’m Jim Metzner, and this is the Pulse of the Planet.
ambience: Ruby-throated hummingbird’s wings
Appearance-wise, they’re a little on the frenetic side, and they’re name comes from the sound that we’re hearing right now: the beating of their wings. Hummingbirds. They can beat up to 200 times per second, giving them the unique ability of flying backwards, and of hovering in place.
A male hummingbird’s wings beat the fastest when he’s courting a female, and that’s what many of them are doing this week, across the eastern half of the United States.
Ruby-throated hummingbirds – the species we’re listening to now, travel almost 2000 miles north from the tropics; that’s quite a trip for a bird that’s only about four inches long. By now most of the males have established their territory, and all they need is a female, or several females, to mate with. Once that’s done, it’s the female’s job to build the nest, which is a cup around one inch across, and to tend the eggs. She lays about two, which will eventually hatch into birds that are smaller than your fingernail.
The ruby-throated hummingbird get its name from, not surprisingly, the blood-red feathers in the male’s throats. These delicate birds appealed so much to turn-of-the-century aristocrats, that they often had them stuffed and used as a mantelpiece decoration. Thankfully, that practice has ended, and the ruby throated hummingbird can still be prized at this time of year by backyard birdwatchers.
