   Why Flamingos Are Pink

   Flamingo chicks hatch grey, not pink. Here's how they get their famous color from what they eat, how pigments travel from tiny algae and shrimp into their feathers, and what a flamingo's shade of pink can signal to other flamingos.

   What Birds See in Ultraviolet

   Birds see colors we can't. With an extra kind of color cone, many birds see ultraviolet light, which reveals hidden patterns on feathers, fruit and eggs.

   How Small Birds Survive a Winter Night

   On a freezing winter night, a bird that weighs less than an ounce has to make it to morning.

   How Hummingbirds Hover

   Hummingbirds are the only birds that can hover again and again, all day long. Here's how they do it: wings that are mostly hand, strokes that lift on the way back, oversized muscles, a sugar-powered engine, and eyes that keep them locked in place.
