To withstand the force of the oncoming air, a flight feather is shaped asymmetrically, the leading edge thin and stiff, the trailing edge long and flexible. To generate lift, a bird has merely to ...

A survey of museum specimens reveals that more than a dozen species of the birds sport biofluorescence in feathers, skin or even inside their throats.
