Birds: Episode Description![]() More LifeBirds have one feature that no other animal possesses: feathers. This allows them to solve life's challenges in radically different ways.
The male spatule-tail hummingbird performs extraordinary aerial displays, using fast-beating wings and super-long iridescent tail feathers. The red-billed tropic bird uses its incredible agility to outmaneuver attacking frigate birds in a high-speed aerial "dogfight."
Red knots migrate 10,000 miles every spring from wintering grounds in Argentina to nesting sites in Canada; and Antarctica's chinstrap penguins make an exhausting climb up the steep flanks of a glacier-covered volcano to get food to their chicks.
Birds also use color, song and ingenuity to win the hearts of their mates: Clarke's grebes perform a courtship dance that climaxes with the pair running on water in perfect synchrony; the male Vogelkop bowerbird employs bizarre rituals to impress a female; and in Kenya, 1,000 flamingos promenade side by side with neck feathers ruffled and heads held high.
