安第斯禿鷹

安第斯禿鷹

安第斯禿是一種龐大的鳥類,它們是世界上最大的可飛翔動物之一。因為它們過於龐大(最重可達15公斤),所以即使是3米的翼展也需要一樣幫助才成。因此,這種鳥樂於生活在多風的區域,這樣它們就可以在上升的熱氣流中省力滑翔。正如它們的名字所暗示的,安第斯禿鷹多見於山地,但是也有些生活在多海風的海岸,甚至在多熱氣流的沙漠地帶。

外形特徵

安第斯禿鷹是所有鳥類中翅膀面積最大的。安第斯禿鷹一般都是黑色的,雄性頸部有一個特別的白色“領結”,它們翅膀上有白色的標記。跟它們的親屬加州禿鷹一樣,安第斯禿鷹也是禿頭。安第斯禿鷲是一種瀕臨滅絕的肉食猛禽鳥類,身軀1.2米,冀展3.2米,體重15千克左右,平均可達壽命72歲。

生活習性

安第斯禿鷹是腐食動物,所以它們始終在高空飛翔中尋找動物屍體來果腹。它們喜歡食用大型動物,不論是野生的還是家養的。它們在自然界中擔任著清潔工的重要職責。生活在海岸的禿鷹食用死去的海洋動物,例如海豹或者海魚。安第斯禿鷹沒有利爪,不過有時候它們會襲擊鳥巢獲取卵甚至幼鳥。

繁殖方式

這種長壽的鳥類能活75年,有些甚至能活100歲,不過它們繁殖很慢,一對雌雄一年只能生出一隻幼鳥,而且父母都得照看幼鳥一整年。

英語介紹

Andean condors are massive birds, among the largest in the world that are able to fly. Because they are so heavy (up to 33 pounds/15 kilograms), even their enormous 10-foot (3-meter) wingspan needs some help to keep them aloft. For that reason, these birds prefer to live in windy areas where they can glide on air currents with little effort. Andean condors are found in mountainous regions, as their name suggests, but also live near coasts replete with ocean breezes and even deserts that feature strong thermal air currents.
These condors are mostly black, but males have a distinctive white "collar" around their necks and some white markings on their wings as well. Like their relatives, the California condors, Andean condors have bald heads.
Condors are vultures, so they keep their sharp eyes peeled for the carrion that makes up most of their diet. They prefer to feast on large animals, wild or domestic, and in picking the carcasses, they perform an important function as a natural clean-up crew. Along the coasts, condors will feed on dead marine animals like seals or fish. These birds do not have sharp predator's claws, but they will raid birds' nests for eggs or even young hatchlings.
These long-lived birds have survived over 75 years in captivity, but they reproduce slowly. A mating pair produces only a single offspring every other year, and both parents must care for their young for a full year.
The Andean condor is considered endangered but is in far better shape than its California cousin. Perhaps a few thousand South American birds survive, and reintroduction programs are working to supplement that number.
