◆非洲大象的“土葬”

动物学家曾在非洲密林深处看到有数十头大象在为死去的同伴举行葬礼。开始时,几十头象围着死去的象,好像在开会。不一会儿,象群发出哀号,为首的雄象用象牙掘松泥土,用鼻子卷起土块,朝死者身上投去,接着群象也学着雄象朝死象身上投土,很快地将死象掩埋。接着,为首的雄象用鼻子卷起土加在土堆上,并用脚踩,其它的象也跟着踩,很快修成一座“象墓”。当雄象发出洪亮呼叫,群象就停止踩踏,并有次序地绕着土堆,慢慢地走,似在举行遗体告别。直到夕阳西下,才洒泪而去。

◆南美洲亚第斯山上的秃鹰喜欢“天葬”。当同伴死后,它们就将死者的尸体撕成碎片,然后用脚爪将碎片送到大树的树梢或高山的岩洞中为其“天葬”。


补充:
◆非洲的一种獾,当同伴死后,它们就召集同类一起将死者尸体拖入附近的河水中,进行“水葬”,然后大家站在河畔哀鸣不止。

◆亚马逊河流域的一种文鸟,当同伴不幸死亡,其它同类就会叼来五颜六色的花瓣、绿叶撒在同伴的尸体上,为其“花葬”,且一只只低垂脑袋,以表示对死者的悼念

安第斯秃鹰
Andean Condor - 安第斯秃鹰

种类: 鸟类
群体名称:
食谱: 肉食
平均寿命:
尺寸: 身躯1.2米,冀展3.2米
体重: 15千克
受保护状态:濒危
小知识:安第斯秃鹰是所有鸟类中翅膀面积最大的。

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.
