2007-12-13, Rock Wallaby - 澳洲岩间袋鼠（在线收听） |
| This little kangaroo is a yellow-footed rock wallaby. They show off their mountaineering skills wherever cliffs jut out (of) Australia's vast desert land. Living in large colonies, the rock wallaby shelter in caves along the rocks. Shady crevices harbor vegetation year-round. But water can be a problem. To get it they sometimes descend to where rain collects below. But they must keep an eye out for wedge-tailed eagles. Youngsters waiting on the cliffs sometimes wander into the open. Only adults descend to drink. Young ones too big for the pouch must stay behind. In just a few minutes she will drink 1/10 of her weight in water. Then she will hurry back to her joey. Thirsty joeys drink straight from mother's mouth. Once satisfied they gracefully hop back to the safety of their mountain hideaways. |
