Podiceps cristatus hatch eggs 凤头鸊鷉孵蛋

The great crested grebe (Podiceps cristatus) is a member of the grebe family of water birds noted for its elaborate mating display. The great crested grebe has an elaborate mating display. Like all grebes, it nests on the water's edge, since its legs are set relatively far back and it is thus unable to walk very well. Usually two eggs are laid, and the fluffy, striped young grebes are often carried on the adult's back. In a clutch of two or more hatchlings, male and female grebes will each identify their 'favourites', which they alone will care for and teach. 月春暖花开。凤头鸊鷉是一种游禽，亦称冠鸊鷉，俗称浪里白。为冬季候鸟。栖息于沿海地区、湖泊、水库、江河等水域。其食物鱼、虾、水生昆虫、部分水生植物。常成对或小群活动。善游泳、潜水，不善飞行。其巢多位于浅水处的水草间。是体形最大的一种鸊鷉，雄鸟和雌鸟比较相似，有鸭子一样大小，嘴又长又尖，从嘴角到眼睛还长着一条黑线。它的脖子很长，向上方直立着，通常与水面保持垂直的姿势。通常营巢于距明水面不远的芦苇丛和水草丛中。成对分散营巢或成小群在一起营巢，巢属于浮巢，飘浮在水面。通常弯折部分芦苇或水草作巢基，再用芦苇和水草堆集而成。
