川秋沙〔普通秋沙〕

<em>Mergus merganser</em>, the common merganser or goosander, is a large diving duck in the family Anatidae, broadly distributed across Europe and North America. It is classified as Least Concern on the IUCN Red List. This species is capable of aerial, terrestrial, and aquatic locomotion, but is most specialized for underwater pursuit of prey. The common merganser is typically piscivorous, diving in clear, fast-flowing rivers and lakes to catch fish using its serrated bill, which provides a firm grip on slippery prey. Males display striking breeding plumage with a dark green head, white body, and red bill, while females are grey with a rusty-brown head and crested nape. The species nests in tree cavities, cliff ledges, and artificial nest boxes near freshwater habitats. It requires clean, well-oxygenated rivers and lakes for foraging, making it sensitive to water quality degradation and overfishing of prey species. Common mergansers are migratory in northern parts of their range, moving to coastal and ice-free inland waters during winter months.

giraffe

长颈鹿（Giraffa camelopardalis）是地球上最高的动物，身高可达5.5米，体重最重可达1,750千克。其细长的颈部——与所有哺乳动物一样包含七块颈椎——是为了在非洲稀树草原和林地取食金合欢树而进化的。长颈鹿是社会性动物，生活在无固定纽带的松散兽群中，通过次声波和肢体语言进行交流。由于栖息地丧失和偷猎，种群持续减少，被列为易危。
