About These Birds
American Robin
美洲鸫(学名Turdus migratorius)被广泛视为北美春天的使者。尽管名为"知更鸟"(robin),实为鸫科(Turdidae)成员,与欧洲知更鸟无近缘关系。雄鸟胸部橙红色,头部黑色,体长约25厘米。食蚯蚓和浆果,常见于草坪和公园。
King Penguin
The king penguin is the second-largest penguin species, known for its striking orange-gold head markings. Unlike most penguins, king penguins do not build nests — they incubate their single egg on their feet. Their 14-16 month breeding cycle is the longest of any penguin species.
