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。
Black Swan
The black swan was once considered impossible by Europeans who believed all swans were white, making it a famous philosophical example of inductive reasoning failure. It is the state emblem of Western Australia. Black swans form lifelong pair bonds and both parents share in incubation and care of cygnets.
