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。
Northern Cardinal
The northern cardinal is the state bird of seven US states, more than any other species. Unlike many songbirds, both males and females sing, often in duets. Cardinals do not migrate and their brilliant red plumage against winter snow makes them a favorite among backyard birdwatchers.
