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。
Atlantic Puffin
The Atlantic puffin, often called the clown of the sea, is a charismatic seabird that nests in burrows on northern sea cliffs. Puffins can carry up to a dozen fish crosswise in their beaks at once thanks to backward-facing spines on their palate. Climate change and overfishing are threatening their food supply, leading to population declines.
