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。
Rock Pigeon
The rock pigeon is the ancestor of all domestic pigeon breeds and one of the most abundant birds in cities worldwide. Pigeons have served humans as messengers, food, and subjects for scientific research — their homing ability and vision have been studied extensively. Darwin's study of pigeon breeding contributed to his theory of evolution.
