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。
Belted Kingfisher
The belted kingfisher is unusual in that the female is more colorful than the male, sporting an additional rufous belly band. These noisy birds announce their territory with a distinctive rattling call. They excavate nesting burrows up to 2.4 meters deep into riverbanks using their heavy bills.
