Kansas is the 15th largest and 35th most populous state in the United States. Large plains, rivers, and state parks are prominent features. The American Buffalo is the state animal of Kansas, but what is the Kansas state bird? The Western Meadowlark is nearly 9 inches long. An orange-yellow chest with a black V distinguishes its back and wings. In the dead of winter, the Meadowlark’s plumage may be drab. Its long, pointed bill is one of their most distinguishing features.
