Fulica americana
The American Coot is a delightful blend of comedy and confusion. This member of the rail family appears to have been made from leftover pieces of other birds: it has the bill of a chicken, the feet of a grebe and the body of a duck. When coots swim, their heads rock back and forth in direct synchrony with their swimming speed. American Coots are constantly squabbling with one another. They can often be seen running across the surface of the water, charging rivals and attempting to intimidate them. The distinctive calls of American Coots can be heard echoing across wetlands throughout the warmest months. Coots are also colloquially known as Mud Hens. |
