Touraco, tur uh KOH, or turaco, is any member of a family of African birds that live south of the Sahara. These birds measure from 15 to 30 inches (38 to 76 centimeters) long. Many of them have bright green, red, and violet-blue feathers. Touracos are the only birds that produce a green pigment (coloring matter) in their feathers. The green color in other birds results from the reflection of sunlight by the feathers.
