American White Pelicans have beautiful black feathers that are only visible when they unfurl their wings. While their body is squat, their wings can span 9 feet! Look at the top of the bill of this bird and you can see a plate or "horn" forming. After breeding and laying eggs, this will fall off.

White pelicans soar high,
Over Gulf waters they glide,
Texas coast in sight.
