Black-Bellied Whistling Ducks - just can't let Christmas come and go without letting them wish everyone a Merry Christmas.
They are second only to the Laughing Gull on my favorites list. They remind me of the little green Martians that are toys in the Toy Story movies. They act as a unit, one for all, all as one. They can't think outside their box, they're noisy, if one moves, they all move, and most unusual for a duck - they don't really like to get in the water.
