* Did you know the American redstart turns its eggs every eight minutes to ensure the developing bird stays warm on allsides?* Did you know the female bufflehead, the smallest of all waterfowl in North America, weighs less than a pound, or only 325 grams? The largest waterfowl, the trumpeter swan, weighs over 30 pounds or 13.6 kilograms.* Did you know that birds that spend a lot of their lives on the ocean can drink seawater? They have large glands nestled between their eyes that remove excess salt from the blood.* Did you know at least 32 species of birds are known to eat snakes? Even the American robin has been seen feeding young garter snakes to its babies.
