1. True or False: The hooded merganser is the largest of the mergansers and the only one of the three species found only on North America.
False. While the hooded merganser is the only of the three species restricted to the continent, according to Birds of North America online, it’s actually the smallest, weighing in at a max of just under 2 pounds.
2. How does the hooded merganser find food?
A, By sight, spotting its prey then diving underwater to grab lunch. According to Cornell’s All about Birds: “The merganser can actually change the refractive properties of its eyes to enhance its underwater vision. In addition, the nictitating membrane (third eyelid) is very transparent and probably acts to protect the eye during swimming, just like a pair of goggles.” Cool!
3. Where does the species nest?
D, in tree cavities. They will also nest in downy-lined nest boxes. The female sets up shop, scouting for an appropriate cavity the summer before a pair attempts to breed. Clutch size ranges from 5 eggs to as many as 44 (Birds of North America online).
4. True or False: The hooded merganser and the Canada goose are in the same family.
True. They both fall into the Ducks, Geese, and Swans category of the Anatidae family. The wood duck, gadwall, and 40 other species fall into this group, too.
5. What does it mean when a male flashes his hood?
B, courtship. A common use of the crest is what Smithsonian’s National Zoological Park calls the head throw. “A male raises his crest and swims parallel to a female. He throws his head back sharply until it touches his back and then brings it forward slowly while emitting a rolling frog-like croak.” What a way to wow the ladies.
