We used to raise Muscovys (they are delicious, and the eggs are incredible, too). It always cracked me up how the females are so much smaller and look like normal ducks, while the males are these hulking, wart-covered monstrosities. And I love how they pump their necks when they swim or walk.

Also? They have NASTY claws, because the species form (non domesticated) are tree-perching ducks. Even our domestic hens would occasionally take to the trees at night, rather than the barn. The males were too big to get airborne.

Crazy.
