What physical adaptation suits Wood Ducks for maneuvering into tree cavities for nesting?
Answer
Sharp claws on their webbed feet
Wood Ducks are unusual among many waterfowl species because their physical structure is adapted for a semi-arboreal existence, aligning with their nesting habits in trees. They possess sharp claws situated on their webbed feet. These specialized claws are crucial as they provide the necessary traction and grip required to balance securely on branches and successfully maneuver into the tight confines of tree cavities where they build their nests, a feat many other duck species cannot accomplish.
