The beautiful and captivating wood duck is roughly 19-21 inches long, with a wingspan of 26-29 inches wide. It is roughly half the size of a mallard, but most of the comparisons stop there. Wood Ducks are cavity nesters and prefer breeding habitat that includes deciduous trees. They are uniquely equipped to fly through a tangle of branches to reach their nest site in a tree cavity. They have the largest eye of any duck, a broad wing for maneuvering, aided by a tail that is long and wide. Their legs are near the center of their body making them agile on the ground when searching for acorns on a forest floor. Woodies are classified as perching ducks; highly developed toes and claws allow them to grasp and perch on tree branches. Their ability to perch on limbs and love of woodland swamps may be where they acquired the name "wood duck."
