Wood ducks nest in tree cavities sometimes several feet high above the ground and readily use artificial nest boxes. At the turn of the century, over hunting for its plumage and habitat loss forced it to the verge of extinction. Today the population is stable and they are very common in captivity. The Tennessee Aquarium has a pair in the Delta Country exhibit.
