Fun Facts In the early 1900s, wood ducks were nearly wiped out because of unrestricted year-round market hunting and habitat destruction. Hunting was severally restricted by the passing of the Migratory Bird Treaty Act of 1918, and not relaxed until 1941. Recovery of wood ducks is now heralded as one of the great wildlife conservation success stories of the 20th century, due in part to construction and distribution of nesting boxes.
