Unable to excavate their own cavities, Goldeneye ducks are in constant search for good nesting sites. With a larger entrance hole than the Wood Duck Bird House, this box comes with wood chips and a ladder to provide an ideal place for them to lay their eggs. RANGE: Breeds in Alaska and across Canada to Newfoundland and the Maritime Provinces, south to mountains in Montana and Great Lakes. Winters in much of U.S., wherever water is open; also in Eurasia. Measures approximately 24 1/4" h x 11" w x 13" d. Made in Maine from eastern white pine.
