Geese, ducks, and swans are flocking to the Yukon-Kuskokwim Delta to nest and raise their young. To allow the birds time to lay their eggs, waterfowl hunting will close for the following month. The shutdown begins May 28, 2019 and lasts through June 28, 2019. For black brant geese, the closure will extend through July 10, 2019 to give the young birds time to fledge, or grow feathers strong enough to fly.
