I was recently asked, "do hummingbirds molt?’ Yes, they indeed do. It is my hope that the information below will help inform you on this subject.
By the time fall migration comes, many hummingbirds are relying on worn-out feathers. They will begin to molt anytime from September to November, while out of view of most U.S. and Canada hummingbird watchers. Each feather will take several weeks to regain its size and shape.
