Here are some 2nd-year Cooper's Hawks (birds in their first adult plumage) with retained juvenile flight feathers (the pale brownish ones). Note the lack of any grayish color and the more distinct banding of the juvenile feathers.

Jerry, thanks for posting these kinds of images that show molt and explaining exactly what we are seeing! Aging raptors based on molt is something many us really want to grasp better and more readily.

Keep posts like this one coming!!
