There is a very good book on American waterfowl titled The Ducks, Geese and
Swans of North America. By Francis H Kortright, illustrated by T.M. Short.
Copyright December 1942.
There are 4 plates in the book that illustrate the downy young of most
species.
The photos of the young bird on Hood are a very good match for the
illustration in this book.
