There is so much to love about Buffleheads. First and foremost, they are almost exclusively monogamous – one of the few ducks that often keeps the same mate for several years. They are relatively tiny – our smallest “diving” duck. (Ducks are divided into “diving” and “dabbling” ducks, according to their method of feeding.) So small are they that these cavity-nesting birds can fit in and often choose Northern Flicker holes in which to raise their young. We typically only see them during their nocturnal spring and fall migration to and from their breeding grounds in the boreal forests of western Canada and Alaska, when they rest and refuel on ponds and lakes during the day. If you chance upon a pair when the sun is out, be sure to notice the striking purple and green iridescent head feathers of the male (on right).
