Wing Shape

The shape of a bird's wing is often an indication of its habits and behavior. Fast flying birds have long, pointed wings. Soaring birds have long, broad wings. Different songbirds will have a slightly different wing shape. Some species look so much alike (Empidonax flycatchers) that scientists sometimes use the length of specific feathers to confirm a species' identification.

Fun Facts

Buffleheads are small enough to use old Northern Flicker cavities, something the larger goldeneyes are unable to do.

Female Buffleheads sometimes lay eggs in other females’ nests, particularly if few cavities are available.

Vocalizations

Buffleheads are generally silent.

Nesting

The Bufflehead’s nest is within a tree cavity or in a nest box.

Number: Usually lay 8-10 eggs.

Color: Pale buff in color.

Incubation and fledging:

The young hatch at about 29-31 days and leave the nest within a day or two after hatching, but are not fledged for about 8-9 weeks.
