We have added another bird, the Hooded Merganser, to the Park List,
this summer. This interesting little "saw-bill" was recorded at Lake
James on August 16.
Hooded Mergansers, like the Wood Duck, are inhabitants of the streams
and mountain lakes, and the former is often confused with the Wood Duck
in identity. The bright handsome plumage of the drake, black, white and
chestnut, creates a rivalry in dress, that only the Wood Duck can
surpass.
Hooded Mergansers do not migrate but stay with us all winter,
frequenting the larger lakes and rivers and occasionally paying a visit
to salt water tide-flats. Beside small fish, their diet consists of much
vegetable matter, growing below the water's surface which they obtain by
diving. In this way, the flesh of this Merganser has often a delicious
game flavor and need not be classed with their larger cousins, the
American or the Red-breasted Mergansers, as unfit for food on account of
a fishy flavor.
"Hoodies", like Wood Ducks, choose a hole in a tree or snag for a
nesting site. It is an amazing feat to the watching ornithologist to see
this bird approach the hole at full speed and seemingly without
hesitation in flight, enter the nesting cavity. The eggs, usually seven
to eleven, are of an ivory white color, very round in shape and have the
hardest shell of any of our North American bird's eggs. Ask the
oologist, he knows, when he had to drill holes in them!
One spring day a few years ago, I noticed a pair of these ducks
circling a pond. The female flew to a hole in a dead snag, the male
alighting on the water below; an interesting investigation for the
future. At the proper time (April 27) a visit was made and a few downy
feathers sticking to the rough bark assured an occupied nest. Climbing
up, I was more than surprised to find, that after laying four eggs, the
bird had evidently been driven off by a Wood Duck who had completed the
clutch by adding nine of her own eggs. This was too good a prize for the
oologist to leave, but a later visit disclosed a new clutch of thirteen
eggs, all Wood Duck this time, so she was relieved of all aquatic
scandal or future foster-parentage.
