Both the Sun and
the Moon vanish from the sky this February
By Fred Schaaf
If you're getting just plain
sick of winter, perhaps some fine February and March birds
and eclipses can help brighten things up a bit. By making
the heavens, birds, and nature in general an important part
of your life, you'll be following in the footsteps of a
number of the men whose lives we are supposed to
collectively celebrate each February on Presidents' Day.
Snowbirds
February is often the snowiest month in many parts of the
U.S. The swallows may still be many weeks away from
returning; what birds can we look for to cheer us up? There
may be chickadees, titmice, nuthatches, and of course
brilliant cardinals and blue jays at our feeders. But there
are two other kinds of birds which may bolster us against
wintry weather partly by virtue of their own incredible
hardiness in the face of cold and snow. I'm referring to the
"snowbirds": juncoes and snow buntings.
The juncoes are much
more common across the U.S. The most widespread species of
them was, until a few decades ago, called the slate-colored
junco. Then a decision was made that slate-colored juncoes
and the Oregon junco should really be considered variants of
the same species, the dark-eyed junco. The slate-colored
junco seems rather drab in its plumage: gray head and back
(darker gray in males), white underneath. Thoreau described
them as "leaden skies above, snow below." But there is one
wonderfully distinguishing Surprise when a junco flies off:
the feathers on either edge of the tail flash white. Juncoes
also have pinkish beaks but this is generally a pale color
and not immediately noticed.
Juncoes spend the winter across
most of the U.S. north of Georgia. It's easy to attract
flocks of them, but they are almost always
ground-feeders—even their nests are hidden on or near
the ground—so leave food for them beneath your feeder.
In New Jersey where I live, they spend almost exactly six
months, typically arriving from the north in mid-October and
leaving for the north in mid-April. Along the Appalachians
and across New England, some juncoes are year-long residents.

Most, however, summer in Canada's far north as the southern
part of Hudson Bay in the east but as far north as the
shores of the Arctic Ocean in western Canada and Alaska.
Many of our warblers and other songbirds that arrive in
spring are inherently tropical or sub-tropical birds and
they look it, with their bright colors. But we should be
equally impressed that the juncoes are natives of the
subArctic and Arctic who come visit us in the U.S. to enjoy
our "mild" weather in winter!
