Treasure From the Winter Woods Among the treasures to be collected from the winter woods
are pine conesthe reproductive structures of an ancient genus
that preceded flowering plants by 50 million years and whose Devonian
age contemporaries are now coal. The cones you'll want to pick up are
the larger, seed-bearing females. Hard pinessuch as red, lodgepole,
shortleaf, longleaf, slash, ponderosa, pitch, and loblollygenerally
produce woody, thick-scaled cones armored with prickers. Soft pinessuch
as eastern white, western white, sugar pine, whitebark, limber, foxtail,
bristlecone, and pinyonproduce softer, smoother, more elongated
cones. Even when dry and seedless, the female cones of sugar pines can
measure nearly two feet and weigh a pound. Ripe cones of hard pines
make superb bird feeders. Fill all nooks with peanut butter, then roll
the cones in birdseed. Ripe cones of soft pines are best for fire starters.
Soak them in melted paraffin or candle wax. For red flames, pre-soak
cones in strontium chloride, then dry; for purple, use potassium chloride;
for green, copper sulfate; for orange, calcium chloride (all available
at chemical supply houses). For yellow flames, use salty water; for
white, Epsom salts. You'll start to hear it throughout most of our nation as the sun pushes
higher into the winter skya clear, ringing caroling that comes
before almost any other sign of springmaybe a whistled purdy,
purdy, purdy or a cheer, cheer, cheer or a whit-chew,
whit-chew, whit-chew. It's the song of the northern cardinal, another
adaptive species that is thriving and extending its range. It's not
just the male you're hearing; the female counters his notes with loud
caroling of her own, eliciting matching notes from her prospective mate.
As courtship continues into late winter, the male will bring the female
food, tilting his head to place it in her beak. In response, she'll
flutter her wings in fledglinglike excitement. To attract cardinals,
put out black sunflower seed and cracked corn. They'll come to feeders
but prefer to forage on the ground. For most any American, save residents of the Southwest
and far and central West, finding painted turtles basking in the July
sun entails no more than a stroll to the nearest wetlands. But finding
them under or on the ice is a challenge and, therefore, good fun. Not
only are painted turtles the most widely distributed aquatic reptiles
in the United States and Canada, they are the most tolerant of cold.
When pond ice is clear, look for them resting on or moving slowly across
the bottom. On warm days in late winter, you may encounter them basking
on the edge of retreating ice. Freshwater turtles are able to hibernate
underwater by absorbing oxygen through their skin, but only the painted
turtle can survive a winter in water that has been deoxygenated by decaying
plant matter. It accomplishes this by anaerobic respiration. Because
this strategy produces lactic acid, which disrupts blood chemistry,
the painted turtle must break down the acid by releasing carbonate from
its shell and bonesbasically, consuming its own skeleton. The
next time you see one of these strikingly beautiful turtles, pause for
an instant and celebrate nature's resiliency, and rejoice in the fact
that there is lots of wildlife that isn't disappearing. Winter, when breeding increases coyotes' activity and their passage
is recorded in fresh snow, is a fine time to snoop into their private
lives. Coyotes leave straighter trails than dogs, and their prints are
less splayed. If you've seen tracks, or even if you haven't, stand at
night on the edge of a meadow or lake or anyplace your voice will carry,
and howl. You don't have to get it anywhere near right; the coyotes
probably know you're a fake, but often they can't stand not to comment.
Soon you'll be left out of the conversation. In the face of intense
human persecution, and perhaps because of it, coyotes have extended
their range from the western plains to the rest of the continental United
States. Coyotes are larger and more wolflike in the East, where they
were first noticed in the early 20th century. They may have hybridized
with wolves on their way from the West, or they may have been present
all along, mistaken for small wolves by early settlers. A coyote will
frequently hunt with a badger, apparently showing it where to dig out
burrowing prey that the two will share. Although a badger will sourly
reject a coyote's invitations to romp, when the badger approaches a
coyote, the coyote will wag its tail and roll on its back in delight.
A badger will allow a coyote to rest beside it and even touch it. The
partnership is no anomaly; in fact, when some coyote researchers see
a badger in spring or early summer, they instinctively look for its
coyote companion. When autumn dies, so do the beautiful black-and-yellow
orb weavers whose dew-spangled webs stretched across garden paths and
meadow grass just about everywhere in the contiguous 48 states. But
during winter young garden spiders hatch in sacks that may contain as
many as 1,400 eggs. They molt inside, then emerge in spring, crawling
off or flying away on silk parachutes thrown to the wind. Look for the
pear-shaped, inch-long paperlike sacks hanging from tall weed and grass
stems, especially in locations where you've seen webs. As the days dwindle down, the fur of the snowshoe hare goes white,
but unlike the pelage of other mammalsincluding, alas, usit
will become brown again in spring. If a hare goes white before the snow
falls, it's in big trouble, because amid bare hardwoods or black conifers
it stands out like phosphorus in a night sea. The snowshoe part
of its name derives from large, splayed hind feet that allow it to travel
easily over snow. Throughout its rangefrom Alaska, across most
of Canada and our northern states, and down the spines of the Rockies
and the Allegheniesfew prey species are more abundant or subject
to wilder population swings. In good hare years predators such as owls,
foxes, fishers, and lynx thrive. But as hares proliferate, they deplete
their bark-and-twig food supplies, triggering a population crash that
soon extends to their major predators.
