Going Out
By Ed Wesely
A
mystery spider. There are more than 200 species of
wolf spiders in North America, so the small one I found on
a snowmobile trail last Friday was, to me, “just a wolf spider.”
I hadn’t a clue about its species—like sighting a sparrow, but
without knowing if it’s a “song” or “chipping” sparrow.
The little fellow was about half-an-inch long, and appeared
to be frozen onto the snow. But that wasn’t the case. When I touched
it with a twig the wolf spider moved slightly and tried to crawl. A zip-lock
bag with scraps for the chickens was still in my coat pocket, and proved
to be a decent shelter for the spider.
Still surprised that it had the resilience to survive
a frigid day on the surface of the snow, I carried it to the house and
consulted a “Golden Guide” entitled “Spiders and Their Kin.” (The “Golden”
paperback field guides are a miracle of publishing. Pocket sized, full
of pictures, and covering several dozen natural history topics, they’re
still a bargain at $5.95 each).
During warm months, the odds are that solitary spiders
in garden furrows or running across the grass are wolf spiders. Even
so, because they pursue and trap insects without spinning webs, they
don’t advertise themselves. No silken webs or funnels mark their territories.
“At rest they stay under stones,” relates my Golden Guide.
“Some dig short tunnels, others deep burrows… They have good vision and
a highly developed sense of touch.”
But what brought my little captive to the surface of the
snow on a frigid January day? And how did it get there? And what adaptation
kept it stirring?
I don’t have answers. But thanks to a paragraph from the
Golden Guide, I’m less astonished that the wolf spider wasn’t frozen
stiff: “Some species are widespread over the Northern Hemisphere… They
make up a large proportion of the spider population in the Arctic and
on high mountains.”
Reassured by that information, I hiked through the snow
a day later and deposited my now active spider in leaf-litter at the
base of a giant maple tree—among knotted, south facing roots that are
frequently 10 degrees warmer than the air temperature.
Bald
eagle survey. On January 7, the New York Department
of Environmental Conservation (DEC) made a helicopter survey
of eagles wintering on the Upper Hudson and Delaware Rivers—during
the one brilliant, sunny day we’d had in early January!
Along a route that included the Hudson River, from Troy
to Croton Point, NY, and the Delaware from Port Jervis to Hancock, a
DEC team counted 234 eagles. They also received radio signals “from five
previously tagged eagles.” My RiverTalk column
has additional details.
Narrowsburg Eaglefest. Don’t forget that Saturday, January 18, is
the date of Narrowsburg’s Eaglefest. Families
should note that the day is “child friendly,” and that the program will
begin at 10:00 a.m. in the school auditorium. For further information
