"This is
perfect snake-catching weather", announces Chris Parent to
about 30 members of the Muskoka Field Naturalists. The partly sunny,
partly cloudy weather, explains Killbear Provincial Park's snake
biologist, is ideal for spotting the eastern massasauga rattlesnake.
A few nervous
looks are exchanged, but most of the group is excited about this
weekend excursion near Parry Sound to view the habitat of the elusive
rattlesnake.
Half the group
heads out in the park with Parent to look for snakes; the rest of
the group will go later in the day. Snakes can't hear, but the vibrations
of too many feet will send them slithering away.
Parent hands
out snake sticks to members of the group. The long metal poles with
hooked ends are ideal for parting vegetation as well as for scooping
up a snake. Parent, however, stresses that he will be the only one
catching snakes today.
Parent is just
completing a master's degree in biology at Carleton University and
has been studying the rattlesnakes at Killbear since 1994.
"This species
really is going extinct right before our eyes," says Parent.
The massasauga rattler is found in parts of Ontario and nine American
states. It is considered endangered in the United States and in
Canada it is listed as threatened, one step away from endangered.
Loss of habitat,
primarily through urbanization, is the main reason for the shrinking
population. Poachers are also a growing problem.
"The eastern
shore of Georgian Bay is the last best place to find the snakes,"
explains Parent. In Muskoka, the rattlers have been seen as far
east as Bala.
Parent says
the research on the park's snakes will help scientists understand
how the species survives and perhaps offer insights on how to preserve
the population.
So far this
year, Parent has personally handled about 230 snakes. When he or
his colleagues catch one, they take the snake to the lab, where
it is tagged, weighed and measured. When the same snakes are caught
in the future, Parent can identify them and use this information
to chart growth and longevity patterns.
He also takes
blood samples and uses DNA to establish paternity and also to identify
genetic differences between this snake population and others.
As the Field
Naturalists move slowly through the woods, poking bushes with their
snake sticks, Parent explains that the reptiles are easy to miss.
"If I had
a dime for every time someone walked a snake-stick-length from a
rattler, I could pay for my own research," he says.
When the group
reaches an area the snakes are known to frequent, Parent suggests
people fan out. "Just yell if you find one," he says.
"You bet
we will," someone responds quickly.
With Parent
along, the group is guaranteed to see a snake. That's because three
of the park's snakes have been fitted with radio transmitters, enabling
Parent to track and study them.
Parent assembles
an antenna and receiver, and in mere minutes the blips emitted by
the receiver have led him to Buttercup, who is coiled and barely
visible beneath a pine tree.
Well camouflaged
by her brown and black markings, Buttercup doesn't move a millimetre
while the group crowds around to catch a glimpse.
Parent points
out that Buttercup hardly typifies the image of the rattlesnake
depicted by Hollywood.
"It's just
a shy little animal that really doesn't want anything to do with
people," he says.
The group moves
on until Parent finds a place to release a snake he has caught the
night before. The Muskoka Field Naturalists have given it their
initials, MFN, to be pronounced Muffin.
Once MFN has
been let out of his pillow case, he sits on the rock for several
minutes, allowing group members to get some pictures. Having had
enough attention, he eventually slides away like mercury, emitting
an annoyed rattle in the process. The sound could easily be mistaken
for a forest insect.
Even the more
nervous members of the group are impressed by these encounters.
And for Gil Hunter of Gravenhurst, who has a special interest in
reptiles and amphibians, this trip is a real treat.
"So many
people-they hate snakes and they can't really till you why,"
he says. But they're not so scary, "once you get to study their
point of view in life."
After tracking
down Al, another transmitter-implanted snake and the father of Buttercup's
babies, Parent takes the group to an area where he knows many snakes
hibernate.
The snakes will
all be in hibernation by the end of October, and have already started
to move closer to their hibernation grounds, which they use every
year.
Group members
almost step on a baby rattler basking on the rock. Parent quickly
scoops it into a pillow case, and marks down the date and weather
conditions under which it was caught. The snake will be released
the next day after its visit to the lab.
The group spreads
out and minutes later, Parent hears a rattle. "Don't move,"
he calls out to Barbara Coates of Milford Bay. Parent has spotted
two snakes by her feet.
In the ensuing
excitement, Parent manages to scoop each snake into its own pillow
case while Coates escapes unscathed.
"After
nine years I still get an adrenalin rush," says Parent as he
knots the sack. Snake bites are rare at Killbear. In fact, no park
visitor has ever been bitten while Parent has worked there. Still,
he doesn't take any chances.
The group packs
up and gets ready to return to the staff house when Dinny Nimmo
of Bala calls out, "Oh, there's a big one."
A large rattler
is making its way across the rocks, but not before Parent has snagged
it and placed it in the last pillow case.
With four snakes
to study, Parent pronounces the morning a success. The extra eyes
and ears of the Field Naturalists, he says, have helped increase
his data of Killbear's snake population.
"They've
actively contributed to the research," says Parent.
