The 2006 Great
Backyard Bird Count
(This 776th Buffalo Sunday News
column was first published on February 12, 2006.)
The participation
of non-professionals in scientific activities has become so widespread that it
now has its own designation. It is called citizen science.
One of the best
opportunities to join this activity occurs this weekend when the Cornell
Laboratory of Ornithology Great Backyard Bird Count (GBBC) is held in the
United States and Canada.
The
count period runs from Friday, February 17 through Monday, February 20 and
participants can count on any one or all of those days. To participate, tabulate
the highest number of each bird species you see at one time (to insure that
birds are not counted more than once) and keep track of the time spent
counting. Then log onto the Cornell Lab's BirdSource website
www.birdsource.org/gbbc, click on "Submit Your Bird Checklist" and
follow the simple instructions to file your report. Readers who are not
computer savvy may consider this a serious hurdle, but remember that your local
library has computer stations and friendly librarians to help you with this quite
straightforward procedure.
Although
the word "Backyard" is included in the title of the count, the
instructions say, "Count the birds in your
backyard, local park, or other natural area on one or all four count days. You
can count in as many different locations as you wish, just make sure to keep
separate records and fill out a checklist for each area."
This will be the
eighth count year. Last year over 52,000 checklists were submitted, an
indication of both the popularity and the continued growth of the avocation of
bird watching.
As an old fogy
who has been around since before the computer revolution, I find myself
astonished by the immediate feedback the GBBC website provides. Submitted
checklists are processed immediately and you can get information about totals
for North America, for the Great Lakes Region and for New York, as well as maps
for individual species.
My favorite way
to use the maps is to pick a species of interest to me, say evening grosbeak;
then a region, either Great Lakes or North America; and finally
"Multi-year Animation." I'm interested in evening grosbeaks, those
large goldfinch look-alikes that gobble sunflower seeds by the pound, because
they have been absent from Buffalo feeders for several years.
The animation
agrees with my experience. The evening grosbeak has indeed been away from
Buffalo since 2000 (the period covered by the animation) but a few did occur in
the Southern Tier in 2000, 2002 and 2004.
The amount of
information on the website is overwhelming and some is quite unexpected. I
would never have guessed the species with the greatest numbers in North America
last year. My guess, Canada goose, would have been close -- it was second with
688,715 reported. But 835,369 snow geese made first.
Local birders are
fortunate to see a few snow geese each year, but they have become so common on
their breeding grounds around Hudson and James Bay that they are destroying
habitat. The US Fish and Wildlife Service tells us: "The Mid-continent population of lesser snow geese has
tripled to nearly 6 million in the past 30 years. As a consequence of their
numbers and their destructive feeding habits, large tracts of coastal wetlands
are being degraded, consumption that adversely impacts most of the species
sharing this coastal habitat." Those birds migrate mostly to our western
states.
Although we don't
see many, snow goose numbers are already increasing in central New York.
Thousands are recorded during migrations in Montezuma National Wildlife Refuge
and the Finger Lakes each year. They are beautiful birds, their lovely white
bodies with black wing tips marred only by an ugly grin mark on their bills,
and we'll soon be seeing more. We can only hope, however, that their population
doesn't grow out of control as have Canada geese.
Those two goose
species topped the totals list, but the cardinal headed the list of birds most
often reported on national lists. In New York it was beaten out by the
black-capped chickadee and was only slightly ahead of the downy woodpecker.
I urge readers to
participate in this national census. It is a great way to beat cabin
fever.-- Gerry Rising
