Project
Feederwatch
(This 816th Buffalo

I
continue to be impressed by the outreach activities of the Laboratory of
Ornithology at Cornell University. The Lab is an organization of professionals,
some of them enjoying university professorial appointments, but many of their
activities involve people they so aptly term citizen scientists, amateurs who
contribute observational data. The voluminous information so acquired is
analyzed to provide temporal and geographic comparisons and analyses of bird
populations that are then made available to the public. Most of this data
acquisition is managed by computer, thus the results may be accessed
instantaneously.
Among
the many Lab projects are the field trip reports gathered on eBird, the cavity
nesting bird surveys of the Birdhouse Network, the annual four day (next year
February 16-19) national survey of winter birds called the Great Backyard Bird
Count, and the nesting habitat studies of the Birds in Forested Landscapes
program.
Today
I focus on the Lab's Project Feederwatch, a timely topic for this time of year
when many readers are stocking their bird feeders to serve this year's winter
visitors.
Project FeederWatch is an outgrowth of an activity begun at
Ontario, Canadašs Long Point Bird Observatory. Dr. Erica Dunn established the
Ontario Feeder Bird survey there in 1976. More than 500 observers participated
in that program over the following ten years.
At the end of that period, however, the Long Point team decided
that a continental survey would more accurately monitor the large-scale
movements of winter birds. They contacted the Cornell Lab, and the project was
taken over by Lab staff, drawing heavily on the experience and expertise of the
Long Point group but extending participation to thousands of birders already
associated with the Lab across North America.
During that first year, more than 4000 people enrolled.
FeederWatchers represented every mainland state in the U.S. and most provinces
in Canada. Now the number of observers involved in the project has grown to
more than 15,000. Today, Project FeederWatch is a cooperative research activity
of the Cornell Lab of Ornithology, Bird Studies Canada (formerly the Long Point
Bird Observatory), the National Audubon Society, and the Canadian Nature
Federation. It is now a proven tool for monitoring the distribution and
abundance of winter bird populations.
Participation
in Project Feederwatch is open but there is a small fee of $15 ($12 to Lab
members). You can sign up through the
project website or by mail to Project Feederwatch, Cornell Lab of Ornithology,
P.O. Box 11, Ithaca NY 14851-0011. The fees pay for maintenance
of the web site, managing the database, data analysis, interaction with
participants, printing and shipping project materials, and dissemination of the
information learned from the data. They also help cover the cost of publishing
two newsletters for project participants: BirdScope for U.S. participants and
BirdWatch Canada for Canadians.
Contributing is easy and can be done by computer or by mail. You
identify and describe your site, identify and count birds visiting your feeders
on pairs of days, and submit your data on the forms the Lab provides. Although
those who have many bird visitors have the most fun, even those who record few
birds contribute to our knowledge.
According to Lab staff, here are some things the survey provides:
long-term trends in bird distribution and abundance; the timing and extent of
winter irruptions of winter finches and other species; expansions or
contractions in the winter ranges of feeder birds; the kinds of foods and
environmental factors that attract birds; and how disease is spread among birds
that visit feeders.
Consider
one example of the evidence that the data contributes. Many birders feel that
increasing numbers of birds remain in our area through the winter. The
observations of individual birders are limited, however, and tend to focus on
less common species. The systematic data of Project Feederwatch respond better
to this kind of question.
Two
final comments about bird feeding: First, clean your feeders regularly to avoid spreading avian diseases. Once a month, apply a
solution of one part bleach, ten parts water. Allow the mixture to set on the
feeders for ten minutes, then drain, rinse and dry before refilling.
Second, obey local rat restrictions on bird feeding. While you may
consider these laws draconian, they contribute to control of a significant
problem.-- Gerry Rising
