Think Green Thursday

Rambling Woods hosts this thoughtful, environmentally-sensitive meme.

Canada geese are protected by the United States Fish and
Wildlife Service under the Migratory Bird Treaty Act of 1918 and
the Migratory Bird Conservation Act of 1929. The former, the
implementation of a 1916 convention signed by the United States and
Canada, prohibits the hunting, possessing, purchasing and exporting
of migratory birds "or any part, or egg of any such bird."

However, the Secretary of the Interior is also authorized to
legalize temporary hunting of migratory birds "based on due regard
to distribution, abundance, and breeding habits." States may
implement additional laws that are tougher in enforcement.
Violations of this act constitute federal felonies and are subject
to fines and imprisonment. The Migratory Bird Conservation Act
authorizes the funding and maintenance of wild migratory bird

The controversy over Canada geese concerns whether or not they
are, in fact, migratory and hence privy to federal protection.
Canada geese--as their name implies--until recent years regularly
migrated to northern Canada for the summer. But over the last 20-
25 years, many geese have chosen to remain south of the border, and
the populations of these non-migratory geese have grown into the
millions, with geese situated in eastern states from Maine down to
Virginia. Aerial observations of some flocks have led to the
conclusion the number of geese has doubled since 1975 and will
continue to grow if present trends continue.

Why have the geese lost their biological impulse to migrate?
Besides protection from game-hunters, the geese have been
encouraged by the spread of suburban developments, corporate parks
and recreational areas. Canada geese prefer the short-cut,
manicured grass found on golf courses and on the properties of
suburban corporate headquarters over the wild tundra of Canada.
The shorter grasses, besides providing a plentiful source of food,
afford the geese security--they can better monitor predators with
the clearer views. Furthermore, the pools and ponds that normally
accompany these developments are perfect sources of still drinking
water. In a short time, then, the geese have learned that the
environment created by humans was much closer to goose paradise
than they would experience in Canada, and chose to stay.
While the complacency of these beautiful birds may be a
godsend to naturalists, they have been a nightmare for farmers,
recreation service providers, and tourists. Geese often invade
local farms to eat corn and other grain crops, leaving farmers with
substantially less for harvest. The construction of dams in the
1950's and 1960's has created more area for standing water, and
irrigation ditches lead the geese straight to the fields. The
geese also compete with sheep and other livestock for grazing land.
In the end, farmers have to spend considerably more on fertilizer,
feedstuffs and geese prevention measures.

A sector of the economy that has been particularly effected by
non-migratory Canada geese is golf. Golf courses are perfect
habitats for Canada geese, with plenty of rich, short grass and
ponds. Course managers have to spend thousands of dollars annually
to repair greens and fairways and to clean up goose dropping for
the convenience of their members. Parks and recreational lakes and
ponds face similar damage costs, as did the Aqueduct Racetrack in
New York state, where hundreds of geese had taken up residence on
the infield, refusing to leave until they had substantially ravaged
the turf.

A more serious threat posed by the thriving Canada goose
population is interference with ground and air travel.Goose and
gosling crossings on major roads can create back-ups and fender-
benders, as many drivers swerve or stop suddenly to hitting them.
Canada geese have been particularly problematic for airliners,
because a goose sucked into an engine can cause considerable damage
and put crew and passenger lives at risk. Finally, the Canada
geese's droppings pose various health and physical hazards to
humans. Goose manure is very slick and can contribute to broken
ankles and other serious injuries if stepped on. But it also
breeds the bacterium E. Coli, which promotes flulike symptoms in

The Canada geese have so adapted to their new sedentary
existences, they have learned to ignore the various means employed
to shoo them away. Apparently, these geese will barely ruffle a
feather when shots are fired or when scarecrows and flags are
displayed in their view. The frustration of the several business
interests noted above has gotten to the point where the U.S. Fish
and Wildlife Service and its state counterparts have given in and
sanctioned limited hunting seasons on Canada geese. These hunts
are justified as population-thinning measures on a species that has
temporarily transcended its "endangered" status. Thousands of
geese have been killed in these hunts, with bag limits ranging from
3 to 5 geese per day per hunter over a 10-day season.

The Department of the Interior has also sanctioned the limited
sterilization of Canada goose eggs (done by shaking or puncturing
the eggshell). But appeals to remove the Canada goose from the
list of protected species have been denied. Persons who kill
Canada geese without permission are still charged as felons; such
is what happened to employees of a Williamsburg, Virginia golf
course, who killed 39 geese with poisoned birdseed and were fined
several thousands of dollars.

The hunts have predictably drawn criticism from bird-lovers,
who believe that the costs to agriculture, recreation and other
trades do not warrant such extreme measures. Thus new methods have
been experimented with to simply chase the geese away from private
and commercial areas. For instance, some people have invested in
grape Kool-Aid powder to sprinkle on lawns; the geese have a
digestive aversion to methyl anthranilate, a natural compound found in
grapes that causing a burning sensation in their
stomachs. Border collies have also been employed to shepherd
Canada geese on public spaces onto trailers for transport to
wildlife refuges.

All this leads me to believe that a lot more thought must
be given too figuring out humane ways to control the Canadian
geese population here in the U.S.

The geese certainly are a serious problem to many and must cost some people a fortune. I hate the thought of hunting any animal, but I can understand why some want to see it happen, when it endangers their livelihood. Quite a problem!

I've done a lot of research into the goose problem after some home owner here decided to shoot them leaving them to die on our pond and their goslings with no parents.

The biggest problem with Canada geese is that we've taken their natural habitat while then providing them with pseudo-habitat. IE green lawns. The lawns by the way are a poor alternative to the natural sedges and things they should be eating. The geese have to eat a huge amount to get any nutrition out of it most of them losing weight until they then look for crops to eat that have carbs like corn to bulk up for the winter.

The so-called resident geese are non-migratory, but many birds don't really migrate except for food and are protected. The geese that were involved in the jet liner coming down in NY were tested and found to be of the migratory geese, not the resident geese.

There are measures that can be employed to dissuade geese from nesting and eggs can be oiled or addled with a permit. We use a short fence along the property and that keeps the geese from our lawn.

The idea of rounding up families of screaming geese during their flightless period in June and gassing them with huge trucks is troublesome to me and doesn't make a dent in the population.

There is an organization called "Geese Peace" that has suggestions for humanly addressing the problems of Canada geese and no one should be feeding them bread or anything as it will cause them to stay around.

Sorry..guess I am still disturbed by taking those dead and dying geese out of our pond....Michelle

I detest Canada geese. We have a man-made lake in our community, and they love to hang around the paths and crap all over them. Yuck.
