What can cruise at an altitude of 29,000 feet, is a beloved icon of the great outdoors, and yet can be the bane of lawn lovers? It’s the honking harbinger of advancing autumn and coming cold (and sometimes, bad alliteration), the Canada goose.
The familiar autumn voices of Canada geese overhead can at once evoke the melancholy of a passing summer and the anticipation of a bracing new season of color and activity. Kids return to school, hunters take to the woods, and farmers work past dusk and into darkness, all to the cacophonous cries and the heartbeat of wings of migrating geese.
Through the end of November and even beyond, waves of airborne athletes—hundreds of thousands in number—will pass through Northern New York enroute from northern breeding sites to their winter feeding grounds. Canada geese nest in northern Quebec, Ontario, Labrador and Newfoundland, and winter over in southern NY State, Pennsylvania and other regions more hospitable than their arctic nests.
Depending on how far north they travel, the migrants may cover nearly 1,000 miles, typically flying at about 3,000 feet up. On average, the Canada geese that wing by us this fall measure 30-40 inches long, with a wingspan of 50-70 inches, and weigh 8.5 pounds. The largest wild Canada goose ever recorded weighed 24 lbs. and had an 88-inch wingspan, a record among all goose species worldwide. No one claims to completely understand how geese navigate, but being able to sense the Earth’s magnetic field seems to be critical. Visual cues, star positioning and even smell may play a role as well.
Among the things that endear Canada geese to us is the fact that they mate for life. From the time they begin breeding at 2 or 3 years old until they succumb to old age 20 or 25 years later, these birds will remain loyal to their mates. Should one member of the pair die, the other usually selects a new partner.
According to the Cornell Ornithology Lab, there are 11 subspecies of Branta canadensis, the Canada goose, although some authorities only recognize seven. (All experts agree, however, that no Canada goose has ever owned a valid Canadian passport even though the species is mistakenly called the “Canadian goose” fairly often.) The finer points of subspecies squabbling aside, a more important distinction is the one between migrant and resident Canada geese.
While there’s evidence that geese no longer fly as far south as they once did due to a changing climate, the journey is still an impressive one. As far as anyone knows, Canada geese have been migrating between their arctic nurseries and temperate wintering grounds for millennia. In contrast, it appears that resident geese are a more recent phenomenon.
A small population of resident Canada geese was documented in New York State in the early 1900s. The New York State Department of Environmental Conservation (NYSDEC) says these were descended from captive birds released downstate by private landowners. As the original population grew and spread, NYSDEC released captive-bred geese in the Albany area in the 1950s and 60s, increasing the resident NYS geese population. NYSDEC reports we now have about 200,000 resident Canada geese in the state.
Unfortunately, geese—especially residents—have become pests in community parks and on golf courses and home lawns. Being vegetarians, they are happy to take advantage of all sorts of feed, including grass. Their droppings elicit complaints on aesthetic grounds, and because they may be a source of fecal coliform bacteria. And when geese pass overhead, there’s a whole new meaning to the phrase “duck, duck, goose.”
Also, male geese can sometimes be aggressive as they seek to protect their young. Balancing the public desire for wildlife in their environment with complaints about nuisances and potential health risks is a challenge for public officials.
No matter how much of a problem resident waterfowl may become, I will always thrill to the cries of migrating geese in autumn and spring. The poet Mary Oliver sums it up for me in her poem “Wild Geese:”
“Whoever you are, no matter how lonely,
the world offers itself to your imagination,
calls to you like the wild geese, harsh and exciting,
over and over announcing your place in the family of things.”

thank you for the further info. on these amazing creatures .,., on a recent paddle on a backwoods stream we found a goose sitting on its nest ‘BUILT ON TOP OF A BEAVER LODGE’ .,.,., we’ve also come upon the unfortunate nest full of eggs underwater, the result of new beaver activity. Honk You again ,.,.
I enjoyed taking a gander at your article.
In the early 70’s when I used to camp in Moose River with mom and dad and my brothers and sister I recall clearly many flocks of geese flying over day and night nonstop over that paradise. I just don’t see that amount of geese anymore.Am I incorrect on this awareness or is it true geese are lower in numbers since then? Has anybody paid attention to this?Has there been a study?
