Of the geese found in the region, the well-known Canada goose is nearly ubiquitous. That’s not always been the case. For instance, in his book “The Birds of Northeast Tennessee,” Rick Knight points out that the geese now present throughout the year resulted from stocking programs conducted in the 1970s and 1980s. In earlier decades, the Canada goose was considered a rare winter visitor to the region.
Seeing the Canada goose in every sort of habitat from golf courses to grassy margins along city walking trails, it’s hard to imagine a time when this goose wasn’t one of the region’s most common waterfowl.
The world’s geese are not as numerous as ducks, but there are still about 20 species of geese worldwide, compared to about 120 species of ducks. While both ducks and geese are lumped together as waterfowl, most geese are more terrestrial than ducks. Birders are just as likely to spot geese in a pasture or on the greens of a golf course as they are on a lake or pond.
There have been several species of geese usually considered rare to uncommon in the region that have been spotted by birders thus far this winter season. I personally observed greater white-fronted geese at several different locations in November and December.
The greater white-fronted goose is considerably smaller than a Canada goose. The bird is named for the distinctive white band found at the base of its bill. This white band also helps distinguish this goose from similar domestic geese. The sexes are similar in appearance, but females are usually smaller than males. The head, neck and upper back of white-fronted geese are grayish-brown. The lower back and rump are dark brown, and the tail is dark brown and edged with white. The chest and breast are grayish with dark brown to black blotches and bars on the breast, giving this goose the nickname “specklebelly.” The bill is pinkish and the legs and feet are orange.
The greater white-fronted goose breeds in North America as well as in Europe and Asia, and they spend the winter throughout the United States and even in Japan. Most nesting in North America takes place on the North Slope of Alaska and across the western and central Canadian Arctic. Wintering habitats include coastal marshes, wet fields and and freshwater wetlands.
Only a couple of weeks ago, I spotted a snow goose at the fish pond located at Erwin Fishery Park. The snow goose is a North American goose known for its white plumage that gives the bird its common name; however, the snow goose actually comes in two versions: the white phase and a blue phase, which is often referred to as a “blue goose.”
The snow goose breeds in regions in the far north, including Alaska, Canada, Greenland and even the northeastern tip of Siberia. They may spend the winter as far south as Texas and Mexico, although some will migrate no farther than southwestern British Columbia in Canada.
The snow goose bucks the trends that show many species of waterfowl declining. Recent surveys show that the population of the snow goose exceeds five million birds, which is an increase of more than 300 percent since the mid-1970s. In fact, this goose is thriving to such a degree that the large population has begun to inflict damage on its breeding habitat in some tundra regions.
A smaller relative to the snow goose is the Ross’s goose, which for all practical purposes looks like a snow goose in miniature. The common name of this goose honors Bernard R. Ross, who was associated with the Hudson’s Bay Company in Canada’s Northwest Territories.
Here’s a quick history lesson. Hudson’s Bay Company is the oldest commercial corporation in North America. The company has been in continuous operation for more than 340 years, which ranks it as one of the oldest in the world. The company began as a fur-trading enterprise, thanks to an English royal charter back in 1670 during the reign of King Charles II. These days, Hudson’s Bay Company owns and operates retail stores throughout Canada and the United States.
In addition to his trade in furs, Ross collected specimens for the Smithsonian Institution in Washington, D.C. Ross is responsible for giving the goose that now bears his name one of its early common names – the Horned Wavy Goose of Hearne. I wonder why that never caught on?
Ross repeatedly insisted that this small goose was a species distinct from the related and larger lesser snow goose and greater snow goose. His vouching for this small white goose eventually convinced other experts that this bird was indeed its own species.
Ross was born in Ireland in 1827. He died in Toronto, Ontario, in 1874. He was described by other prominent early naturalists as “enthusiastic” and “a careful observer” in the employ of Hudson’s Bay Company. When John Cassin gave the Ross’s Goose its first scientific name of Anser rossii in 1861, he paid tribute to the Hudson’s Bay Company’s Ross.
The Ross’s goose has a “cuteness” factor working in its favor. For a goose, it is rather small. It could best be described as a snow goose in miniature. In fact, it isn’t much larger than such ducks as mallards and is considered the smallest of North America’s geese.
The Ross’s goose has also acquired some other common names, including “galoot” and “scabby-nosed wavey.” This latter name was inspired by the bird’s bill, which is covered with rough bumps around the base. I have to admit that “scabby-nosed wavey” is a name likely to stick in the memory. Today, the Ross’s goose’s scientific name is Chen rossii.
Other geese found worldwide include the pink-footed goose, bar-headed goose, emperor goose, red-breasted goose and barnacle goose.
So, does this inspire you to try a wild goose chase of your own? If it does, best of luck in your efforts.
