The Canada goose may evoke mixed emotions among many Iowans.
To the golf course greenskeeper, gaggles of these geese may result in a painstaking effort to keep them from covering everything in stinky feces.
The seasoned birdwatcher may know the goose’s taxonomy underwent an extensive overhaul in 2004. Up until the end of the 20th century, the Canada goose was recognized as a group of around a dozen subspecies. I recently argued with a hunter on social media about what a Canada versus cackling goose was. The hunter said the cackling goose also was a Canada goose, merely a derivative.
Then I realized we were simply having a quibbling over semantics. Hunters don’t prescribe to taxonomy for a logical reason.
Before the establishment of cackling goose, the Canada goose was divided into three main categories — large, medium and small geese. All have the same generalized coloration: a large black neck with a white cheek patch and a body varying in the amount of brown. All have a white undertail with black legs and feet. By the end of the 1980s, authorities were starting to identify the smaller geese as a distinct species, the cackling goose. Four different races of cackling geese are now recognized.
Iowa has Richardson’s race of cackling.
Canada geese range in size from the largest, the Giant Canada goose, to the smallest, the Lesser Canada goose. The lesser is somewhat larger than the cackling goose. What sets the cackling apart from the lesser Canada is predominantly head shape. Cackling geese tend to have an angular forehead, which is more sloped on a lesser. Cackling also have a smaller, stubbier bill. While lesser Canada geese have a smaller bill than the larger races, the bill is generally longer when compared to cackling. Also notable, cackling geese have a body size approaching that of a mallard.
Canada geese numbers have increased dramatically over the last half century. Golf courses and large park lawns offer them food throughout the year, thus there is relatively little need to migrate. In Iowa, Canada geese may migrate within the state’s borders.
Although more than 2.5 million geese are taken annually by hunters, their population does not seem to be affected. Known as “dark geese,” hunters lump Canada, greater white-fronted and cackling together. Just imagine how confusing it would be for the Iowa DNR to divide all the dark geese into categories with set limits. These dark geese can be tough enough to identify just watching them in binoculars or a spotting scope for a prolonged period.
Birders and hunters can lay the semantics to rest.
OTHER BIRDS IN MARCH

— Snow geese, including both light and dark morphs, along with Ross’s goose and greater white-fronted geese can be found both with or separate from flocks of Canada and cackling. There are currently hundreds of thousands of snow geese farther south in Missouri and Illinois. Get ready to start seeing huge pushes of geese into Eastern Iowa.
— Snow buntings are irrupting into central and Eastern Iowa due to the severity of the snow situation to the north and west. Early March will be a great opportunity to see them in sizable flocks around Cedar Rapids. Be prepared to scour the country roads in order to find them.
— Great horned and barred owl should be nesting, so keep your eyes peeled at large trees with ample cavities and platforms. Bald eagles and especially red-tailed hawks should be more commonly seen in pairs as nesting proceeds.
