1) Canada Geese live year-round in Colorado, according to Colorado Parks & Wildlife. While many geese migrate, such as the flock I encountered, quite a few Canada Geese reside permanently in our state.
2) The correct name is Canada Geese, not Canadian, according to National Geographic.
3) The next time I walked, the geese were gone. They left behind large piles of droppings. According to the aforementioned National Geographic article, "Just 50 geese can produce two and a half tons of excrement in a year."
4) Both sources stated that the geese had been endangered at one point in history, but that the Canada Goose was a wildlife protection program success story. So much so that they can present a nuisance in urban areas and airports, and can damage crops.
5) On an excursion with the grandkids to a local nature center this weekend, I learned that my teenage granddaughter's arms from fingertip to fingertip are the same breadth as that of the wing span of the Canada Goose.
