Branta canadensis
When most North Americans imagine the sight and sound of a wild goose, it is the Canada Goose that comes immediately to mind, with good reason: this species is the most numerous and the most visible large waterfowl on the continent. The situation is no different in the Rockies. Although Canada Geese are not as abundant here as elsewhere in North America, they are the only geese to nest in the mountains; with persistence, you can find a pair nesting alongside a marsh or even near a golf course. Although the sight of one of these wetland giants can become quite mundane by the end of summer, the early spring sight of a flock breaking the horizon preludes the excitement of the upcoming season. |
