Earlier this week, I went exploring William L. Finley National Wildlife Refuge south of Corvallis, OR. The refuge was established to protect the wintering grounds of the dusky Canada Goose, a subspecies of Canada Goose that spend winter here and breed in Alaska. I’d never even heard of these geese until I visited the refuge. Much of the refuge is closed over winter to protect their habitat, but there’s still plenty of birds to see at the spaces that are open.
The difference between dusky Canada Geese and others was not immediately clear to me, but after checking some references, I can say with confidence that these are dusky Canada Geese. They have a darker, almost brown breast.
And I can see why the refuge is here because the geese love it. While I walked to one of the marsh overlooks, a sudden roar of goose honks sounded in the distance. I looked up to see a hundreds of geese flying noisily overhead and I thought, now that is a gaggle of geese! Further along, some of the fields were painted brown with huge numbers of geese, more than I’ve ever seen before!
Dusky Canada Geese were once the only population of over-wintering geese in the Wilamette Valley, but in the last fiftty years, Cackling Geese have moved in as well as a new resident group of Canada Geese. Perhaps this is yet another sign of the times in an ever-warming climate with other populations of birds like Anna’s Hummingbird and Red-shouldered Hawks creeping north and staying over the winter, too. Sometimes I think animals and people living closely to nature can tell us a whole lot about the status of our ecosystems if we just learned to pay attention.
