For the Birds: The Snow Geese are Coming - 70,000 strong

The Snow Geese are Coming! The Snow Geese are Coming!

Snow Geese have begun returning to their wintering grounds in the Skagit Valley, mostly near Fir Island, after having completed their summer breeding on the Russian island of Wrangel. Snow Geese are a North American species, with both lesser (western), and Greater (eastern) subspecies, all of which breed in various parts of the Arctic Tundra. They will continue to arrive for a couple of months, and stay until about March,

The rich farmland in Skagit County supports approximately 70,000 to 90,000 Snow Geese in their large wintering and migration flocks. It’s a treat to see these white geese with black under-wing tips land in nearby farm fields.

A Snow Goose usually forms a life-long pair bond in its second year, and starts raising its annual three to five goslings in its third year. The females are highly philopatric, meaning that they return to their hatching grounds to breed their young. The babies leave the nest and start feeding themselves within hours of hatching, but stay under their parents’ protection for the next two to three years.

Snow Geese, being herbivores, forage by using their sharp beaks to pick up seeds and rip vegetation from the ground. They are very vocal and can be heard more than a mile away from where they are foraging.

Occasionally you will see what is called a Blue Goose, which is the dark morph of the Snow Goose (both names come from their plumage). Both phases of Snow Geese have a black edge along their bills-it almost looks like someone ran a black crayon between the upper and lower bills. Their legs and feet are rose-colored, but their legs and heads are often stained a rusty-brown from the minerals in the soil. Juveniles have duller legs and bill. Snow Geese often feed with other species of wintering geese, like the Greater White-fronted Goose.

Now that their numbers appear to be stable, Snow Geese, including the Blues, may be hunted between October 15 and January 29 in Washington State, so be aware of your surroundings if you go viewing where hunting is permitted.

The Skagit Valley is a major wintering site for Snow Geese, Trumpeter Swans, and Tundra Swans. It is well worth the trip to go see and hear the flocks. Just remember to pull off the much used rural roads, and respect property rights. Who knows, you might see another white bird—the Snowy Owl.

  1. Great photos and article, Christine!
    I could not pass up the opportunity to share how lucky those Skagit farmers are. Having all those Snow Geese on their lands, helps to fertilize the soil. Animals fertilize the soil, especially bird droppings with microbes needed to break down the old plant materials and minerals in the soil and thereby make them available to next spring's growing plants! More birds means expensive, oil-derived fetilizing products need not be applied. Further, when the soil is so healthy,fewer pests attack the crops next spring and this also eliminates the need to apply expensive and toxic pesticides! What a great example of Permaculture. Let's all encourage wildlife to come and visit our own gardens...for fertility and health's sake!
