Snow BuntingPlectrophenax nivalis
They sometimes have been called "Snowflakes," and flocks of Snow Buntings may seem like snowflakes as they swirl through the air and then settle on winter fields. South of the Arctic these are strictly winter birds, arriving in late fall, generally departing at the first signs of spring. In summer they retire to barren northern tundra, with some breeding on the northernmost islands of Canada and the mountains of Greenland. In some high Arctic communities, Snow Buntings nest in birdhouses put out for them.
