Some rare birds are showing up in the Chicago area.
Experts say many of the ducks have flown far from their usual habitats in search of food. But some were grounded by recent snowstorms and unusually brutal weather conditions
The Slaty Backed Gull is usually found in near Japan and the Aleutian island, but the duck was spotted a in Libertyville a couple days ago.
In less harsh winters, many of the ducks would be farther out on the lake where few would see them.
