Relatively rare goose for the county, but a Code 2 in part due to numerous other sightings in the area. eBird data show single bird sightings mostly on the West side of the county, except for the 17 bird flyover I lucked in to.
This is another bird that is likely to be mixed in with some Canada Geese. Careful study of this bird, and Ross's Goose should be done when seeing an all white bird with black wingtips.
