Invasive snails that threaten waterfowl have expanded their range to a small cold water stream in Langlade County, according to a report released Tuesday by the Department of Natural Resources.
The snails were discovered in Elton Creek, a small stream.
Faucet snails harbor parasites that are deadly to waterfowl — primarily coots and scaup, also known as bluebills. DNR staff collected routine samples from the creek in December, and the snails were identified in those samples in May. One snail hosted the waterfowl parasite.
