Invasive snail kills birds with parasitic help

In a scientific supermove U.S geologists and Michigan biologists are combining their power to map out areas impacted by invasive species.

In an ironic twist on the food web, an invasive snail has become a bird killer.

The faucet snail is a half inch brown or black creature. It’s also the carrier of a lethal parasite.

Dr. Don Uzarski is a biologist at Central Michigan University. He says this snail is bad news.

“It’s an intermediate host for a parasite. What happens when waterfowl consume an infected snail, the adult trematode then attacks the internal organs of the duck, ultimately killing the organism.”

In an attempt to control the faucet snail populations, biologists from CMU and geologists from the United States Geological Survey have combined efforts to map out known habitats.

Uzarski says so far efforts to kill the snails have not made a dent in their numbers.

At this point the parasite is only known to effect waterfowl.
