Cross traffic is heavy at night here on Sand Run Parkway. That’s why barriers are closing the road.

The traffic is hard to see though; it’s a combination of spotted salamanders, wood frogs and spring peepers. Biologist Ramsey Langford from the Summit County Metro Parks says these amphibians are migrating back to their birthplace, a vernal pool.

A few months after hatching “they will live out the next two to three years on land until they hit sexual maturity and then head back to the pool they once came from," he explains.

The park has been closing the road for a short period each spring for the last 10 years to prevent automobiles from killing hundreds of the amphibians.

Vying for attention
It's the spring peepers and wood frogs are making all racket.Those are males trying to attract females. “It’s sort of like the loudest call gets the most females,” says Langford.

But Peepers can suddenly drop their calls to complete silence, apparently when they suspect a predator is near. They are only about an inch long.

Not so different from rock stars.

But spotted salamanders can live 30 years and grow to 6 or 8 inches long.   

Langford recommends visitors don't touch the amphibians because it can harm the animals.  “Look with your eyes not with your hands.”

The parade of critters so they're less likely to be eaten by birds.
