Duck nests to get some cradling
Great Lakes effort might help mallards make way to S.C.

More than a mile of rebar will be cut into 900 cradles and shipped to the eastern Great Lakes to hold wire mesh henhouses in a curious project aimed at putting more mallard ducks in the streams and skies of South Carolina.
The project is the work of the Flyway Foundation, formed in February by 200 avid duck hun-ters, to "enhance the population of mallards" that winter in the state and fly off to nest in the Great Lakes region.
The cradles will make it easier to set, repair and maintain the mesh nesting tubes placed on posts in open water in lake coves, farm ponds and parks to protect eggs and hatchlings from predators such as raccoons. A study as part of the project will gauge its breeding success; only one of every five hatchlings are said to survive in wild, open ground nests.
The mallard is a larger cousin of the wood duck, a year-round Lowcountry waterfowl that makes use of the familiar wooden duck boxes along rivers. The mallard is the most popular game duck.
Foundation director and Columbia attorney Stephen Hucks described the nests as a way to bolster a population dwindling in the Southeast because of shrinking wetland habitat. A foundation news release estimates the South Carolina mallard population has declined from 250,000 in the 1950s to fewer than 10,000 today.
"I've got two kids and a third on the way. If the trend continues, they'll never know what I've enjoyed," he said.
The idea left U.S. Fish and Wildlife migratory bird management biologist Al Manville shaking his head. The mallard population might be declining sharply in South Carolina, but the population tends to fluctuate and overall is in relatively good shape.
Meanwhile, wading birds such as the wood stock or the nearly extinct whooping crane, which use roughly the same habitat, are in far more serious trouble, he said. Fewer than 500 whooping cranes are known to be alive today. So are songbirds that travel South Carolina, such as Kirkland's warbler, with fewer than 750 breeding pairs worldwide.
"Mallards are not a species in trouble by any means. They're everywhere. Let's put our effort into the bigger issue. More than one-quarter of the birds we're mandated to manage are in trouble and in some areas serious decline," he said.
"I would suggest protecting habitat as the best way to go about this. We're losing wetlands at an unprecedented rate."
