Feathered Farmland Friends of the Fens

The wind power industry has had close to zero success designing bird and bat-safe turbines, but nascent research by ecologists nevertheless shows that wind power is compatible with local ecology. Case in point: today’s report in Britain’s Journal of Applied Ecology on wind farms and birds in the East Anglian fens.

Mark Whittingham and fellow ecologists from Newcastle University surveyed birds on farmland around two wind farms in the fens and recorded almost 3,000 birds from 23 different species. Among them are five endangered species: the yellowhammer, the Eurasian tree sparrow, the corn bunting, the Eurasian skylark and the common reed bunting.

Whittingham and company found the wind turbines had no effect on the birds’ distribution with the exception of common pheasants. “This is the first evidence suggesting that the present and future location of large numbers of wind turbines on European farmland is unlikely to have detrimental effects on farmland birds,” says Whittingham.

Plenty of questions remain. For example, a comprehensive $15 million study of Denmark’s large offshore wind farms published last winter showed seabirds to be remarkably adept at avoiding offshore installations, but ecologists remain concerned that the 10,000 megawatts of offshore wind power that Germany hopes to install by 2020 could scare off populations of endangered loons along Germany’s North Sea coast.

Even the Newcastle study was conducted last winter and must be followed up to confirm there are no unexpected impacts during the breeding season.

The wind industry would do well to continue working on newer, safer technology.
