Energy advocates are eyeing wind turbines to create electricity along the North Shore. Bird researchers are studying where the migrating birds fly most often. Once they know, they can advise the energy people on areas to avoid. ..."We know we have a globally significant raptor migration route here that [wind turbines] could have a serious impact on if not done correctly,'' Niemi said. "But we also have these hundreds of thousands, perhaps millions of passerines [small birds] that come through here at pretty much the same time that most people don't even know about. We have to look out for them, too.''
