LANSING — That short burst of tweets you hear from wrens might be the best way to tell if they’re near, but it isn’t the only way. A good way to predict the bird populations in the Great Lakes is to listen not for the songs of wrens, but for the roar of car engines. A recent study in the Journal of the Society of Wetland Scientists shows where humans are and where wren populations should be – but aren’t. One of the broadest research projects on two species of wrens in the Great Lakes region found that urban development has a primary influence on where the birds live. For the most part, where you find people is where you likely won’t find wrens.
