LANSING – Endangered birds in Michigan are sporting tiny locator backpacks to help determine how they get to their winter homes. During the summer, Kirtland’s warblers nest only in certain areas of Michigan, Wisconsin and Ontario, according to the Department of Natural Resources (DNR). In Michigan, they are found in 13 counties, from Lake Huron west to Kalkaska County and from Presque Isle County south to Ogemaw County. During the winter they migrate south to the Bahamas. The question is, how do they get there?
