The DNR is asking for help in tracking chimney swifts.
Wisconsin’s Department of Natural Resources on Friday asked for volunteers to help track the small birds. Swifts are small, unique birds that fly all day long. The DNR says their chittering sounds can be heard starting mid-April into early May as they return from their winter homes in South America. But their numbers are shrinking, by one count they are down 70 percent over the past 50 years. You can find out more about the swift count at the DNR’s website.
