Minnesota researchers are using small audio recording devices to better understand the range and population of red-headed woodpeckers. The bird has seen a precipitous population decline over several decades.
“Red-headed woodpeckers in Minnesota have declined by about 95 percent over the last 50 to 60 years, probably due to habitat loss and conversion to agriculture and development,” University of Minnesota researcher Elena West said.
Scientists want to learn where the bird is doing well, so important habitats can be preserved. |
