A vole is a small rodent resembling a mouse but with a stouter body, a shorter hairy tail, a slightly rounder head, and smaller ears and eyes. There are approximately 70 species of voles; they are sometimes known as meadow mice or field mice in North America. The voles, together with the lemmings and the muskrats, form the subfamily Arvicolinae.
Shane, I hope that this is what you are after. As I've not seen a vole I had to to google to get the anwser for you but once I get to Canada I hope to get a photo and will send it back to you. Cheers Shane, and thanks again for taking an interest in what Earthwatch & Alcoa are to help with climate control and the sustainability of our planet.
