This Little Brown Myotis was radio-tagged at the large Woodard Bay colony. Right away this bat flew 8.5 miles (13 km) to Capitol Lake, and spent the entire night feeding there. The miniature radio-tag weighs only about 1/3 of a gram (1/80 of an ounce) and is gently glued to her fur using a medical adhesive. Although I can sometimes hear it up to a couple of miles away on my tracking radios, when they are skimming the surface of the water feeding on midges and caddis flies, the range is only several hundred meters.
