American pika
Order : Lagomorpha
Family : Ochotonidae
Species : Ochotona princeps
The pika (Ochotona princeps), a cousin of the rabbit may look like a hamster, but it isn't. It sometimes is known as "whistling hare" because when it dives into its burrow, it emits a high-pitched warning cry. Donald Grayson reports in the current issue of the Journal of Biogeograph that 7 out of 25 historically described American Pika populations in the Great Basin -- the area between the Sierra Nevada and Rocky Mountains, have become extinct at the end of the 20th century. Reasons described are the grazing of livestock and the increase of roads. According to Grayson, the pika populations are totally isolated from each other so they cannot reach other populations. Pikas are also considered to be one of the best early warning systems for detecting global warming. CNN article on the extinction of the American Pika
