Distribution and Habitat
Singing voles are native to Alaska and north-western Canada. They are found from the western coasts, across southern and northern Alaska, but avoid the Alaska Peninsula, the central regions, and much of the northern coast. In the east, they reach as far as the Mackenzie Mountains, being found throughout the Yukon, aside from the northern coasts, and in border regions of the neighboring provinces.
Four subspecies are currently recognised:
- Microtus miurus miurus - Kenai Peninsula
- Microtus miurus cantator - south-eastern Alaska and southern Yukon
- Microtus miurus miuriei - south-western Alaska
- Microtus miurus oreas - northern Alaska and Yukon
Singing voles are found in tundra regions above the tree line. They avoid the most extreme environments within these regions, preferring open, well-drained slopes and rock flats with abundant shrubs and sedges. They feed on arctic plants such as lupines, knotweed, sedges, horsetails, and willows. Their main predators include wolverines, Arctic foxes, stoats, skuas, hawks, and owls.

Famous quotes containing the words distribution and/or habitat:
“The question for the country now is how to secure a more equal distribution of property among the people. There can be no republican institutions with vast masses of property permanently in a few hands, and large masses of voters without property.... Let no man get by inheritance, or by will, more than will produce at four per cent interest an income ... of fifteen thousand dollars] per year, or an estate of five hundred thousand dollars.”
—Rutherford Birchard Hayes (1822–1893)
“Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.”
—William James (1842–1910)
