Nature Note:Meadow Vole

A meadow vole(Microtus pennsylvanicus) scampered across the driveway one August morning,from under a hedge to under an eastern red cedar.It was a rare sighting of the small mammal,a rodent most people never realise is around.They mainly eat grasses,roots,twigs and other vegetable matter and do not come indoors;nor are they considered a pest.*The meadow vole's colouration is variable,from reddish to blackish brown or gray,and it has a short tail.They range from Northern Canada and Alaska down the Rockies and Appalachians south to New Mexico and Northeast Georgia,favouring meadows,marshes and woodland glades.*These rodents have a system of runways and burrows.Prolific,they nest below ground or under rocks and logs in a grass or shredded bark nest.In winter,they nest under the snow.They are sometimes called field mice,and some species of voles are known for a cyclic buildup and crash of population,keyed to the food supply.*The meadow vole is pretty much of a ghostly creature.In more than 20 years,I have only noted them a handful of times along the Pennsylvania-Maryland border.
