Phenology Report: Voles skitter through subnivean tunnels while owls listen in

The students are bundled against the cold and are pointing to the tunnels.

A group of student phenologists kneels down to examine frozen tunnels in the snow. The tunnels are created by voles eager to reach the nearby bird feeder. Tunnels built in snow are called subnivean tunnels.

KAXE Staff Phenologist John Latimer provides his weekly assessment of nature in Northern Minnesota. This is the week of Dec. 3, 2024.

The winter world might seem still and lifeless, but there are plenty of critters scampering around under the snow and ice.

During this week's phenology report, staff phenologist John Latimer gave us a window into this hidden world, where star-nosed moles investigate aquatic areas, voles construct extensive tunnels under the snowpack, and shrews hunt their prey like tiny ravenous wolves.

(Fun fact: Moles store fat in their tails, so they don't outgrow their tunnels every time conditions are good.)
