This week in nature, keep an eye out for groundhogs. Also known as woodchucks, or whistle pigs, these rodents in the squirrel family are active during daylight hours, and are breeding now.

With short, powerful legs and a medium-long, bushy tail, these mammals can grow to more than two-feet long, and weigh as much as 14 pounds.

Groundhogs dig tunnels leading to a nest chamber, three to six feet underground. They hibernate from October until February when they emerge and begin breeding.

In late March, a litter of two to nine young are born naked, blind, and helpless. Their eyes won’t open for four weeks, but by mid-summer they’ll start setting out on their own.

Groundhogs help to mix and aerate soil, and are important home-builders for other animals who use their burrows for dens, such as foxes, skunks, weasels, opossums, and rabbits.

Each year, on Groundhog Day, legend has it, if one particularly famous groundhog sees his shadow, we’ll have six more weeks of winter. No shadow means an early spring.
