Groundhog Day 2017 Celebrated With a Portrait From the National Geographic Photo Ark

February 2, 2017 (Groundhog Day)–By tradition today is when the groundhog (aka woodchuck or whistle-pig) awakes from its winter hibernation to check on the weather. If it sees its shadow it can go back to bed; there will be six more weeks of winter.

A heavy-set rodent weighing as much as 12 pounds, the groundhog fattens up during the summer, quite often feasting on farmer’s crops and residential landscaping, causing it to be regarded by many people as a pest. When the cold weather arrives, groundhogs settle in their burrows to sleep through winter (November to February). During that time their metabolism slows as their pulse and body temperature drop.

You Can Help Make a Difference: Species are disappearing at an alarming rate. But together we can help. The interaction between animals and their environments is the engine that keeps the planet healthy for all of us. But for many species, time is running out. That’s why National Geographic, along with renowned photographer Joel Sartore, is dedicated to finding solutions to save them. The National Geographic Photo Ark is an ambitious project committed to documenting every species in captivity—inspiring people not just to care, but also to help protect these animals for future generations. And, with your support, we’re funding on-the-ground conservation projects focused on those animals in most critical need of protection.

The International Union for the Conservation of Nature (IUCN) assesses the groundhog, Marmota monax, as a species of Least Concern, meaning there are no major threats to its survival. Some people bothered by groundhogs eating their herbs, shrubs and vegetable gardens do take (sometimes drastic) action to get rid of them.

Females produce their young in spring. A litter of around half a dozen groundhogs remains with the mother until summer.

Groundhogs are the largest members of the Sciuridae, the family of animals that includes squirrels, chipmunks, and prairie dogs.

They are thought to have earned their other common names, woodchuck and whistle-pig, from the American Indian name for the animal (wuchak) and from the high-pitched alarm whistle it makes when warning of approaching danger.
