TAMPA — The U.S. Postal Service today released a set of four new stamps that depicts three of the season’s most adorable critters: the eastern chipmunk, eastern gray squirrel and American red squirrel.

The stamps made their debut at the Milcopex stamp show in Brookfield, WI.

Squirrels and chipmunks are very resourceful. Some hoard food supplies for the winter; others forage for food in the colder months. But one thing they have in common is making time for plenty of naps.

When winter hits, the eastern gray squirrel (Sciurus carolinensis) scopes out snacks and builds high-up nests called dreys, some of which are sturdy enough to withstand full-on blizzard conditions. They are guided by a keen sense of smell and can often be found tunneling through deep snow to reach hidden stashes of food.

The American red squirrel (Tamiasciurus hudsonicus) shows off its new winter gear fashion with fluffy ear tufts and a thicker coat when the temperature drops. It’s constantly hunting for its favorite foods such as pine nuts, berries, sap and other squirrelly delicacies. Much like its eastern gray squirrel counterpart, it retreats to a drey or other cozy spot in a tree on especially frigid days. It will occasionally go underground to rest and get out of the cold.

The eastern chipmunk (Tamias striatus) is the proactive member of this group. It preps for winter during the warmer months by stockpiling its burrow full of nuts and seeds. Once the cold weather hits, it settles down for long winter naps, waking up from time to time for a snack. On some milder winter days, it may pop out of its burrow to stretch its legs for a bit before scampering back to its warm and dry underground home.

Whether dashing through the snow or snoozing the day away, these small survivors have winter all figured out. And now they’re ready to bring a little extra pep to the mail — one scamper at a time.
