Past Pieces: “You little weasel!”

Snapshot Wisconsin volunteers have identified a total of 493 triggers of weasels over the course of the project. Although we don’t distinguish between species in our classifications, Wisconsin is home to three distinct species: the long-tailed weasel, short-tailed weasel and least weasel. One of them is known as the smallest carnivore in North America, read through the post to find out which species it is!

The article below, “You little weasel!” by Christian W. Cold, was originally published in Wisconsin Natural Resources magazine in February 1998. After reading, you may find that these mysterious critters will weasel their way into your liking.

@ Gregory Scott

Survival is the objective of the day, every day, if you are little. And danger is always nearby when you are a weasel. Creatures larger than you are out there, listening, and watching with hungry eyes. You avoid their attention by remaining tentative; carefully choosing when to move. You travel about your 40-acre universe in a state of perpetual tension, keenly aware of every sound, every smell and every motion around you

Finding a meal is work. Avoiding becoming a meal is even tougher. As both hunter and hunted, you bear the risks by constantly moving. If you tarry, you die; if your prey hesitates, it dies. Your quarry takes many forms – most are smaller than you, but similar in appearance. Their scent lingers everywhere, but they vanish when you arrive. Your prey cringes in terror in your presence…with good reason

Weasels have an image problem. We are quick to condemn them as corrupt, greedy little villains who sneak around and kill with deadly efficiency for no reason whatsoever. We’ve historically viewed weasels as pests, varmints or scraps of fur only suitable for a decorative trim on collar or cuff. It’s a wonder that weasels have endured such a hostile world.In fact, weasels are marvelously successful. They persist by being alert, inquisitive, tenacious and most importantly, small.

Hunters of mice

Weasels are members of a large and diverse family of mammals known as mustelids, which include mink, martens, fishers and skunks. If you shake the family tree harder, badgers, wolverines and otters are also distant relatives. As a clan, the mustelids are typically slender, elongated animals with short legs, a small head and short fur. Their needle-like canine teeth are designed to pierce the throat and brain of small animals, particularly rodents.

The species name, Mustela, means “one who carries off mice,” and all weasels are accomplished mousers. However, to reap the benefits of their small, dynamic world, the weasels can’t afford to be picky eaters. The bill-of-fare includes chipmunks, ground squirrels, insects, small birds, frogs and snakes. Shrews form an important part of their winter diet. Though they occasionally eat fish, weasels are poor swimmers, paddling clumsily with their backs arched out of water.

Weasels have an earned reputation as fierce, efficient predators that will attack animals several times their own size. A four-ounce weasel can kill a four-pound rabbit. The weasel’s habit of killing larger prey and killing several animals at a time stems from its habit of storing or caching surplus food for later use.

Small caches scattered about can provide a series of small meals. Incidents of wholesale slaughter in poultry yards are likely triggered when a weasel goes into “hunt mode” in the unnatural setting of finding several confined prey with no avenue of escape

Weasel biology

Three species of true weasels live in North America. The largest, at 18 inches, is the long-tailed weasel. Long-tails occupy diverse habitats throughout the United States and into Central America. They appear to prefer patchy landscapes of mixed habitats intersected by streams and small rivers. The smaller short-tailed weasel or “ermine” is found in heavily-forested areas and brushy areas of Canada, the northeastern states, the Upper Midwest and Northwestern forests. Smallest of the tribe is the least weasel, a pugnacious dynamo who claims the title as North America’s smallest carnivore. The least weasel is infrequently observed in the marshes and damp meadow. I once inadvertently caught one in a repeating mouse trp at the Mead Wildlife Area in Marathon County in the Upper Great lakes region.

The pelts of all three weasels are brownish and are replaced by a winter white coat that begins to appear by the first of November. The long-tail and short-tail sport a black tip on their tails; an attribute which may confound the striking accuracy of avian predators. Hawks, owls, eagles, foxes, coyotes, bobcats, lynx and domestic cats will eat a weasel – provided they can catch one! The larger mustelids such as mink, marten and fisher pursue small weasels with frightful determination. Size and agility are not the weasel’s only defense. A pungent musk, secreted from an anal gland, may repel or nauseate all but the most persistent of predators.

Weasels sexually mature before their first birthday. A typical litter of six or seven young is born each year and is cared for by both parents. Weasels reaching five to six years are regarded as fully mature. Individuals as old as 10 are considered ancient

How to find a weasel

Weasels are easiest to see in winter when leaf cover is gone and a thin layer of tracking snow will show their whereabouts in the neighborhood. Weasels leave staggered pairs of little footprints placed in a bounding gait fashion. Look for sudden right-angle turns in the tracks that often disappear beneath the snow and reappear at a considerable distance.

Weasels hunt aggressively during the cold, hungry months of winter. Their intense curiosity and insatiable appetite leads them to range widely in a seemingly erratic fashion. They seldom travel far in any one direction. A weasel will stop to poke its little head into every hole, nook and cranny it can probe. Its slender body can squeeze into lairs and runways of mice. Within these subterranean passages the weasel’s sensitive nose and ears will quickly locate the tenants.

Weasels often den in an abandoned (or usurped!) home of a chipmunk or ground squirrel, in a hollow log or under a pile of rubble. The nest chamber is often lined with fine grasses, feathers or the fur of the “former” occupants. Weasels are remarkably clean animals that will not defecate in their quarters. They designate a separate latrine area.

These sleek, little hunters are both feared and respected. If you are a weasel among mice, is it merely “a terrible efficiency” to be the animal that eats its neighbors? I think not. The weasel was designed by the limits of its environment to eat the flesh of others. It must kill to see another day. As humans, we tend to leave that grisly chore to the butcher, but the weasel assumes considerable risk and expends considerable energy just surviving.

The next time you get to see these ambitious little bundles of energy, take a moment to view the world from their perspective. Be thankful that at your comparative size, you can afford to wish them “good hunting.”

January Volunteer of the Month

January’s Volunteer of the Month is
Duanne from Vilas County!

January’s Volunteer of the Month goes to Duanne from Vilas County! Duanne is a long-time citizen scientist who has participated in a variety of projects including wolf tracking, lake monitoring, Snapshot Wisconsin and more. As a 50+ year bow hunting veteran, he immediately fell in love with monitoring what was going on in the natural world when he wasn’t there.

Duanne has spent more than two years monitoring trail cameras in the Clam Lake elk reintroduction area, though his first experience camera trapping came when his son gifted him a trail camera over 20 years ago. When asked about his favorite part of participating in Snapshot Wisconsin, Duanne responded, “probably just another excuse to get out in the woods” – we couldn’t agree more! He also shared that he enjoys reviewing and editing the pictures as each is a new opportunity to see something exciting. Below is a photo of the first elk that Duanne saw on one of his Snapshot Wisconsin cameras, which is quite the impressive looking buck!

Happy New Year!

Happy Near Year from the Snapshot Wisconsin team! 

2018 brought a year of tremendous growth for Snapshot Wisconsin, and we couldn’t have done it without you! Since the statewide launch in August this year, the project has reached every Wisconsin county with over 1500 volunteers. We cannot thank you enough for your help making Snapshot Wisconsin the success that it is today. Happy New Year, and we can’t wait to see what 2019 brings!

December #SuperSnap

Can you guess who took the spot light for our December #SuperSnap? That “bobbed” tail may give it away!

The December #SuperSnap, nominated by @AUK, goes to a bobcat (Lynx rufus) from Jackson County. Often confused with their larger cousins, the Canada Lynx, bobcats can be distinguished by their short tail, tufted ears and white underbelly. They are the most abundant wildcat found in the United States, so keep an eye out for bobcats on your trail cameras!
