Weasels

Weasels are more than just cute; they are also fearless members of the Mustelidae family. These tiny creatures with brown and white furs are adorable when they move or run to play tactics. Other than cuteness, they are proficient at climbing and swimming. One of their unique abilities is that they fit themselves in burrows to capture prey.

Species of Weasel

Mustelidae is further divided into 17 species of Weasels present under the given genera. These include species of ermine, ferret and polecats. Short-tailed Weasels are most abundant in North America. From short-tailed weasels to ermine and polecats, they are adorable creatures. Except for Antarctica and Australia their species are found almost everywhere on all continents.

Physical Characteristics

Size and Weight: They are 20 to 30 cm long and weigh 80 to 350 grams. Females are twice as short as males. As a short mammal, Least Weasels are 6 to 8.5 inches in length and carry a weight of 25g.

Speed: Weasels are quick mammals and fast runners covering up to 15 miles per hour.

Dentition and claws: Weasels are carnivores with sharp teeth, carnassials, and small molars. Their claws are sharp, and each contains five toes.

Body and Tail: They are quick mammals with petite and slender flexible bodies, long necks, short heads, short legs, and sharp claws. Some species have short tails, while some have long tails.

Fur Colouration: Weasels’ body is adapted to its habitat. Their skin is soft and dense. Their fur ranges from brown to dark brown and blackish. Some have yellow underbellies, while others have black-tipped tails.

Distribution and Habitat

Geographically, these soft-eyed mammals are found in South and North Asia and America. They also spend their lives on the islands From Russia and Africa to Japan and Europe. In some areas of North America, there are small numbers due to the inappropriate environment.

Their habitats vary in species, and the habitat selection depends on the prey abundance. In winter, they spend their lives in cold regions. They live in marshes, woodlands, mountainous regions and rock crevices. Some reside in semi-aquatic and semi-timbered urban areas, thickets and areas near water. They maintain their habitat through their behaviour, and it also depends on climate.

Diet and Digestion

Weasels are agile carnivores. They eat rodents, voles, insects, mice reptiles, and frogs. They look small but abruptly feed on rabbits. They eat fruits as a healthy diet. Somehow, Weasels attack chicken coops. They consume birds and their eggs and are not capable of storing fats in their bodies, which is why they consume as much food as they can. In contrast, they are agile mammals. Their metabolic rate is rapid, and they consume food immediately.

Behavioural Adaptations

Weasels are brown from head to back and tail and white from underbellies. Their skin entirely becomes white during winter.

Hunting Behaviour

These tiny creatures have flexible and tube-shaped bodies that are excellent for capturing prey. They are solitary hunters, enter in burrows and crevices, kill mice efficiently and feed them. After biting prey, they quickly digest it and save much food immediately for later use. In Weasel species, ferrets and stoats are clumsy and perform a unique dance known as Weasel War Dance. Through dance, they mesmerise their prey and quickly attack it.

Social Behaviour

Weasels are active solitary structured members of the Mustelidae family. They defend their territories by secreting scent glands. Weasels communicate through scent marking and using vocalisations of squealing and growling, which serves as a warning for predators.

Camouflage

In winter, coats of stoats or ermine become dense, thick and white. Their bodies are camouflaged when they are covered with snow. Brown-bodied Weasels blend with mountains, rocks and Earth. In addition, the light colours of their underbellies blend with grass, shrubs and bushes.

Reproduction and Parenting

According to studies, their species mate in the summer season. Their gestation period is 35 days, while implantation in short-tailed Weasels is delayed and occurs in 10 months during winter. They weigh about 3 grams when they are born. Males are about multiple females at a time. They can breed at 3 months. In addition, Males are larger than females.

Yearly Weasels give birth to a single litter or one to two kits. After mating, males can leave the territory. Female weasels alone raise their kits. When kits are born, they look sleek, blind and deaf. They are adults for two to three months and spend time with their mothers. They raise their young as a single mother and teach them about hunting techniques, diet behaviour and movement.

Mortality and Lifespan

The annual survival rate of weasels is 70 to 90%. Their heart beats 400 to 500 times a minute. In captivity, they can live up to 8 years, while they spend 4 years in the wild. Hardly Long-tailed mammals can reach 1 year of life.

Ecological Importance

Weasels are an important species for the ecosystem of Earth. These most diminutive bold hunters help maintain our land or ecosystem by preying on rodents, reptiles, and insects. As an apex predator, they eat rabbits to control their population and prevent their habitat by killing them. After all, they are skilled mammals.

Conservation Status and Efforts

According to the red list of the International Union of Council, species of Weasels are least concerned. Their coats and hair are used in clothing or brush making. They are suffering from human-weasel conflict. We can save them by providing a pure habitat. A place where they live independently and no one can harm them. In that way, we protect them from killing.

Their diet also includes insects, reptiles, frogs, birds, and eggs, and they can hunt prey larger than themselves, such as rabbits. Occasionally, they consume fruits as a supplement. Due to their high metabolism, they need to eat frequently and may consume up to 40% of their body weight daily.

What makes weasels unique?

Weasels are unique due to their slender, flexible bodies that allow them to squeeze into narrow spaces to catch prey inaccessible to larger predators. They are agile climbers and swimmers and can run up to 15 miles per hour. Some species perform a “Weasel War Dance” to confuse prey, and they can change their fur color with the seasons for camouflage, turning white in snowy environments.

What is good about weasels?

Weasels play a crucial role in controlling populations of rodents and insects, which helps reduce crop damage and the spread of diseases. By maintaining ecological balance, they contribute to biodiversity and prevent overpopulation of certain species like rabbits, which can lead to habitat degradation. They are integral to the food chain as both predators and prey.

Are weasels friendly?

Weasels are wild animals and are not typically friendly towards humans. They are solitary creatures that can be fierce when threatened and generally avoid human interaction. While important to the ecosystem, they are not domesticated and may come into conflict with humans by raiding poultry houses.
