Mountain Weasel Interesting Facts

What type of animal is a mountain weasel?

The mountain weasel (Mustela altaica) is a type of weasel. It is also known as the Altai weasel, pale weasel, or solongoi.

What class of animal does a mountain weasel belong to?

The Mustela altaica belongs to a class of mammals.

How many mountain weasels are there in the world?

The population of Pale weasel Altai is unknown. Weasels can be found in many different ranges of habitats over most of the UK, and their population is estimated to be around 450,000.

Where does a mountain weasel live?

The Altai weasel, a near-threatened species, lives in the woods. It typically lives in the UK, though it is also spotted very frequently in Scotland, Ireland, and the fringes of countries like France and Italy.

What is a mountain weasel's habitat?

Mountain weasels mainly prefer high-altitude habitats, including stony tundra and green woods. Rock crevices, abandoned burrows, and tree trunks are common places for this animal to relax. Their habitat range could be in close proximity to human settlements.

Who do mountain weasels live with?

The mountain weasel, Mustela altaica, species is mostly solitary except at the time of mating. If we talk about behavior, the mountain weasel is primarily nocturnal and is extremely fast and nimble, capable of swimming, climbing, and running. The short legs and long bodies of these animals enable them to be extremely agile.

How long does a mountain weasel live?

The lifespan of a mountain weasel (genus: Mustela) is not known. But typically, weasel species can live up to 10 years, though most only live three to five years.

How do they reproduce?

Although the Altai weasel's mating method and reproduction are unclear, other animals in the same genus are polygynous: one male and several females. They only reproduce yearly, and males compete fiercely for females. Mating takes place around February-March, and generally, the young are born during May.

The gestation period takes 30–49 days. But the duration of gestation and childbirth can be adjusted because the species is able to defer implantation.

The female can reproduce, and the egg gets fertilized; however, the egg doesn't adhere to the endometrium inside the uterus of the female to prolong the pregnancy until resources to support the pregnancy and nourish the young become available.

The litter size is one to eight young. The young are conceived altricially, in need of food, and reliant on the mother.

The young's eyes remain closed, and they haven't well-developed fur. Lactation will last around two months, following which the young grow self-sufficient but stay with their siblings until fall. When these young become slightly less than a year of age, they become able for reproduction in the next season.

What is their conservation status?

The conservation status of mountain weasel Mustela altaica species is Near Threatened listed by IUCN due to their significant decline.

Would they make a good pet?

Are mountain weasels endangered?

As per the IUCN, the mountain weasel endangerment status is Near Threatened because it is thought to be in significant decline that needs monitoring mainly due to habitat as well as resource degradation. The absence of prey species is the most serious threat to this species.

Although there is no special conservation policy or project for the Altai weasel, several other projects involve it or benefit it. The Kazakhstan nature reserve, for example, preserves a wide range of animals. Weasels are also helped by programs that conserve pikas and other smaller animals which are eaten by the weasels.

Another option could be setting aside corridors between grazing grounds for the weasel to travel across or between forests to grab their prey without disrupting the livestock's grazing fields.
