Baby news: Four wolverine kits born in Ranua Wildlife Park

Four wolverine kits were born at Ranua Wildlife Park in early February. A litter of four is considered large for wolverines. The kits are now approximately one month old.

At birth, wolverine kits are white and very small—so small that when the mother curls up, she is able to protect all four kits at once. Over the past month, the kits have already grown significantly. During the first weeks, the mother, Khurma, spent virtually all of her time in the den with the kits, but she now occasionally leaves them for short periods to feed and explore her surroundings.

The early kit stage is a sensitive time, and Khurma is caring for a large family. The lives of the mother and kits are monitored via a den camera, but otherwise the den area is left undisturbed to allow the mother to care for her young in peace. The kits typically remain sheltered in the den until they are around two months old, after which they gradually and cautiously begin to explore the outside world.

The father, Julle, lives within the same enclosure complex but does not take part in rearing the kits. He keeps a respectful distance from the den and allows the mother to care for the young.

“The birth of wolverine kits is a great joy for us and an important success, as breeding wolverines in human care is often challenging,” says Heini Niinimäki, Zoological Director and Veterinarian at Ranua Wildlife Park. “Above all, following the kits’ development is rewarding both for our staff and for visitors.”

An important success in conservation work

The wolverines at Ranua Wildlife Park are part of the EAZA Ex situ Programme (EEP) coordinated by the European Association of Zoos and Aquaria (EAZA). The aim of the programme is to maintain, over the long term, a sufficiently large, genetically diverse and viable population.

The kits have been eagerly awaited, as the offspring of these parents are considered genetically especially valuable. This is the second litter for Khurma and Julle: in 2024, the pair had their first litter of three kits. Prior to that, wolverines were last born in zoological care in Finland in 2016—also at Ranua.

Wolverines are a species that is sensitive to conditions and often easily disturbed. Their reproduction also involves delayed implantation, meaning that after fertilisation the embryo remains dormant and begins developing later only if conditions are favourable overall. At Ranua, breeding success is supported by a relatively calm environment and a climate well suited to the species.

“This new and larger litter indicates that conditions, the animals’ individual characteristics, and the pair’s compatibility have all been well aligned,” Niinimäki says.

When can visitors see the kits?

The young wolverines are expected to begin making their first small exploratory trips outside the den in April–May. Throughout spring and summer, visitors will have a great opportunity to follow the kits’ growth and their cautious first steps in the enclosure—always respecting the animals’ need for peace and space.

In the mean time, take another peek to the den. In these clips the litter is 5 weeks old.
