Ranua wildlife park welcomes unusually large wolverine litter

A female wolverine at Ranua Wildlife Park in northern Finland has given birth to an exceptionally large litter of four cubs, the park announced on Monday.

The cubs, all male and now roughly one month old, were born in early February to a mother named Khurma. According to the park’s veterinary director Heini Niinimäki, wolverine breeding in captivity is often challenging due to the species’ sensitivity to disturbances and delayed embryonic development.

“Successful wolverine births are a major achievement for us,” Niinimäki said, noting that favourable conditions—including a calm environment and suitable climate—have supported reproduction at the park.

This is the second litter for Khurma and her mate Julle, following a trio of male cubs born in 2024. Niinimäki attributed the larger litter to optimal conditions and strong compatibility between the pair.

The cubs, born white and blind, remain in their den under close monitoring via nest cameras. Staff avoid direct interference to allow the mother to care for them undisturbed. The cubs are expected to begin exploring outside the den between April and May, gradually venturing into the enclosure as they approach two months of age.
