Ostrava Zoo Welcomes Rare Kolonok – New Species Arrives

The Ostrava Zoo in the Czech Republic has added a new, and relatively rare, species to its collection: the Asiatic jackal, known as the kolonok. A four-year-old male arrived from Zoo Erfurt in Germany, marking the first time this animal has been housed at the Ostrava facility.

A Species Under Pressure

The addition of the kolonok is significant due to the species’ limited presence in European zoos. Currently, only 17 institutions across Europe house a total of 47 individuals. Matěj Vrúbel, the Ostrava Zoo’s inspector for carnivore breeding, explained the zoo’s interest in the species stems from its relatively rapid reproductive rate and the vulnerability of small populations to extinction in human care.

Habitat Transition

The new arrival is currently residing in the upper level of the Gibbon Temple. Plans are in place to eventually grant him access to the lower level, an area previously occupied by grey-bellied squirrels. According to Vrúbel, the previous habitat proved unsuitable for the squirrels despite multiple attempts at modification. The kolonok, however, is expected to thrive, particularly given its ability to withstand colder climates.

Did You Know? The kolonok’s natural range spans across a vast geographical area, including parts of Russia, Mongolia, Korea, China, and Southeast Asia.

Understanding the Kolonok

The kolonok is native to a diverse range of environments, including forests, steppes, and mountainous regions across central and eastern Russia, Mongolia, and several countries in Asia. Its diet is varied, consisting primarily of small mammals like rodents, but also including amphibians, birds, eggs, fish, invertebrates, and even fruits. The animal is largely nocturnal, resting during the day in dens under tree roots, within tree trunks, or beneath rocky overhangs.

Expert Insight: The Ostrava Zoo’s decision to prioritize the kolonok’s breeding program reflects a growing awareness within the zoological community of the importance of maintaining genetic diversity within vulnerable species, even those not currently classified as critically endangered. Focusing on species with higher reproductive rates can provide a buffer against potential population declines.

What’s Next?

The zoo’s success with the kolonok could lead to increased participation in collaborative breeding programmes with other European institutions. If the male kolonok adapts well to his new environment, the zoo may seek to introduce a female to establish a breeding pair. A successful breeding program could contribute to the long-term sustainability of the species within human care, and potentially support future reintroduction efforts, though such initiatives are not currently planned.

Frequently Asked Questions

What is the current population of kolonoks in European zoos?

Currently, You’ll see 47 kolonoks housed in 17 different zoological institutions across Europe.

Where did the Ostrava Zoo acquire its kolonok?

The Ostrava Zoo obtained a four-year-old male kolonok from Zoo Erfurt in Germany.

Why was the kolonok chosen to inhabit the space previously occupied by grey-bellied squirrels?

The previous habitat proved unsuitable for the grey-bellied squirrels, despite multiple modifications. The kolonok is considered a better fit for the environment, particularly due to its ability to tolerate colder temperatures.

How might the Ostrava Zoo’s efforts contribute to the broader conservation of this species?
