Video summary on wolf reproduction, Naliboki Forest, 2020

Coauthor Irina Rotenko

Since the last May we began using video mode in our camera-traps more often in order to create a scientific film about reproduction in wolves in few years. The video sequence you see below is a kind of a report on the video results we gained across breeding of wolves in Naliboki Forest in 2020. In this video you see some interesting moments demonstrating various behaviour of wolf pups and parents during this secretive period.

One more documentation of tree climbing by lynx

Coauthor Irina Rotenko

Recently we documented one more case of tree climbing (in this case maple) by an adult male lynx. The tree height was about 15 meters, and the lynx climbed for the height of 10-12 meters. The tree diameter at the butt was about 80 cm. That was repeated climbing of this tree by lynxes. At least, there were two more climbings.

New findings on warm-season behaviour and ecology in Eurasian lynx

Coauthor Irina Rotenko

Warm-season and in particular summer behaviour and ecology in Eurasian lynxes is fairly unknown. During the last two warm seasons (April-October 2019 and 2020) in Naliboki Forest, central-western Belarus we advanced in investigating of this topic.

Is it possible to distinguish the golden jackal by tracks?

A week ago we took photos and video of golden jackal in Naliboki Forest in the localities of Kukhnja and Hala Balota. See the footprint of that jackal below.

Camera-based tracing of behaviour in a large family of Eurasian lynx in the warm season in Naliboki Forest

Coauthor Irina Rotenko

Last summer and this autumn in Naliboki Forest we traced by means of camera-traps the large family of lynxes that was leaded by known female Aurelia. Aurelija has three kittens this year. In this short post we propose to have a look some interesting situations (nursing, grooming) of the lynx family life that we succeeded to film.

Finally golden jackal has arrived in Naliboki Forest, central-western Belarus

Co-author Irina Rotenko

On sixth November in the localities of Hala Balota and Kukhnja we registered golden jackal by two camera-traps. Applying 10 to almost 80 (mean 40-50) camera-traps since 2014 year-round, this is the first registration of the species in the terrain of Naliboki Forest, central-western Belarus.

The united wolf families in the new homesite after stalking of the pups by lynx

Coauthor Irina Rotenko

This post is the continuation of four recent post about breeding of one wolf group in Naliboki Forest, the central western part of Belarus: (1); (2); (3); (4). After so much disturbance to the wolf family by the lynxes (at least, by two different adult males) in the recent coaching place the families relocated about one kilometre away. Avoiding extra disturbance to the wolf family, we did not search for possible carcasses of pups that could be killed by the lynxes.

Documentation of male lynxes stalking for wolf pups in the family homesites in July-August in Naliboki Forest

Coauthor Irina Rotenko

This post is connected with the recent post about mortality in wolf pups in Naliboki Forest and the whole Belarus. In that post about wolf pup mortality we provided quite a lot information on stalking for wolf pups by lynxes, particularly by adult male lynxes. The most vulnerable period in this kind of lynx-wolf interference starts since mid-July, when still quite small vulnerable pups begin to walk alone rather faraway from the coaching place of the wolf family homesite.

We renew wildlife trips in Naliboki Forest from the Naust Eco Station after the pandemic break

Coauthor Irina Rotenko

Since March we have faced with cancellation of our wildlife trips in Naliboki Forest from the Naust Eco Station because of the pandemic situation. Our research on the wolf and lynx, family life and the maintenance of eco station itself appeared without any financial support. Having some cash accumulation, renting out the guest house and thanks to some donations from our former guests (Jean-louis Bonay, Mika Mäkinen, Gerard Oonk) we were able to live and keep up our research till the late summer. There was no any possibility to accept wildlife travellers from abroad because of the corvid-related lockdown of the European Union, spreading the disease and absence of suitable flights.

Behaviour of wolf pups and parents on the stage, when the pups are 30-100 days old: new knowledge for the European wolves

Coauthor Irina Rotenko

Until wolf pups are about one month old, they stay mainly at dens being taken care of by parents who stay at the den or, at least, in the close proximity. Then wolf pups begin to be more mobile, but very hidden life of a wolf family in the tall and dense vegetation makes hard to learn the pup behaviour in June-July. The topic of wolf pups life when they are about 30-100 days old is still very poorly known in Europe and the whole Eurasia. Smart and careful usage of camera-traps can help in studying the question, while telemetry does not seem to be a right method in this case. In our study, besides camera-trapping we also used several other sources of data that are mentioned below in the post.
