During the winter of 2017-2018 in Naliboki Forest we (Naust Eco Station and Wild Naliboki) have found that Eurasian lynxes climbed rather high pine trees to emit mating calls during the species mating season (Sidorovich et al., 2018). In total, during February and March 2018, we registered four such trees of the Scotch pine, on which adult male lynxes climbed for about 17-26 meters high. The density of the local lynx population was about 4-5 inds per 100 km2 i.e. about 80 per almost 2000 km2. We have evaluated that phenomenon of calling by lynxes from a tall tree top as a mating call, also taking into account that it was registered in the lynx mating season in Belarus (mid-February-early April).
This post addresses the question of poorly known social contacts in the Eurasian lynxes exclusive of between-mate relationships and mother-kittens behaviour. In the book “Unknown Eurasian lynx Lynx lynx: New findings on the species ecology and behaviour” by Vadim Sidorovich, Jan Gouwy and Irina Rotenko (2019) we have stated that the species is not a solitary, but it is surprisingly social carnivore.
This post adverts the recent shift in the habitat-related lynx distribution for usage of openings and the lynx reaction to get back to forest in connection with the considerable changes in the wolf number in Naliboki Forest.

During quite a lot of studies on the Eurasian lynx in Naliboki Forest and Paazierre Forest we realized that this species is still so poorly known (Sidorovich et al., 2019). Even a simple lynx pee hides several non-studied questions that were raised during investigation the species behavior. Several curious pee-related phenomena were registered that was already some achievement, but for every one still there is a pressing question how such a pee regime is possible on a morph-physiological level i.e. by means of which morph-physiological adaptations of the species. Maybe somebody, after reading the post, will try to investigate the lynx pee questions.

In Naliboki Forest adult lynxes particularly males are known as killers of the vulnerable categories of wolves such as pups, lonely living subadults and heavily pregnant females (Sidorovich et al., 2019). Also, lynxes may be a valuable competitor for wolves in their exploiting of the roe deer and beaver populations. Study on the interference of wolves and lynxes in Naliboki Forest suggested that wolves disagree with presence of lynxes in the habitats, and they behave aggressively towards lynxes, too. Lynxes feel safe in forest habitats, whereas they mainly avoid openings, when wolves are common in the habitats and where they may be killed by a wolf pack, because there are no trees to escape.

In snowless period spots with open sand, peat or other ground types are outstanding elements in the habitat structure in forested areas such as Belarus, and many mammal species tend to use them for territorial marking. Among these mammal species first of all it may be mentioned red deer, bison, wolf and lynx.
This post addresses the intriguing question of a great interest of wolves, red foxes and deer to lynx marking points, but there is no an opposite reaction of lynxes to marking by the above species. It is easy to realize, why red deer, roe deer and red foxes pay so much attention – lynxes kill them often. Therefore, any information about lynx distribution and status (adult or young, sex, welfare etc.) are important for these victim species. The same is for wolves. Adult lynxes not rarely kill wolves from vulnerable categories such as pups, heavily pregnant females, just small individuals (Sidorovich et al., 2018). However why do lynxes pay a minimal attention to marking by deer and even by wolves?
