Does the Eurasian lynx avoid strictly cold water?

Co-author Irina Rotenko

It looks like among both amateurs and researchers of the Eurasian lynx an opinion is wide-spread that the species strictly avoids cold water, in particular crossing cold waters of streams by swimming. Before camera-trapping by dealing with lynxes already quite a lot (study on population dynamics and diet in connection with changes in prey supply), we think like that, too.

Story of consuming of four carcasses of roe deer killed by adult male lynx with implication for a role of adult male in feeding of kittens

Co-author Irina Rotenko

One of the most important pressing questions of the Eurasian lynx behaviour and ecology is a role of an adult male in family life. It is well known that an adult male lynx accepts from one to three adult females in its home range. So, it may be up to three lynx mothers with kittens in the territory that is occupied by an adult male lynx. In our case in Naliboki Forest (central-western Belarus) there were usually two such families, rarer one or three families inside a territory of an adult male lynx.

Usage of big nest on tree as a calling-resting-watching platform by lynxes

Co-author Irina Rotenko

In 2019-2020 in Naliboki Forest (central-western Belarus) by means of registration of tracks at tree butt and claw marks on trunk we found that in February-April lynxes used climbing on two pine trees which had a raven nest. After several lynx climbing the nests were almost destroyed and finally disappeared. We could not take photos of that lynx behaviour, however, all the signs, that we observed, definitely suggested that the lynxes were on the nests.

Using of cavity-shelters by Eurasian lynxes in Belarus as non-rocky forested region

Coauthor Irina Rotenko

In mountain rocky regions it is well-known that Eurasian lynxes use cavity-shelters that situated under or between rocks, whereas in non-rocky forested regions such a behaviour of the species is not so evident. Recently we found that lynxes use cavity-shelters in such habitats a lot, too. We investigated this question on lynx behaviour in Naliboki Forest (central-western Belarus) by means of camera-trapping, snowtracking and detailed inspection of lynx habitats with checking for lynx hair.

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.

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.

Documentation of using badger sett by lynx mother with small kittens

Coauthor Irina Rotenko

In our previous studies we registered usage of badger setts by mother lynx with small kittens in June-August (mainly by track registrations), as well as much interest of pregnant female lynxes to badger setts (by camera trapping). We supposed that badger sett is a quite common den of the Eurasian lynx. Nevertheless, a good documentation of using badger sett by lynx mother with small kittens was absent in our materials. We had some photos of that behaviour only.

Is a burrow a suitable lair for mother lynx?

Coauthor Irina Rotenko

Recently in Naliboki Forest in the central-western part of Belarus we registered when heavily pregnant female lynx was inspecting the last year burrow-den of wolves plausibly as one of potential sites for her denning.

Sleeping by Eurasian lynxes

Coauthor Irina Rotenko

Together with Wild Naliboki team, Belgium and Maximilian Hetzer, Germany we investigate the poorly known ecological questions and behavioral traits of the Eurasian lynx in Naliboki Forest, the central-western Belarus (Sidorovich et al., 2018). One of such a question how much lynxes sleep during twenty-four hours.
