In Eurasian lynxes there are several age-sex categories, which are strikingly or markedly differed by their life styles. The data that leads us to this conclusion originated from about 2300 km of snowtracking lynxes, study of lynxes with camera-traps (up to 70) and a lot of other various research results. Among them the results of two lynx telemetry projects.
During the winter of 2017-2018 in Naliboki Forest we have found that Eurasian lynxes climbed rather high pine trees (Pinus sylvestris) to emit mating calls during the mating season (Sidorovich, Gouwy & Rotenko 2018). In total, during February and March 2018, we registered four pine trees, on which adult male lynxes climbed for about 17-26 meters high. The density of the local lynx population was about 4-5 individuals per 100 km2 i.e. about 80 on an area of 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).
In an earlier post, we reported several records of surprisingly social behaviour in lynxes: males walking with females outside the mating season and subadults joining mothers with kittens. In the book “Unknown Eurasian lynx Lynx lynx: New findings on the species ecology and behaviour” by Vadim Sidorovich, Jan Gouwy and Irina Rotenko (2018) we described all the cases we registered until the winter of 2018-2019 and stated that the Eurasian lynx is clearly a more social carnivore than what is believed based on general views about solitary carnivores.
During the past winter of 2018-2019 we continued to gather information about sociality in lynxes by snowtracking and extensive camera-trapping with individual identification by fur spot pattern analysis in Naliboki Forest, north-western Belarus.
Before we report about the new information on such poorly known social contacts of the Eurasian lynx, obtained during the winter of 2018-2019 (after the publication of the book), we will first resume the cases described in the book.
Because our methodical approach soon revealed aspects of the life of lynxes which were completely unknown before, we wanted to share the main new findings and hypotheses earlier and decided to publish them in a pilot book.
After an introduction, description of the study areas, and methodology chapter, each chapter starts with a statement based on our findings, the statement is followed by a short literature review regarding the topic, an assumption on why the topic has not been studied yet, and finally our own data and information sources, among which many photo documentations.
