This post gives the documentation by a camera-trap of two different litters (10 pups altogether), two breeding females of the same wolf pack, the founding male and two pup-sitters in Naliboki Forest. The last feature is particularly essential. One or two pup-sitters were present at pups on about 60% of the hundreds of photos taken. It looks like we have registered the features of another trend in the wolf denning behavior that we haven’t faced with before the lynx got common. That is when breeding wolves use pup-sitters to save their pups from the lynx aggression (see another post for other details), when they go for hunting.
Mating in Eurasian lynxes and other questions in relation to that (such as pre-mating activity; life of kits, when their mothers go for mating; others) are quite poor investigated (e.g. Schmidt et al., 1997; Schmidt, 1999; Jędrzejewski et al., 2002; Breitenmoser-Würsten et al., 2007; Samelius et al., 2012). The scarce information published on the question shows that these complicated mating-related actions in Eurasian lynxes are too simplified, while researchers mention about mating in lynxes. Let’s say there is evident gaps in the lynx-related literature on the species mating.
Together with Irina Rotenko we published a book about wolves in Belarus. There, we will address the questions of the species reproduction biology that are still insufficiently investigated and full of contradicting hypotheses and knowledge. However, the main thing for us in doing this book is that being interested in studying these hidden part of wolf life, we would like to share the knowledge and skills we have gained on wolves in Belarus with wolf colleagues and amateurs.

I would like to share our knowledge on the early denning behaviour and raising pups after weaning in wolves basing on the information that was gained in Belarus mostly in Naliboki Forest and Paazierre Forest.
The information is divided into two items: the first item is early denning behaviour in wolves; and the second one is raising of pups after weaning.
Lynxes are known as mainly solitary carnivores. Social contacts between adults are believed to be strictly limited to a mating season and within mother-kits family group. Continue reading “Social behaviour in lynxes in non-mating season”
The common belief of the lynx-related zoologists is that parturition in lynxes takes place in a thicket somewhere under treefall. Sometimes, it really happens. However, during twenty years of searching for wolf dens in Paazierre Forest and Naliboki Forest in Belarus in April-June in 1997-2017 I have found more than one thousand of wolf dens (mostly without pups, former ones etc) under treefalls and other vegetation thickets (mainly young spruce ones), but only a few lynx denning sites (easily recognisable by presence of lynx hair) have been found under treefalls.

Concerning competition between wolves and lynxes in Belarus, it is worthwhile to compare the situation in the local wolf population in Naliboki Forest in 2008-2012 (when there were half as many lynxes as there are now) and in 2015-2017 (when there were about 50 and even more lynxes). Both wolves and lynxes were more or less protected in Naliboki Forest in the 2000s.
