This 12 months we studied the query of wolf copy in Naliboki Forest within the space of about one thousand sq. kilometres. Within the spring of 2022, there have been current two breeding teams of wolves within the examine space: a pair and an grownup male with two pregnant females. All 5 grownup wolves had been recognisable, and we knew them from the earlier years.

First about copy of the three breeding wolves. Within the late March one of many females gave start in a burrow-den. Within the twentieth of April there have been a minimum of three pups along with her (we noticed them on the burrow entrance). One other feminine gave start within the late April on the space round 1.8 km from the den of the primary feminine, and within the mid-Could she had 4 pups of about 3 weeks previous in her burrow-den, which we investigated. The daddy wolf served for each breeding females. They visited denning space and dens of one another. All of the three wolves had been numerically registered strolling collectively in April and Could.

Plausibly the litter of the primary feminine was extirpated by lynx grownup male, which was registered visiting the burrow-den with pups. After this go to of the lynx, the mom wolf was not registered along with her pups anymore.

Within the beneath footage you will note making ready of a number of dens by pregnant feminine wolf and 4 pups of the three breeding wolves. A complete, a minimum of 34 such ready dens in sorts of both a burrow or a cavity or solely a pit there have been discovered within the denning space of those three breeders. You see the 4 pups in an outlier of badgers that was enlarged by the breeding wolves. The litter was inside this burrow 4-6 days.

Within the early June there have been alive solely two out of the 4 pups (see video beneath), which you might even see with the mom at one other burrow-den. In November solely one of many 4 pups was nonetheless alive.

The couple den was hidden in drainage canal financial institution that was coated by dense reed stand within the centre of an enormous meadow. Within the late Could the wolf household stayed inside forest habitats in a treefall. There have been 4 surprisingly large pups. Solely one in every of them was alive at first of November.
