Some time ago we saw bison residing in the Forestry District Trzcianka. In the place it turned out, the herd consists of 5 animals, cows, and probably wandered from the  Miroslawiec herd, which indicates that there had to be an internal split the group. This is the natural order of things, although bison are herd animals that live in a hierarchical society, there are between in living interaction. This is a very favorable situation, because it proves that the females can migrate away from the parent herd.
