Eurasian beaver
The Eurasian beaver disappeared from
Białowieża in the mid-19th century due
to hunting. It was reintroduced in 1956.
Today, they live all along the rivers,
streams, and ponds throughout the forest.Noctule bat
Noctule bats nest in
hollow trees. The holes
must be high enough to
avoid predators such as
pine martens. Noctules
are one of the first bats
to come out at night,
and hunt moths and
flying ants.Old-growth forests have
plenty of standing dead
trees as well as live ones.
Woodpecker nests or holes
where the tree has rotted
make ideal bat roosts.Red deer Red deer find
leaves, small twigs, and bark
to eat in the fall and winter,
and herbs and grasses during
the summer.
European bison The bison
is Europe’s largest land
mammal. There are around
900 in Białowieża forest.Great spotted woodpecker
Woodpeckers nest in holes
made in tree trunks. They
search for tasty insect prey
in the bark.Tawny owl This woodland
owl hunts at night for birds,
rodents, amphibians such as
frogs, and bats to eat.Yellow-necked mouse
This mouse prefers living in
woodland, because it eats a
lot of tree seeds. It is also an
excellent tree climber!Eurasian red squirrel
Eurasian red squirrels like
to eat seeds, especially from
conifer trees.Eurasian badger Badgers
are common in forests. In
addition to plenty of worms
to eat, they find lots of hollow
trees, which they use as
daytime shelters.Location
