Species card
Martes foina · Erxleben, 1777
The most common predator around human settlements in Poland. A master of adaptation — it will fare just as well in the attic of a villa near Warsaw, in the ruins of a farm in Masuria, or under the roof of a village church in Lesser Poland. Active at night, exceptionally quiet, it leaves behind a characteristic set of tracks — and many questions from the homeowner.
The beech marten doesn't choose an attic by accident — it looks for warmth, silence, and a safe route. A human home meets all three conditions.

A dog awakened in the middle of the night, a short scuffle by a woodpile, a drop of blood on the muzzle in the morning, and a swollen lymph node. The most common question that later reaches the veterinarian's office is: …
