..Pine marten (Martes martes) A stealthy forest species named after the golden spot on the underside of its neck. It used to be relentlessly hunted because its fur was highly valued and served as a means of payment, hence the name for today’s Croatian currency, the kuna (the animal is called kuna zlatica in Croatian). This small, slender and agile animal is a predator which feeds mostly on small mammals, birds and bird eggs. It lives in the treetops and is very difficult to sight, unlike its relative, the white marten, which can often be found near people..
