Mammalia Martes foina foina, commonly known as the Beech Marten in English, is a medium-sized mustelid native to much of Europe and parts of Asia. In the Comunidad Valenciana, this species is locally referred to as "garduña."

The Beech Marten is distinguished by its slender body, bushy tail, and a characteristic throat patch which varies from white to pale yellow. Its fur is typically brown, providing an excellent camouflage in its natural habitat.

• Habitat: This species is quite adaptable, thriving in a variety of environments including forests, open countryside, and even human-altered landscapes such as villages and suburban areas in the Comunidad Valenciana.
• Diet: The diet of the Beech Marten is omnivorous and versatile, consisting of small mammals, birds, fruits, and occasionally insects. This dietary flexibility helps it to survive in various habitats.
• Behavior: Beech Martens are primarily nocturnal, spending their nights hunting and exploring. They are known for their agility and climbing skills.
• Reproduction: In the spring, typically between March and April, the Beech Marten gives birth to a litter of about 2 to 4 young after a gestation period of around 9 months which includes a delayed implantation phase.

In the Comunidad Valenciana, the Beech Marten plays an important ecological role as both a predator and scavenger, helping to maintain the balance of the local ecosystem.
