Pine marten (scientific name: Martes martes) is a medium-sized carnivore, about the size of a domestic cat, with 8 subspecies.
Pine martens build nests in tree holes or shrubs. They are mainly active at night or dusk. Their claws can be semi-retracted, allowing them to live in trees. Tree holes are the preferred nesting site, and a family has several nests within the roosting range. In winter, the cold ambient temperature will abandon the tree nest and choose rock crevices as hiding places. Martens more frequently choose to roost underground.
Pine martens have a strong sense of territory, and mark their territory and range of activities with scent glands discharged from the abdomen and anus. Males will successfully defend their territory, and mating females also have a certain range of territories. The size of the family range varies greatly. Obviously, males have larger territories than females, and they will overlap with those of one or more females. However, the territories of males are usually non-overlapping. According to researchers' measurements, the average territory of males is 23 square kilometers, and that of females is 6.5 square kilometers. There are also estimates that male territories are only 2.2 square kilometers and female territories are 1.5 square kilometers. Seasonality has a strong influence on the range of most populations, with fall/winter ranges 8-54% smaller than spring/summer ranges. This range difference is also reflected in the distance covered by males at night, and ranges can overlap within high species densities.
Pine martens are omnivores, and the type of food they eat varies at different times of the year, depending on the seasonality of food sources. Diet composition and proportions often change according to season and local conditions. The breeding season is a unique de-ratification cycle for martens, when catches increase significantly, mainly voles. They have sharp teeth and eat small mammals, birds, insects, frogs, and carrion. In the fall, they eat strawberries, bird eggs, nuts, and honey. They are territorial and leave feces at their boundaries. Pine martens will chew plastic parts of vehicles to sharpen or clean their teeth.
Pine martens breed in February and March. The female gestation period is up to 7 months. Each litter has 1-5 pups. The pups weigh about 30 grams at birth and are blind and deaf. They can leave the nest completely independently at 6 months old. They reach sexual maturity at 2-3 years old. The life span of captive pine martens can reach 18 years old, while wild pine martens can only live to 8-10 years old.
