The general body shape is long and slender. The marten is an opportunistic feeder that eats primarily small mammals including squirrels and rodents. Occasionally birds, fruit, nuts, insects, and carrion will be eaten as well. The main killing technique consists of a quick, powerful bite to the back of the neck. Reproduction The breeding season occurs from June to August.
Mates find each other by means of strong scent marks left by anal glands.
After mating fertilization of the eggs is delayed and does not take place until February. The embryos then develop within a month's time. They are weaned after 42 days and full size is reached very quickly, around 3 and a half months after birth. Behavior The marten is usually solitary and nocturnal, but on occasions they have been observed in pairs. They often hunt during the day when prey is abundant.
