How many babies does a Black-tailed jackrabbit have at once? (litter size)

How many baby Black-tailed jackrabbits are in a litter?

A Black-tailed jackrabbit (Lepus californicus) usually gives birth to around 2 babies.With 4 litters per year, that sums up to a yearly offspring of 8 babies.

Each of those little ones spend around 41 days as a fetus before they are released into the wild. Upon birth, they weight 84 grams (0.19 lbs) and measure 14 cm (0′ 6″). They are a member of the Leporidae family (genus: Lepus). An adult Black-tailed jackrabbit grows up to a size of 48.4 cm (1′ 8″).

To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.

The black-tailed jackrabbit (Lepus californicus), also known as the American desert hare, is a common hare of the western United States and Mexico, where it is found at elevations from sea level up to 10,000 ft (3,000 m). Reaching a length around 2 ft (61 cm), and a weight from 3 to 6 lb (1.4 to 2.7 kg), the black-tailed jackrabbit is the one of the largest North American hares. Black-tailed jackrabbits occupy mixed shrub-grassland terrains. Their breeding depends on the location; it typically peaks in spring, but may continue all year round in warm climates. Young are born fully furred with eyes open; they are well camouflaged and are mobile within minutes of birth, thus females do not protect or even stay with the young except during nursing. The average litter size is around four, but may be as low as two and as high as seven in warm regions.The black-tailed jackrabbit does not migrate or hibernate during winter and uses the same habitat of 0.4 to 1.2 mi2 (1–3 km2) year-round. Its diet is composed of various shrubs, small trees, grasses, and forbs. Shrubs generally comprise the bulk of fall and winter diets, while grasses and forbs are used in spring and early summer, but the pattern and plant species vary with climate. The black-tailed jackrabbit is an important prey species for raptors and carnivorous mammals, such as eagles, hawks, owls, coyotes, foxes, and wild cats. The hares host many ectoparasites including fleas, ticks, lice, and mites; for this reason, hunters often avoid collecting them.
