American Black Bear (Ursus americanus)

American Black Bear

The American Black Bear is North America's smallest and most common species of bear. It is a generalist animal, being able to exploit numerous different habitats and foodstuffs.

Sows usually produce their first litter at the age of 3–5 years. Sows living in urban areas tend to get pregnant at younger ages. The breeding period usually occurs in the June-July period, though it can extend to August in the species' northern range. The breeding period lasts for 2–3 weeks. Sows tend to be short tempered with their mates after copulating. The gestation period lasts 235 days, and litters are usually born in late January to early February. Litters usually consist of 2 cubs, though litters of 6 have been recorded. At birth, cubs weigh 10–16 ounces, and measure 8 inches in length. They are born with fine, gray, downlike hair, and their hind quarters are underdeveloped. They typically open their eyes after 28–40 days, and begin walking after 5 weeks. Cubs are dependent on their mother's milk for 30 weeks, and will reach independence at 16–18 months. They reach sexual maturity at the age of three years, and attain their full growth at 5 years.
