The American black bear is a mammal in the bear family, Ursidae[5]. NatureServe ranks it Secure around the world[2], and it is native in 42 US states and territories[3].
Conservation status
The American black bear is not listed as endangered or threatened under the US Endangered Species Act[1]. NatureServe gives it a G5 rank, which means Secure across its whole range[2], and an N5 rank, also Secure, for the United States as a whole[6]. The IUCN Red List category recorded by NatureServe is Least concern[7]. It is also on CITES Appendix II, which puts controls on trade between countries[8].
Where American Black Bear lives
NatureServe lists the black bear as native in 42 US states and territories, from Alaska and Washington to Maine and Florida[3]. It is ranked as extirpated or possibly extirpated, meaning gone or likely gone, in the District of Columbia, Delaware, Iowa, Illinois, Indiana, Kansas, Nebraska and Rhode Island[10]. NatureServe notes that numbers have gone up in recent years in the northeastern US[11]. The states with the most GBIF sighting reports are California, Alaska, North Carolina, New York and Wyoming, which reflects where people look and report[12].

Habitat
Black bears live in hardwood, conifer and mixed forests and woodlands, in forested wetlands, and along rivers and creeks[14]. They do best in forests that mix leafy trees with conifers and have thick plant growth near the ground, though they can turn up in other settings too[15]. When resting, a bear uses a den such as a hollow log, a hole in a tree, a cave-like spot underground, or a patch of dense cover on the ground[15]. Young bears are born in a den[15].

Size, diet and lifespan
The black bear is an omnivore, which means it eats both plants and animals, including fruit, insects, dead animals and garbage[16]. One estimate puts its diet at 50% fruit, 30% other plant material, 10% warm-blooded animals and 10% fish[17]. A typical bear is about 160 cm (63 in) long[18] and weighs about 200 kg (441 lb)[19]. Young are born in January or February and stay with their mother until the fall of their second year, with 1 to 5 young in a litter[20] and 2 as a typical number[21]. The longest recorded lifespan is 34 years, for a bear in captivity[4].

When to look for it
In winter black bears go dormant in their dens, a deep rest that is not true hibernation[27]. They do not migrate[26]. Bears can be nocturnal, meaning active at night, or crepuscular, meaning active at dawn and dusk[28]. They mate in June and July[20], and GBIF sighting reports peak in June, July and August[29].

Safety around this animal
These tips are quoted in summary from official agencies. We add no advice of our own. Follow local rules and the agency pages linked below.
From National Park Service
- Stay calm and talk to the bear in a calm voice. Stand still and slowly wave your arms so it can tell you are a person.
- If a bear follows you, stop and hold your ground. Do not run, and do not climb a tree, because both black bears and grizzly bears can climb.
- If a grizzly or brown bear attacks, leave your pack on, lie flat on your stomach with your hands clasped behind your neck and play dead. Fight back only if the attack keeps going.
- If a black bear attacks, do not play dead. Get into a car or building if you can, otherwise fight back, aiming at the face and muzzle.
- Never let a bear get your food. A bear that gets food keeps coming back, which makes it dangerous for the next visitors.
- Carry an EPA-approved bear spray made to stop aggressive bears. It is a deterrent, not a repellent, so never spray it on yourself or your gear.
From National Park Service (Yellowstone)
- In Yellowstone, the National Park Service asks visitors to stay at least 100 yards (91 m) from bears, wolves and cougars.
- If the animal moves closer, back away. Approaching wildlife close enough to disturb or displace it is illegal in the park.
- Never feed wildlife. Use binoculars or a long camera lens instead of moving closer.
