Black Bear Behavior &Black Bear Senses
While bears may defend a food resource or mate while they are present, bears are not territorial. They do not patrol or defend a specific area from intrusion by other bears. Bears respect a certain personal space, but often several animals overlap each other’s living space at different times. A bear’s living space that provides food, water, and adequate cover is called a “home range.”
The size of a home range may vary each season and year depending on food availability, the bear’s sex or age, the reproductive status of the bear, and even the density of the area’s bear population. During major droughts and famine, bears will range much further than normal to search for food. Bears are excellent swimmers and will frequent nearby islands during seasonal and climatic changes.
In Florida, average annual adult home ranges for bears are 50 to 120 square miles for males, and 10 to 25 square miles for females.
Bears have the ability to navigate homeward from unfamiliar areas, which often brings them across dangerous roads. Learn more at our bears and roads page.
Black Bear Senses
Vision: Black bears are believed to see in color and have great up close eyesight. Recent research is showing that their long distance eyesight is not very good, they are likely not able to see details of a large objects from further than 30 yards away.
Hearing: They have acute hearing that is about twice as sensitive as humans and over a large frequency range as well. Bears often hear humans before we see them. Because of this, black bears will often move away before they are noticed.
Smell: A bear’s strongest sense is smell. They can pick up a scent from over a mile away! That is more than seven times better than a bloodhound. Bears, as a Family, are considered to have the best sense of smell of any land mammal. Their rumored poor vision may be due to their reliance on their sense of smell.
