When approaching a bear, remain calm, talk in a normal voice, wave your arms, and keep your distance. Alternatively, you can use pepper spray if you’re close enough to avoid provoking the bear. Lastly, bears are not aggressive unless you approach them. They may simply be trying to get a better view of you. Another interesting fact about bears is that they have a varying gestation period. A mother bear can be pregnant for up to 150 days, but a female may not be ready for a litter. In addition, bears can experience “embryonic diapause,” in which the embryo stops developing until it implants in the uterine wall. If a bear is pregnant, the gestation period will be anywhere from 108 to 140 days, though the exact number depends on various environmental factors.

Apart from colour vision, bears can recognize movement and other objects. They have superior navigation skills and excellent memory. Their large brain to body ratio helps them to use tools effectively. They are particularly adept at detecting movement and other sounds. They also have great senses of sight, and can smell ripe fruits. So if you see a bear during the night, you’ll know if it’s close to you or not. And last but not least, bears are very protective.

The main threats to bears include habitat loss and human-wildlife conflict. Humans have been responsible for creating these issues, and habitat loss is one of the leading causes. Bears are forced to seek out fewer food sources in urban areas. During periods when food sources are plentiful, many bears are killed for their human safety. But, in many cases, these conflicts with bears arise as a result of mismanagement of human food and garbage.

A bear’s hibernation allows it to recycle waste products and heal from injuries. Hibernation allows a bear to conserve energy during the colder months, allowing it to recover from its winter hibernation. A bear’s body temperature can reach up to 50 degrees Fahrenheit. A bear’s hibernation schedule is influenced by temperature fluctuations, but a bear’s temperature may also influence its decision to emerge from hibernation.
