when do bears sleep?

Question

i know they hibernate all winter, but what happens the rest of the year, do they take naps or anything? if so do they sleep in the night time or day?..thanks.

Answer 1

I was reading about kodiak bears the other day, I have several books on bears. Kodiak bears den up in late October. They usually emerge in about April depending on the weather ofcourse. Brown bears are more active at night than they are during the day, but they do like you said nap, though napping is daytime napping, not night time napping. They spend as much time eating as they can. American black bears are slightly different than their grizzly cousins with dawn and dusk seeing the most activity and any sleeping is more likely at night than during the day. Polar bears I am not too sure about but there is the whole 6 months of daylight and 6 months of darkness to consider there so just whenever they are tired I suppose whether it is technically day or night.

Answer 2

During sumer month's bears that go into winter torpor (bears do not actually hibernate) must feed about twenty hours a day in order to gain enough fat reserves to make it through winter. That leaves only four hours to sleep and do whatever. This varies of course with coastal bears that feed on salmon being able to get by with feeding fewer hours (salmon supply a relatively abundant high protein high calorie food). Sleep can be anytime but is more likely during the day. In the southern states black bears spend much less time than this feeding because they do not go into long winter torpors.

BTW Torpor is a lighter sleep than true hibernation. In true hibernation the body temp is dropped to the surrounding temperature. Large animals can not hibernate because they can not store enough fat in order to raise their entire body back up to working temperature if they drop their temperature that low. Therefore bears go into torpor. A researcher found this out about 20 years ago by taking the temperature of 'hibernating' grizzlies in Alaska. Apparently he was quite surprised by this, at least according to his journal. That was the only thing that was found of him.

Answer 3

They sleep during the day or night. contrary to popular belief they do not hibernate all winter. Have seen a lot of them while cross-country skiing in Alaska.

Answer 4

I have only seen them awake once at the zoo!

I think they sleep at night and nap during the day

Answer 5

Of course they do. I have a lazy grizzly bear of my own in Yellow Stone National Park who sleeps a lot and during the day time he hangs out with his friends drinking beer, stolen from the people who go for a picnic in those areas.
Ha....Ha.....Ha..!!!!!!
