If you missed our Grizzly Encounters live chat with wildlife expert Peter Gros, former host of Mutual of Omaha's Wild Kingdom, we've got the transcript with your grizzly questions answered, right here.

Peter Gros: What a thrill to see the grizzly bears of Alaska again. I had the pleasure of visiting them on Admiralty Island years ago as well as inland on their mainland feeding ranges. You have all had the priviledge of seeing the most spectacular bear footage I have seen to date.

corysmistress: Do the bears sleep the whole winter through without getting out of their dens?
Peter Gros: Generally bears will hibernate the entire winter. They are the only animal able to survive half a year or more without eating, drinking or defecating. Their energy is supplied mainly from stored fat reserves. The fatter the bear at the onset of hibernation, the less lean body mass it burns during the winter. Fluids and amino acids are derived by recylcing products that are normally discreted as urine. Bone does not deteriorate despite inactivity. This process is so efficient that bears rarely die in dens. So it is very rare for a bear to leave its den during hibernation.
