Bear News and Research

Alex Wierbinski's picture

By Alex Wierbinski - Posted on 12 February 2017


The repository of Bear news, research, and stories we come across.

I've written about my experiences with High Sierra Black Bear Behavior in the Trail and Camp Skills section of the Trail Guide. Remember, bears act differently in different locations, and can be quite unpredictable in most situations.

Most times we can figure out what they want, and that typically boils down to two things: Food, and/or to be "left alone." Bears have personalities and feelings, which make them almost as unpredictable as that most deadly of beasts, humans. Almost...

 Suburban Bear Attack:

Florida: Bear attacks woman, Dec 4, 2013.
“In March 2011, Kumar said she called FWC when a bear tried to drag the entire freezer out of her garage.”

“and found an unleashed dog was present in more than half the encounters.”

"But dogs can excite and provoke bears to the point where a bear attacks not only the dog but the person accompanying the dog as well. Quite a number of dogs were killed."

2 days Later:
Bear hunt: Florida officials search for animal that mauled woman's face, CNN, Dec 4.

1 day Later:
Bear suspected in attack captured, killed, CNN, Dec 5, 2013.
 These things always end badly for the bear. My solution is quite simple: Mandatory bear proof garbage cans for all home and business in bear territory. No Food-No Bears. With no bears dog walkers will be safer.

The thing between dogs and bears is crazy. They seriously do not like each other.
