From my observations, young bears exhibit a mischievous behavior more often than adult bears. Chalk it up for play, curiosity, or too much energy–who knows why. This second year bear took a liking to the wood slats on the walkway to the bear viewing platform in Katmai National Park. Each year the park maintenance crew have some repair work to do from the various antics of bear chewing and non-malicious demolition. I scared it away once but it returned for more, so I grabbed a quick photo before deterring it again.
