Chuffs and Bluffs

July 18, 2008 at 4:34 am 2 comments

From the USGS Northern Divide Grizzly Bear Project:

“A wolf feeds on a road-killed elk carcass in the morning. A grizzly bear with two cubs feeds on the carcass in the evening. A grizzly bear will chuff and pop its jaw when it feels threatened. Sometimes it will also charge at the threat, usually veering off or stopping short – a bluff charge. Early the next morning a grizzly bear with cubs chuffs and bluff charges a wolf. The wolf appears to be alone and, at times, postures as if it is playing. Video camera was triggered by a motion sensor.”

    1) That wolf is HUGE. Compare him to the full-grown sow griz mama bear.

    2) He ain’t playin’. I see genuine predatory intent towards the cubs. The cubs are very nervous, doing the meerkat scope and such, and they have reason to be.

    3) Just because two animals have a potential predator/prey relationship doesn’t mean there is no social relationship, interaction, or communication. Clearly not.
