This was one crazy bird (a Western Capercaillie). Spring is mating season, and this guy wanted everyone away from his territory so he could attract a lady with his song. The fact that I'm over ten times his size and carries a metal club (tripod) didn't stop him from advancing on me and making a threat display. Then again, I did back away - so maybe I was dealing with a master of strategy.
