Bigfoot drummer??

While continuing going through old audio files, I came across an incident that had me shake my head in disbelief.  Something appears to be beating on a plastic tub or bucket in the woods near one of my drop box recorders.  Before and after you hear something approach and walk away (Extended version) while no human speech is heard in the process.  Can I say it was a Bigfoot?  Nope, can't say that, it's posted here because of the fact it did happen in a well known and highly active research area.
