 A week or so ago Zach started a thread on this same topic, also without getting much anywhere

I've been pondering if there is a statistical means (pun intended!) of coming up with a population estimate; perhaps some modification to a biological mark-recapture method  
METHODS OF ESTIMATING POPULATION SIZE -- MARK-RECAPTURE
