Observation notes: These were in a wind cave very strange as we always thought they were seeking shelter, fairly sure they were all males. Anyway they were on closer examination using there proboscis to sip minerals like the salt they also liked from my hand. They were very calm and approachable even to the point of climbing onto my finger this is for Jeffery Ha Ha all in fun as this in the index finger! Yes salt from eating pumpkin seeds or other salty food is the only attractant is very helpful as they like salt? Windy cool for this time of year wind 15 with gusts higher clear mostly some drizzle in mountains. Also a peak at the patterns of the topside its worth looking at when they cooperate! Not sure we saw any females probably not as all were this size an female's are quite a bit larger!
