SOOO @Lisa.Jok what you are really saying, is that you want to claim a record for a new species, the Clancy Stager, (maybe Homo dolus) but you want me or someone else to risk embarrassment by putting it out there?
My method is nothing fancy - I just carry a torch and look into hollows. This was cool to see, wish I got better pictures of the pups (only sliver seen in last uploaded photo), but once the mum saw me she blocked the entry.
