What on earth is that noise?  We pulled into camp and had just settled in when I first noticed it, repeated short bursts at a high frequency…. the kind that makes your fillings hurt.  I searched for animal or mechanical sources.  Geez, what is it?  Oh my gosh, we in the middle of a prairie dog colony and that noise is the mama prairie dog calling to her many young ones who are out and about.  So long to the cute little bark we have heard from other colonies when they are just chilling out.  This sound comes awfully close to getting them off my “aren’t they cute” list.  They are still fun to watch but that’s one more place we won’t be building our cabin, among prairie dogs!
