Sound up! Ever hear a bull elk hiss? It’s not something you hear very often. Bulls will hiss when they’re irritated or warning off another elk, especially during the rut when everyone’s a little fired up. It’s their way of saying, ‘Give me some space.’ Such a cool thing to witness. This was last weekend. #estespark #elk #bull #rut #wildlife #wildlifephotography #foryoupageシ #videoreelsシ #colorado | Colorado Wild Photography
