Back at Rocky Mountain Arsenal and yet again the Bison herd were not cooperating. The were way too far away. I sat and watched for about  three hours, watching their behavior. The bulls were definitely in rut mode. Sniffing potential mates. Wallowing in the dirt. Though none actually battled yet. Rut is here but not in full swing yet. Well since that was a bust. Only thing left to do was to see what Mule/White-tails I could photograph. It turned out to be another successful morning. I was even able to get some videos. Which may end up in my 2018 Wildlife Highlight video (watch 2017 here).
