Here are a few more hints:
I encountered this Bobcat (Lynx rufus) walking along the side of the road today. When it noticed me it started heading into the dunes. This next photo makes me think it wasn't too happy to be disturbed during its midday stroll.
I'm not sure how consistent Bobcat fur patterns are. I looked back at the pictures from June 2012, but couldn't tell if this might be the same individual. What do you think?
