I didn't get close enough to ask! Eastern cottonmouths (Agkistrodon piscivorus) are one of the wildlife species I see frequently at Back Bay National Wildlife Refuge. Luckily always from a safe distance. I often see them swimming in the impoundments, hunting for fish and frogs along the edges. This individual was crossing from the marsh on the Back Bay side to one of the water impoundments not far from the visitor's center. I'll be posting some more images from Back Bay soon. If you are ever in the Virginia Beach area, I highly recommend visiting. I always have great luck with wildlife there and the sunsets can be spectacular (including the header for this blog). Enjoy your weekend!
