This pair of Amazonian hog-nosed vipers lay quietly at trailedge.
Have you ever while herping, stopped dead in your tracks thinking that you just walked by something you should have seen but you weren’t sure just what it was? I’ve done that a couple of times with copperheads and in no case do I know what it was that alerted me.

So knowing that I am fully capable of occasional oversights, whenever I have that feeling I stop and spend considerable time ascertaining what it was that caused that feeling.

I was on a forest darkened Amazonian trail and I had just stopped. Something wasn’t quite right. Undergrowth was sparse but fallen leaves of primary canopy, now variously hued in browns, yellows, and russets, littered the forest floor.

I studied the trail edges on both sides. Nothing. I walked back a few feet and studied anew. Nothing. I pulled out a pocket flashlight and restudied. Still nothing. I had just about decided that I had responded to a false alarm when not 12 inches from my foot a brown and russet leaf moved. No. It wasn’t a leaf. It was a snake. Wrong again. It was 2 snakes. Half hidden in leaf litter was a pair of Amazonian hog-nosed vipers! Not big, not bright, but a spectacular find.
