Dusky Pygmy Rattlesnake (Sistrurus miliarius barbouri)
It took me three trips to the Everglades to find a snake, which is a pretty miserable track record. In my defense, all three trips were at the end of the year, not high snake season due to the relatively cool temperatures. This little charmer was coiled up a few feet from the trail around Eco-Pond, hoping nobody would notice it. Almost nobody did.

Dusky Pygmy Rattlesnake (Sistrurus miliarius barbouri)
I had the privilege of herping in Lake Woodruff NWR this afternoon with professors Peter May and Terry Farrell and a few of their students. Lake Woodruff features many frogs, alligators, turtles, etc, but the highlight would have to be the beautiful and plentiful Pygmy Rattlesnakes. The recent flooding of much of the snake habitat slowed us down a little, but we slogged through the 18-inch-deep water and eventually found 7 or 8 of these tiny rattlers perched in palm fronds and other vegetation a foot or two above the water level. This one is probably about a year old, according to Dr. May.

Dusky Pygmy Rattlesnake (Sistrurus miliarius barbouri)
This charming serpent was crossing the trail between the campground and the popular springs. When it completed its crossing, it coiled up next to the nearest tree.
