Wildlife Photography: Roadkill 1 of 3

Road Kill
One of my research interest in is Road Ecology, mainly how roads affect wildlife mortality. One must look at roadkill in two differet categories: "(1) traffic, road, and landscape influences, and (2) species behavior and ecology" (Forman & Sperling 2003). I'm more curious of the latter. When I find roadkill, I ask: why was it on the road? Was it hunting on the road? Was using it as thermoregulation? Was it just crossing?
Timber Rattlesnake
Crotalus horridus
Tyler County Date: September 17, 2004
According to Janie Munoz's field notebook the locality data: "From Martin Dies Jr. SP we took US 190 W and went 3.4 miles South on FM 92 then traveled 12.3 miles and turned West on FM 1013 we then traveled another 3.2 miles and went North on FM 2992. Then we went 8.7 miles and turned west on FM 1716 until 7.1 miles later, we find a dead Timber Rattlesnake in the middle of the road." This species is listed as "threatened" by the state of Texas.
