Large male Saurmalus ater was observed, head bobbing (seven times) on a large boulder over looking a valley. The head bobbing stop when I start to move closer to this S. alter to be able to take more close up pictures.
Two juveniles S. aters have been observe with in 40 feet of where this picture was been taking. (One was observed the same day 3/23/2014. The second was observe on 4/28/2014. No photo vouchers where taking of this Juveniles S. aters).
Observed species 3/23/2014 -
1.) Three Sauromalus ater (Photo vouchers where taking).
2.) Seven Aspidoscelis tigris Where observed among the rock hill side. A. tigris where chasing each other in groups of two, observation of A. tigris interacting with groups of two seem to be preoccupied in chasing (at a faster pace that there average walking speed) each other and not paying to much attention to there surroundings. This ethology anadoltole observation seem to be indicated by been able to observe a pair chasing each other for serial minutes. Until one of the pair of A. tigris would observe me and sundial the pair would stop and start to walk off. after a few seconds of walking off. One of the two A. tigris would start to pursue the other and the chasing would start again at a great distance, than original observed at. One was observed by it self . (No photo vouchers where taking).
Anadotole evidence obtain from observing of a posted picture from facebook shows a Lichanura trivirgata taking from this area within the same weeks of when this photo vouchers was taking 3/23/14.
(It should be noted that I did not look under any rocks or plywoods that day).
Habitat photo has been had to this profile of the area.
