Occurrence Remarks: Biggest wild caught red rattlesnake ever. Bigger than Klaubers 162cm record by 7cm given our estimation. Had just eaten a rabbit. Homeowner requested removal but I was able to convince them to release it past the back yard fence into the open space. Found in lakeside.

Occurrence Remarks: Slaughtered by the neighbors out of ignorance before I could relocate. Last image was taken by the neighbor who decapitated the snake with a shovel. I talked with him after I arrived just a little bit too late to save the snake. Suspects address kept anonymous.

GBIFID: 4923608064; Occurrence Remarks: It was initially startled when I approached it from behind and touched it with a mechanical grabber which caused it to spin around, coil, rear up and rattle (I was too scared to photograph this) but it didnt strike that I could see...but it was so fast it may have done so as it spun around without me noticing. I placed brown paper on top of the snake to capm down. This apparently also calmed down the snake as when I checked it again, it had flattened out and did not react to further nudging. This was also around sunset, so it had also probably cooled down. At this point it was fairly easy to place a piece of cardboard as a ramp into a plastic box placed on its side and then push the coiled snake onto the ramp and pushed the whole ramp into the box. At which point I quickly plavef the lid over the box before the snake could unvoil itself and escape. I released it the next day on public land, where it went through a fence to an area people and pets typically cant access. Wins all around.;; Coordinate Uncertainty in Meters: 29039.00000.

It was a good rattler, and big enough for a squirrel or small rabbit, set up on a little game trail were it had shade and a confined narrowing of the trail. It was good because it gave me a proper warning to stop me in time. Just enough buzz to freeze my blood. If it hadnâ€™t warned me I would have been in there in that trap within inches of it and nowhere to go but ahead or back. But I had to move it because I had to go that way, so though it wasnâ€™t at all mad I had to make it mad so it would move. Really made me respect it the way it not only buzzed but began a long deep hissing as it moved away. Needless to say I stayed on the main trail the rest of the time out there.; Coordinate Uncertainty in Meters: 0.11000.

Del Dios Highlands. Instead of going up the trail I went up the powerline road. Very steep. Highly disturbed but still good plants in the chaparral. I took a side trail and came to a rocky outcrop. I thought it might be a good idea to watch out for snakes here, and sure enough, there they were. I saw only the tails, and at first it looked like just one snake. Then I could see that there were two tails, somewhat wrapped around each other. They might have been mating. They did not rattle at all, but just slowly moved away. I got my photos as they slithered off. I felt bad for disturbing them, but by the time I knew what was going on they were already disturbed.; Coordinate Uncertainty in Meters: 0.00000.

Sighted in Borrego Palm Canyon, First Grove (aka Palm Oasis) during monthly servicing of my bat acoustic detector in place since April 2019. This is the first snake of any kind encountered at this site in 50 visits. I have occasionally seen C. mitchellii lower in the canyon and up canyon in Fourth Grove. This Red Diamond did not rattle. I heard it scramble to avoid me as I approached from the creek bed and came within a meter or so of stepping on it. After a quiet photo session, I continued up to my recorder and it moved a few meters to a less exposed location at the base of a palm. It was still at that location when I departed.; Coordinate Uncertainty in Meters: 0.00000.
