Countdown to Snake Count: 3…

By far the most commonly seen snakes at Muleshoe headquarters, and most places where they live, are western diamond-backed rattlesnakes (Crotalus atrox, hereafter diamondbacks). They are wide-ranging, found in a variety of habitats, and eat pretty much anything that fits in their mouth. They also don’t seem to mind humans moving into their space; several at Muleshoe spend most of their active season at headquarters and of course there’s that group that over-winters under one of the buildings at headquarters:

Diamondback behavior at dens is quite different than Arizona black behavior we discuss at SocialSnakes. While most rattlesnakes in Arizona breed in the monsoon season only, diamondbacks also breed in the spring. So you can often see courtship and combat right at their dens!

We didn’t see anything like that at the headquarters den this year, but next year we’ll be ready with timelapse cameras to catch any action.

Unfortunately for diamondbacks, not all human neighbors are as accommodating as we are at Muleshoe. Often when diamondbacks show up in a human’s yard (or from the snake’s perspective, humans show up in their territory), they are killed or translocated (moved). Translocation may seem like the humane choice, but Snake Count attendees will learn on Saturday why that may not be the case. As always, prevention is the best cure. Check out this brochure from the Tucson Herpetological Society on how to make your yard less snake-friendly (if you don’t want snakes there).

We like our yard snake-friendly 🙂

Sadly diamondbacks are also the rattlesnake most commonly collected for rattlesnake roundups. We have written a little about roundups before and a show that glorifies them. Frankly it’s too upsetting for me to say much, so I’ll refer you to Rise Against Rattlesnake Roundups if you wish to learn more about these horrific events and what you can do to stop them.

Now to end on a more positive note, here’s my favorite diamondback of all time, looking stunning. We haven’t seen Henry in a while, maybe he’ll show up for Snake Count – will you?
