It is with a heavy heart that I report the death of one of our snakes, Chris (male Arizona black rattlesnake). While I love all of the rattlesnakes at Muleshoe, Chris has a special place in my heart because he was the first Arizona black rattlesnake I found here (from The Arizona black rattlesnakes trickle… Read More


OK, I (melissa) am the only one who has been gone, but that meant no blog updates.  I’ve spent the last month finishing up fieldwork at our other project in central Arizona. And my how things changed at Muleshoe while I was gone! When I left, snakes were just starting to come out; now things… Read More


So in our last post there was one rattlesnake left that was still in his den as of 30 March. I checked on that snake this morning and am happy to report that Chris (male Arizona black rattlesnake) has emerged! He has not yet moved away from his den site, but was getting some sun… Read More


December and January were pretty quiet here at the ranch; as you can see from the above photo, the weather has not exactly been snakey. OK, it only snowed a couple times and melted pretty quickly, but it has still been too cold for snake activity. Even Jaydin (adult male black-tailed rattlesnake) finally settled into… Read More

The week began with a visit from our dear friend Roger Repp, who wanted to check out our new study site and track some of the snakes. We had barely started our hike down Hot Springs Wash when we came across a very healthy looking Sonoran whipsnake (Coluber bilineatus). As is typical with this species,… Read More


A Sonoran whipsnake (Coluber bilineatus) at Muleshoe Ranch. Our first week of tracking was pretty uneventful.  We release snakes as soon as possible after their transmitter implantation surgery so that they can recover in their habitat. So typically the first week or so is pretty slow; the snakes lay low while recovering and don’t make… Read More


One week to go and we haven’t found any Arizona black rattlesnakes yet (remember, we wanted six). The clock is ticking. On the afternoon of 26 September, I started my snake search by checking on the bird-eater. He was in his usual spot, waiting for a thirsty bird. I then hiked downstream in hot springs… Read More
