La Ventana Stories

We are now approaching winter! Due to the recent cold weather here in LV/ES, most of the reptiles have retired into their winter abodes, like many of the human residents. One difference, however, is that the majority of the reptiles are underground. Today, we will dive deeper into the subterranean world where reptiles spend so much of their time, and shine a spotlight where the sun rarely reaches. The first questions we should ask ourselves are: where do all the tunnels come from, and who makes them? These questions have many answers, as there are a variety of interesting fauna giving rise to this underground kingdom.

Around here, many of the tunnels belong to the Desert Iguanas, not the big ones living on rooftops, but rather the smaller, sand-colored iguanas that prefer life on the ground. In the winter months, these characters are completely absent; come spring, however, they will emerge and become one of the most common lizards in the area!

Another set of important burrowers are the mammals, digging larger burrows. Once the squirrel, rabbit, mouse, skunk, etc. leave their burrows, those spaces become good hideouts for other creatures.

A third, often overlooked group of burrowers are the insects! Ant colonies create huge nests that become part of the tunnel web after the ants move on. Termites do this job as well, along with many other insects.

Now we know who made the tunnels, but who lives there? And what about the creatures that rarely leave the soil? To be continued next week! Chance Stevens chancestevens123@icloud.com

The Five-Toed Worm Lizard is a strange, unique and seldom found creature that spends most of its time underground. This species is native to the Baja California Peninsula. There is a good-sized population just outside of La Ventana, though not much research has been done on these two-legged lizards.

If you were to see one of these crazy creatures out in their natural habitat — which is Very Difficult — you would probably be confused. At first glance, you would think that it was a worm because it is pink and looks like it has segments, but then you would see its little two front legs and teeny tiny black eyes. Upon further inspection, you would see that it more closely resembles some sort of invertebrate over a lizard. 

Mexican Mole Lizards (another name for the same species) are not widespread, and seem to prefer loamy cactus forests. These lizards are so introverted that many people who live here their whole lives never see one! I was able to find one because of patience, perseverance and a very helpful shove in the right direction by my amazing friend, Prof. Bradford Hollingsworth, Curator of Herpetology at the San Diego Natural History Museum. 

Above the surface, mole lizards are a bit scattered and spend their time trying to dig back into the dirt; underground, however, they are fearsome bug hunters perfectly suited for their specialized life. If you do come across one of these enigmas of nature, photograph it and let me know where you found it, since it could be a new population! – chancestevens123@icloud.com

This week I am featuring La Ventana’s five most common snakes. There are around 15 snake species in our town, so many of the less common snakes are not covered in this column, but the snakes below account for about 80% of the questions I receive!

1. Baja California Coachwhip: These large, day-active snakes reach lengths of over six feet! They are extremely fast and come in an array of colors; around here, they are typically black. They are semi-arboreal, meaning they spend a good bit of time up in trees. They are completely harmless. Here are two photos of different colored coachwhips.

2. Cape Gopher Snake: Cape Gopher Snakes are large and beautiful snakes. They are particularly active during the shoulder seasons (spring and fall) and have incredible patterns. They are completely harmless.

3. Coast Night Snake: Coast Night Snakes are small, nocturnal snakes commonly found slithering around yards or underneath surface debris. These snakes are usually gray, and are commonly confused with rattlesnakes because they have vertical pupils. They, too, are harmless.

4. Western Patch-Nosed Snake: Western Patch-Nosed Snakes are quick, agile snakes that specialize in hunting whiptail lizards. These snakes have large eyes and crème and brown-ish black stripes. They spend a good bit of time with their heads down holes, as this is one of their best hunting methods. Once again, they are harmless.

5. Red Diamond Rattlesnake: Red Diamond Rattlesnakes are large, impressive and easily-identifiable snakes. They will usually support a large rattle, and often use it! These snakes are not really present in town anymore, but can be found just a bit up in the hills, including on mountain bike trails. They are dangerously venomous, and it is best to leave them their space.

We are now in early November and, recently, I have noticed a major spike in baby snakes and lizards. This means there are more reptiles than usual at this time, and we need to be very careful driving at night, because they are crossing the roads in abundance.

A few days ago, around 9pm, I heard a sudden exclamation outside, followed by “SNAKE! Snake!” Rushing out of my camper into our outdoor living area, I saw a small Cape Thread Snake (Rena boettgeri) slithering across the rug. I picked it up and started photographing it, then headed out to release it in a nearby bush. On the way to the bush, I noticed another small serpent on the ground, right in front of me!

Upon closer inspection, I concluded it was a hatchling Coast Night Snake (Hypsiglena ochrorhynchus). I picked it up, though now I was holding a night snake, a large spotlight, a phone for photography purposes, and an extremely squirmy thread snake. Clearly this was not sustainable, so I put the light down, just to discover that this left me in complete darkness. I picked the spotlight back up and, to my dismay, the thread snake squirmed out of my hand and right into a crevice inside the spotlight.

At this point I had no idea what was happening, so I called for backup. The night snake made a break for it, successfully escaped my grasp and slithered off into the brush. A friend arrived and started to assist me but, unfortunately, the thread snake was inside the back of the spotlight, rendering the light useless in finding the escape artist. Eventually we got another light and discovered the thread snake hiding behind the battery case, and it came out easily. I then tracked down the night snake, and eventually everything worked out fine.

This week, I will be covering the Cape Region’s third and final rattlesnake: the beautiful Lower California Rattlesnake (Crotalus enyo).

I was fortunate enough to come across two on my recent trip to Cerralvo. These gorgeous little rattlers are ambush predators, and spend most of their time in wait of prey. In my experience, they are quite docile and will remain still to avoid detection before slithering off into the brush. They are not as large as other rattlesnakes in the area, and typically less common as well. 

Interestingly, these rattlesnakes don’t just eat the typical array of rodents and lizards; they are also well known to eat centipedes! Rattlesnakes have quite a reputation and, although they are dangerous, I am personally much more worried about their venomous centipede prey! 

Unfortunately, upon discovering rattlesnakes, a common reaction is for people to promptly kill them out of fear. Sometimes they are relocated, yet very rarely are they just left to just go about their business. Although relocating a snake is much better than the alternative, rattlesnakes are very important to the ecosystem, and we don’t really have many of them left in LV/ES proper anymore. 

Here are a few reasons rattlesnakes are good neighbors:

1. Pest control: rattlesnakes are especially successful at hunting rodents.
2. Rattlesnakes keep to themselves; it is actually quite difficult to find rattlesnakes even where they are common.
3. They sleep through the winter months; from December to March rattlesnakes are mostly underground.
4. They won’t stop by uninvited or, if they do, you won’t have to worry about serving them beverages and small talk.

November Reptile Walks! Come join us to find reptiles! This Friday, November 3rd, and Sunday, November 12th, from 9-11am we will be hiking Punta Gorda in search of serpentine friends. It will be a fun, educational event, although we are not guaranteed to find anything. Meet at the Punta Gorda Trailhead on the far north end of town. chancestevens123@icloud.com
