La Ventana Stories

Mobula Munkiana

It is that time of the year again! Every spring we have a very special gathering in our front yard: thousands of rays aggregate in a breathtaking spectacle. They are Munk´s pygmy devil ray or Mobula munkiana, locals know them as “tortillas”, because the sound they make when jumping out of the water, reminds the clapping of hands produced while making tortillas.

They are cartilaginous fish, related to sharks, and they inhabit the Eastern Pacific Ocean, from Mexico to Peru. They reach a maximum disc length of 4.2 ft (130 cm), with an average of 3 ft (100cm). They are filter feeders, and they follow the zooplankton blooms, moving around the Baja peninsula with them. This time of the year, they can be seen in our area, when the conditions are ideal for feeding and reproduction. All around the bay, they can be seen swimming gracefully in the water, hundreds of them together, moving their fins like birds flying, it is truly nature´s wonder. But they can also be seen out of the water: moving their wings and gaining enough momentum to propel themselves in acrobatic jumps, sometimes many of them at the same time. Nobody knows exactly why they jump, there are different theories, but I like thinking it is just pure joy.

For years they were fished till they were put in severe danger of extinction. They are very sensitive to overfishing because they have slow reproductive strategies, like many other cartilaginous fishes. They are aplacental viviparous and they only give birth to one pup, after a gestation period of 12 months, so it takes them a long time to recover after the removal of many individuals. Now they are protected, and we have seen increasing numbers, but they are still listed as vulnerable in the IUCN Red List. One of their main threats is bycatch from coastal fishing nets. Swimming with them is a great attraction for ecotourism, making them way more valuable alive than dead and favoring conservation efforts.

Red Diamond Rattlesnakes

Red Diamond Rattlesnakes (Crotalus ruber) are beautiful, large and amazing snakes. They are quite common right now, crossing roads and paths all over Baja. It is April and the snake season has truly begun! 

If you are a mountain biker or runner, or find yourself driving on dirt roads through the desert, you probably have already seen some kind of snake this year. Spring is generally the best time to see snakes, and we are in the middle of it! It is still relatively chilly at night, forcing many of the larger snakes to move around during the day, including rattlesnakes, gopher snakes, rat snakes, king snakes and even rosy boas! Strictly day-active snakes are also common right now, including patch-nosed snakes, whipsnakes and ever-present coachwhips (the big black snakes found all over La Ventana).

Of all of the snakes here, the only dangerous ones are the rattlesnakes. REPEAT: The only dangerous snakes in La Ventana are the rattlesnakes.  

We have three species of rattlesnakes in the Cape Region of Baja, but this column is about the Red Diamond Rattler. These gorgeous snakes are quite happy to be left alone and, in many cases, will just slither away. If they feel theatrical, however, they may rear up and rattle their tails. In that case, they will bite if you get too close. Keep in mind that rattlesnakes don’t want to bite you, because venom takes a lot of energy to produce, and they don’t get any benefit from biting you. Their venom is best used for catching mice. Rattlesnakes may move forward a bit when in their coil, but they will practically never chase you. If you just give them their space, then they will eventually stop rattling, and go back to whatever they were doing.

In the extremely rare case that a rattlesnake bites, this is what you should do: STAY CALM and try to call for help, and go to the nearest hospital with anti-venom, as quickly as possible. For La Ventana residents, the closest hospital with anti-venom is in La Paz.

There is confusion and a lot of misleading information about what to do, including sucking out the venom or cutting out the bitten area. Those are very bad ideas, and I would suggest not trying them.

The Cabalerra de Cerralvo (Part 2)

Part 1 ended with Daphne’s recollection of the aftermath of the earthquake… “The next morning, we launched on a tide flowing out of the Gulf toward the Cape. As it carried us back to Delicias, we drifted farther away from land. I screamed at Dana to pull harder, but the current’s grip on us overcame our efforts to paddle to shore, and it began to take us into the dreaded Cerralvo Channel and out to sea.”

Part 2

“I was ready to abandon our life-saving water cargo and swim for the beach, but after praying for help, another current pulled us back, and we beached the boat. Once we arrived, only force-feeding our prostrate burros and horses with a mixture of water, cornmeal, and panocha, a coarse-grain sugar, revived them.”

Sierra de La Laguna: Part 3 of 3

Wait! Which way to go? There were many paths traversing the valley, but which one led back to camp? Uncertain, I chose one, headed down the trail, crossed a stream, then another stream, until the valley started to curve. Everything looked different. I turned around and started to backtrack. After a very stressful 10 minutes, I finally recognized a rock formation and soon arrived back at camp. Phew!

A cool lizard we found in the valley was the elusive Baja California Night Lizard, a small and interesting lizard that inhabits only the high forests of the Sierra de La Laguna. 

The next morning — day three —  we headed out of the valley towards the summit. After a few hours of uphill hiking, we finally reached the top, which was rocky with a large white tower. We spent about an hour marveling at the incredible view, highlighted by the Sea of Cortez on one side and the Pacific Ocean on the other.

On our way back down, at first we followed a confusing bushwhack in an attempted shortcut that was supposedly a “trail,” but ultimately decided to retrace our steps instead. At the valley, as I was going to the stream to filter water, I heard a rustling sound and looked down to see an alligator lizard rolling around in the grass. (Yes! There is GRASS in the valley!) I realized that something was biting the lizard and, after a minute, a snake emerged, holding the lizard in its mouth. To my surprise, it was a rare Baja Striped Racer, a fast-moving, day-active snake with two yellow stripes down its back. True to its name, the snake raced out of the grass with the lizard still in its mouth, launched itself into the nearby rock outcrop, then slithered into a hole to eat its prize.

The rest of the trip consisted of knee-killing downhills and a beautiful night back at the swimming hole, before a long descent back into civilization. Overall, it was an exciting, strenuous and eventful trek, after which it took several days to recover. I would definitely do it all again. The Sierra de La Laguna is a magical place. – If you want to talk or walk reptiles, email ChanceStevens123@icloud.com

Sierra de la Laguna, Part 2

Sierra de la Laguna, Part 2: When I got to camp, it was nearly empty, and I realized that my dad and the guide were not there yet. After an hour or so, they arrived. At this point, I was starving, and was super excited to cook my freeze-dried pasta primavera, but sadly realized that the fire would be occupied by the camp guides for the next three hours. This was disheartening, to say the least. That evening, I did finally get to indulge in my pasta, though I realized I had been majorly over-excited about it, since it really wasn’t that great.

Early the next morning, my friends and I left early. Our guide said we could go, but cautioned us not to explore the valley, as it was huge and we could get lost. We made good time. The first part of the hike was extremely steep, but it soon leveled out and we hiked among beautiful high-elevation pine forests full of small Black-Tailed Brush Lizards. Around midday, we arrived at the valley, a sizable meadow with meandering streams criss-crossing it. I could tell immediately that I would love it there. 

The valley was surrounded by tall trees and rock piles, and these rocks continued onto the edge of the valley, which seemed not quite as large as I had expected. I walked around the edge for a while, flipping rocks, and then, under a large rock, I found my first-ever San Lucan Alligator Lizard, which would prove to be the first of many up in the valley. They are fascinating lizards that sometimes move in a snake-like way, wiggling through the grass, with very long tails. They live primarily up in the mountains of Baja. After that first one, my friends and I found probably 10 more.

I then reached the opposite side of the valley, where a narrow strip of meadow connected us to a HUGE meadow. We had merely experienced the pinky toe of the valley, and this Blew My Mind! I headed out into this new meadow, saw a very good flat, large rock, flipped it, then saw another one, flipped it, and so on. After about half an hour of this, I turned around and started heading back. After a minute of walking, it dawned on me that I didn’t recognize anything. Wait, which way was camp? – If you want to talk or walk reptiles, email ChanceStevens123@icloud.com

Sierra de la Laguna: Part 1

Sierra de la Laguna: Part 1. In early March, some friends, my dad and I had an adventure hiking the highest mountain in BCS in search of rare reptiles.

This mountain in the Sierra de la Laguna Mountain Range is known as the Cima de la Sierra, although you can’t even see the Cima until you are already high in the mountains. This four-day backpacking trip ended up being an incredible experience, despite the many ups and downs (ha ha, literally). Anyway, this will be a three-part series describing that adventure and what we found on it.

The day before it all started was a scramble to get on the road, as usual. However, unlike usual, we were able to depart only about an hour behind schedule. By evening we had made it to Rancho San Dionisio, which is essentially on the trailhead. We spent the night there and made it onto the trail by mid-morning. The first hour was quite pleasant, and we were in good spirits.

I was very excited, as our first camp was going to be at a beautiful swimming hole. I was also excited because I was going to have a freeze-dried pasta primavera for lunch, among our freeze-dried food assortment. Unfortunately, due to a miscommunication, our cookstove was left in the truck. Our guide insisted we would have fires to cook on and we already had way too much stuff, so it was left behind. That would prove to be a grave mistake. 

The trail then changed, and we were now trekking up a steep hill. After about five hours of hiking up a mountain in 85-degree weather, we finally arrived at the beautiful swimming hole surrounded by stunning rock lizards. After freezing half to death in the tropical desert ice water, I headed up to camp to have lunch but, when I got there…

Common Dolphin

Common dolphins (Delphinus delphis) are the most common cetacean in the world, they are found worldwide, through tropical and temperate waters, nearshore and offshore. Despite their name, they are not the dolphin we have in mind as the “classic dolphin”, being this one the bottlenose dolphin, popular in media or aquariums. Common dolphins have a well-defined long beak, a black-grey back, and a dark patch around the eye, they can be easily recognized by a pale to tan hourglass or crisscross pattern on the sides of their bodies.

They form large groups for hunting and socializing, it is not rare to see hundreds of them in a group. Sometimes, they can form bigger groups called “super pods”, gathering thousands of individuals. They are very playful when they swim in groups and enjoy breaching and playing with waves, they are known for swimming along with boats, either racing at the front or playing at the wake that is formed behind.

Because of their wide distribution, they have a varied diet, feeding on schooling fish like anchovies and sardines, among other species, and enjoy eating squid too. They have been recorded to make dives up to 200 meters (660 ft) deep.

Recently we had big groups of common dolphins in the bay, and what is even better: there were many babies with them! Given that newborn calves measure 7 to 100cm (2.3 to 3.3 ft) I would say these babies were recently born, I had never seen such

Spring Snake Emergence

It is now late winter, and the weather patterns are starting to shift. As it warms up, the reptiles wake. It is a magical (for me) time of year, because the spring snake emergence will soon be upon us. 

Snakes are mysterious and elusive creatures. Throughout the winter, they are typically very hard to find, mostly because they are cold blooded and need heat to operate properly. In many parts of the USA and all of Canada, snakes have to find deep holes in the earth to get below the frost line. In contrast, here in Baja it never gets that cold, and snakes can spend the winter in rodent burrows, root systems and under rocks. They will even occasionally come out to bask in the sun rays throughout the winter.

Now that it is warming up, many snakes will come out to find food and soak up the sun. If you are scared of snakes, you need not worry, since the vast majority here are completely harmless. 

The main place you will notice this snake emergence is on hiking and biking trails. You may worry about the snakes hurting you yet, realistically, you are a Far Bigger Danger to the snakes. All I ask — particularly in this season — is to please be careful when driving through the desert, or even mountain biking. Snakes are very vulnerable to cars and, unfortunately, they like sitting on roads.

Next week I will bring to you… drumroll please… the tale of my reptile-inspired trip to the summit of the Sierra de La Laguna! If you want to talk or walk reptiles, email ChanceStevens123@icloud.com
