North Seymour Island

Posted on December 16, 2020December 16, 2020 by Lark

The day after we explored San Cristobal’s highlands, we made our first relocation from San Cristobal to Santa Cruz, the second largest island in the Galapagos and home to their most populous city, Puerto Ayora. After a few days in Puerto Baquerizo Moreno, San Cristobal (~7,000 inhabitants), Puerto Ayora (~12,000 inhabitants) made me feel like a small-town girl in the big city. It was a bit jarring. Also a bit jarring was the ferry ride… I spent most of it with my eyes closed, praying it would end soon and lying to myself by saying that I didn’t feel the least bit seasick. (And like I’ve said before, I do NOT get seasick easily. It was rough.)

To keep you oriented, we left from San Cristobal and headed west to Santa Cruz! As you can see, lots of open water which probably didn’t help with the ride’s seasickness factor.

The next morning, we were back at it with another tour, this time going to the uninhabited island of North Seymour, north of Santa Cruz. We had a bit of a hybrid journey this time. Puerto Ayora is on the southern coast of Santa Cruz, so we took a 45-minute bus ride from town to the island’s northern port, and from there, we took a 40ish-minute boat ride to North Seymour. Well, actually “yacht ride”. This was a fancy tour which meant hellooo, luxury! The yacht had real bathrooms, air conditioning, and an upper deck! That was the best part. Our family claimed the upper deck while everyone else sat inside in the A/C. Whew! Too much luxury like that and I’m going to be ruined for traveling on the cheap! Just kidding, but it was a fun one-time thing.

We started in Puerto Ayora, took that one road to the north end of the island, and then yachted to North Seymour (circled). Baltra (beneath that) is the location of one of the airports, and that’s where the land iguanas came from (you’ll know what I’m talking about soon).

Unlike many of the archipelago’s islands, North Seymour was NOT formed by a volcanic eruption. It’s a seismic uplift, formed when the Earth’s crust was pushed up by the lava underneath it over the course of thousands of years until it lifted above sea level, forming an island. As a result, it’s very flat (the max altitude is only about 90ft/28m) with dramatic cliffs along the shoreline, and evidence of its previous life as part of the seafloor is abundant, with shells and large rocks scattered across the island. It’s also small, only about 0.75 square miles (~2 square kilometers) in area, and there’s not much vegetation. It’s very low and bushy, but that doesn’t bother the TONS of birds that nest there during the year.

Let’s talk about these plants. They look super dead, right? They’re not. They’re Palo Santo trees, and they lose their leaves to help them survive when there’s not enough water. So as soon as the rainy season comes, they bloom! Palo Santo is considered a cleansing/purifying plant, and its oil is used for aromatherapy and incense.

Once we reached the island, we started off with a walking tour. North Seymour is known for being a great fishing and nesting site for birds, especially frigatebirds. They’re the weirdest! The males have these red chest pouches that inflate during mating season because what could be more attractive than that? The mating ritual is the weirdest thing. We didn’t see it, but my goodness, look up a video because I can’t possibly explain it. Nonetheless, I will try. The males build nests. They sit in their nests, puff up their chest pouches, spread their wings, and then make this noise that can only be described as extraterrestrial. Their entire bodies vibrate from the effort. And the females fly around until they find a nice nest and pouch, and when they land nearby, the males wrap their wings around them to tell other males to scram. The exciting thing about North Seymour is that you can find frigatebirds nesting year-round whereas, in other places, it’s a rare treat to get to see a puffed frigatebird (unofficial terminology).

Okay, opinions, everyone. Does this look comfortable?

Fun fact, it takes about 20 minutes for a chest pouch to inflate

Someone asked the guide what would happen if the pouch was punctured. All he said was, “It would be very bad.”

I’m sure that pouch is great for cutting down on wind-resistance… not.

And if you’re wondering what it looks like uninflated… I think seeing it like this makes the size of the inflated pouch even more amazing.

There are actually two varieties of frigatebird found on North Seymour, the magnificent frigatebird (which is endemic to the Galapagos) and the great frigatebird (also found elsewhere). They look very similar, especially the males. The magnificents are slightly larger with a purplish sheen to their black feathers, and the greats have a slightly wider wingspan and a greenish sheen. They also make different noises, and the great frigatebirds go farther from land to get their food, which is good because then they don’t compete with one another for resources. The guide pointed out both varieties and I think I have pictures of each, but don’t quote me…

I’m no expert, but this sure looks like a great frigatebird to me (greenish feather tint).

And this one looks like a magnificent (purplish feather tint).

The females are easier to tell apart. The magnificents have a blue eye ring and a black throat, while the greats have a red eye ring and a white throat. I don’t think we saw any great females, or at least I haven’t found any in my photos.

Female frigatebird in flight (I think? I’m really not great at this whole birding thing). They’re majestic.

Of course, the females don’t have quite the same pizzazz as the males.

And we saw some chicks and immature frigatebirds which I attempt to identify below…

An immature frigatebird. And I don’t know this for sure, but I think it’s a great frigatebird because of its rust-colored head. But I could definitely be wrong on that.

I really feel like this one is looking at me.

Anyway, the chest sack isn’t the only odd thing about frigatebirds. They don’t have waterproof feathers, so unlike many of the other Galapagos birds, they can’t go diving for their food. Instead, they eat things off the surface, like crabs, squid, flying fish, small turtles, etc. and sometimes they steal food from other birds, earning them the nickname “pirate birds”. At first, I thought this meant that if another bird was carrying a fish or something, they’d make them drop it. NOPE. Well, that is part of it. They dive-bomb other birds and make them drop their prey… but more disturbingly, they sometimes make the other bird regurgitate its food, aka they eat bird vomit. How do they do this? Either by chasing them around until they’re so stressed out that they throw up, or by grabbing them by the tail feathers and shaking them around until achieving the same result. And then they swoop down and grab their “food” (ew) before it hits the water. Nature is gross.

I know it’s hard to tell, but these frigatebirds are sitting on nests. They often re-use nests from year to year and sometimes steal nest materials (not shocking considering they don’t seem to understand ownership boundaries like “after I’ve swallowed a fish, it’s mine”).

Other interesting/less gross facts… they have a really high wingspan to body weight ratio which makes them great at gliding and maneuvering. Their wingspans are up to 8ft (2.4m)… which is crazy. Their bodies are about 3.5ft long (1m), so it’s not like they’re small birds in any way, but still. They can spend more than a week floating on wind currents! They also care for their babies longer than any other bird. A baby starts to fly at around 4-6 months, but the mother continues to supplement its diet for another 6 months to a year+, depending on oceanic conditions (in years when it’s harder to find food, the length of care is usually longer).

The male frigatebirds help after the baby hatches, though they may not stick around for quite as long as the mom. This guy is currently watching over his little puff ball.

The male frigatebird definitely understands what it means to suffer for the sake of beauty.

Blue-footed boobies are also a big attraction of North Seymour, and people come to watch their weird mating ritual which, most famously, includes some dancing. They lift their feet one at a time like they’re casually trying to show off their vibrance, bow their heads, maybe give a gift, and finish off with a finale of wing-spreading and head-lifting. If a female is into it, she goes over and joins the dance. Unlike frigatebirds, blue-footed boobies are great hunters which, unfortunately for them, makes them a frequent target for the pirate birds.

I’m no expert, but I don’t think this blue-footed booby was very happy to have us around. But look! Eggs!

This blue-footed booby is still immature, which you can see because he’s still mostly brown. The adults have a lighter head (see next picture). He’s also clearly not ready for mating because his feet are so dull. They get much brighter when it’s time to find a mate.

Booby and alien-bird booby baby. You can see that this adult’s head is much lighter than the dark brown immature booby from the previous picture. And look at those feet!

Even as an uninhabited island, North Seymour has had its share of issues with non-native species messing with the island’s ecosystem, primarily rats. There was a big effort to eradicate the rat population in the 2000s, and by 2007, the island was rat-free. About 10 years later, though, in 2018, more rats were discovered. You may be wondering how they got there… Did you know that rats can swim? Some can swim for over a MILE (1.6km). Baltra Island, home to one of the islands’ airports, is within swimming distance, and it’s thought that they came from there.

The rats are a big problem. They eat iguana and bird eggs (and many of the birds on North Seymour literally just nest on the ground), gnaw on the plants and eat their seeds, eat pollinating insects, and reproduce quickly… basically, they wreak complete havoc on the ecosystem. Usually, poison would be spread over the island using helicopters, but that’s crazy expensive and imprecise for such a small land area. So, in early 2019, they tried something new and used drones to drop the poison! This was great because they’re much more precise which means that they could minimize water contamination, and it’s much cheaper than renting a helicopter! The island was closed for a few months, and they think that the rats have been completely eliminated which is pretty cool. They’ll keep monitoring the island for the next two years to see how the ecosystem is recovering and to make sure that no rats return.

Imagine swimming in that beautiful water, looking over, and seeing a RAT swimming next to you. Ew ew ew!

I think it’s really interesting to hear about how they’re trying to repair these island ecosystems because it’s such a unique situation. Since they’re islands, you can actually contain the problem and control more of the variables, unlike if you’re working with a larger landmass. Another sort of “test case” that happened on North Seymour involves land iguanas. There are a LOT of land iguanas on the island, but interestingly, they actually aren’t native. These iguanas originated on Baltra Island, but Baltra had a goat problem that was damaging the land iguana habitat and population, so in the 1930s, a few were brought over to North Seymour to give them a better chance of survival. By the 1950s, land iguanas were extinct from Baltra… but since they were thriving on North Seymour, some of them were taken to be reintroduced! The North Seymour land iguanas have also been taken to Santiago, another island where the native population became extinct, and have repopulated there as well.

Land iguana on the moon. Seriously though, what a trippy landscape!

Land iguanas are larger than the marine iguanas that we’ve seen before, and unlike marine iguanas, which you’ll see in large groups on the coast, it’s rare to see more than one at a time. They are vegetarians and mostly eat cactus pads which seems like a painful diet, but they have really thick skin in their mouths, so they can eat them spines and all!

I have a lot of pictures of this guy and had trouble choosing just one… so I didn’t.

He must have been doing a lot of push-ups because he has some chest definition (kidding, I don’t know if land iguanas do that… but some lava lizards actually do defend their territory via push-up competitions, so it’s not completely out of the realm of possibility).

Marine iguana. You can see that the coloring is COMPLETELY different from the land iguana.

Before heading back to the boat, we walked along the beach, looked at some sea turtle nests, and visited a lake where the guide said you can sometimes see flamingos! We lucked out, and even though it was suuuper far away, it was still awesome to see.

Sea turtle nest. The mom sea turtle comes out of the water at night, digs a body pit and then an egg chamber, plops out the eggs, covers the egg chamber and does some camouflage with dry sand to try to hide the nest from predators, and then she gets back into the ocean and says, “Later, eggs! Good luck!” And they definitely need luck to make it to adulthood. First they need to even hatch, then they need to make it to the ocean without being eaten, and then they need to grow big enough to not be an easy target for every bird and other predator they might encounter.

We had a little time for swimming and snorkeling before the end of the tour, too. I didn’t take my camera with me, and even though there were some cool fish, I didn’t regret it because the water wasn’t very clear. You’ll just have to imagine.

After that, we headed back to Santa Cruz, and everyone was exhausted by the time we got back to the hotel. We did go on one more adventure that night… my aunt read that you can sometimes see sharks from the end of the pier because the lights illuminate the water, so we figured we might as well check it out (especially since I thought it might be good to see a shark from outside of the water to help me get over my paralyzing fear of them). We weren’t expecting much, but we actually did end up seeing a few!! They were maybe like 3 feet (1m) long, and it was hard to see because it was dark, but still, how cool! Enjoy my super clear photo… I promise it’s a shark.

San Cristóbal Highlands

Posted on October 23, 2020 by Lark

Following our two days of full-day tours, we “took it easy” with a “free” day that ended up being one of the most exhausting of all. We didn’t have an official tour scheduled, but that doesn’t mean we didn’t have any plans. We hired a taxi driver to drive us around the island, doing the classic “highlands tour” circuit that goes from end-to-end on the island’s one major road.

We started in Puerto Baquerizo Moreno, then visited the Galapaguera de Cerro Colorado (tortoise reserve and breeding center), Puerto Chino (one of the many “world’s most beautiful” beaches), Laguna El Junco (lake), and finally stopped at the island’s oldest ceiba tree/treehouse before heading back to town where we had some other adventures on foot. Like I said, it was quite the day.

To give you some context…
We started at the blue house at the western end of the island, then we went to the Galapaguera (green), Puerto Chino (red), Laguna El Junco (blue), and the ceiba tree (yellow). After getting back to town, we walked up to the Interpretation Center and Cerro Tijeretas (purple).

Let’s not get ahead of ourselves, though! Our first stop was the Galapaguera, a tortoise reserve that was opened in 2003 to help rebuild the island’s tortoise population. There were originally 15 subspecies of Galapagos tortoise. Four of those are extinct, and all of them are endangered, mostly due to human activities. During the pirating/whaling days, it’s estimated that 100,000-200,000 tortoises were taken and killed for their meat and oil. In addition, non-native species were introduced that hindered repopulation. Rats, pigs, snakes, and army ants eat eggs and threaten hatchlings (as do some of the native birds). Goats and other large mammals compete with them for food.

Tiniest lil baby tortoises!! These could easily fit in your hand, maybe like 5″ (13cm) max in length.

And these are big enough that you could ride around on their backs.

One of the things that saved many of these tortoise subspecies is their longevity. They live an average of 100 years with the oldest recorded living to 152! This meant that even with the many repopulation challenges, only a few tortoises needed to survive to make conservation efforts possible. Many of the islands now have tortoise reserves and breeding centers which aim to grow the tortoise populations by giving them safe places to mate and grow and eventually releasing many of them into the wild.

In the breeding centers, park rangers collect the tortoise eggs and simulate normal conditions while also protecting them from predators. They incubate the eggs, and after the tortoises hatch, they are kept in growing pens for their first few years of life to further protect them while their shells are still soft. After this vulnerable period, there are virtually no predator risks for the tortoises, and survival is just a matter of finding enough food. The amazing thing, though, is that they can survive for up to a year without eating or drinking! They have a slow metabolism, and they spend more time resting when there isn’t enough food. They also can store water internally for long periods, so they’ll drink a lot when they have access to fresh water and save it for later. (This is actually part of the reason why they were so desirable on ships because they could survive in the ship’s hold without needing food or water, allowing the sailors to have fresh meat at sea with little effort.)

This is where the smallest tortoises are kept until their shells get hard enough. I think they said the first 4 years? Or at least the first two. The fencing on top is to keep out predators, and at night, another cover with even smaller holes is closed as well to protect them even further. (pic by my uncle)

These tortoises were around 5 years old, I think. They’re maybe 1.5′ long (0.5m). Maybe.

This guy was a little freaked out by us. When they get scared, they pull their heads into their shells and use their arms to shield the opening.

We were lucky to arrive at the reserve just in time for feeding! The tortoises are fed twice each week, and the rest of the time, they fend for themselves by eating plants around the sanctuary. Usually, the tortoises are wandering around and you may or may not see many of them, but since it was feeding time, we saw them all! It was really interesting to watch them interact with one another.

This video shows a tortoise “fight”. The dominant tortoise is generally the one that can stretch out its head to be tallest, and you can see that happen in this interaction. Tortoises generally don’t make noise, so it’s just a silent challenge, silent fight, and silent retreat (well, aside from my uncle’s narration hehehe).

‘Get out of my way!” Mr. Tortoise says as he steps over his fellow tortoises.

While we’re at it, here’s one more video showing a tiny tortoise stuck on its back. Some of his friends tried to give him a hand, but ultimately, one of the employees came and flipped him back over.

After we were satisfied, we loaded back into the taxi and headed for Puerto Chino. It’s another SUPER BEAUTIFUL beach, supposedly one of the most beautiful in the islands, but I don’t know. They’re all kind of the same and all very pretty. We weren’t planning to go swimming, so I spent my time practicing taking pictures of sea lions, lava lizards, and this pretty yellow bird that kept flitting around.

Path to Puerto Chino. It’s very nice and paved, but hopefully you don’t need any shade along the way…

You’re supposed to keep 6 feet between you and any animals… but the sea lions do NOT make it easy.

We considered eating lunch at this picnic table, and then a sea lion came and plopped himself right on top.

Puerto Chino. What do you think about the beauty of this beach vs. the others we’ve seen so far?

I’m obsessed with the lava lizard facial expressions

From there, we headed to Laguna El Junco, a volcanic crater lake that’s one of the only permanent freshwater supplies in the islands. Now, this goes back to what I mentioned in a previous post about the crazy diversity of landscapes on a single island. The lake is at 700m above sea level, putting it in the “highlands” category which means it’s green and damp and can be foggy while the coasts are simultaneously clear and dry. So even though the weather was beautiful in town, it was VERY foggy at the lake. Even so, we hiked up to see what we could make out through the fog.

At first, nothing. We couldn’t even see across to the other side! But the wind kept the fog moving, and we were lucky to get a few moments of decent visibility. The lake is about 300m wide, and it’s filled by rainwater. Birds like to swoop around and use the water to clean the salt out of their feathers. It felt like we’d stepped into another world! I was happy enough with being able to see the opposite side of the lake, but on a clear day, they say you can see nearly the entire island as you walk around the rim of the crater!

Path leading up to the edge of the crater

Looking back towards the parking lot. Look at the solid layer of fog at the top of the picture!

Plants around the edge of the crater lake

Panoramic picture of the lake during the few seconds that the view was kind of clear

We made one last stop on the way back to town, in the tiny settlement of El Progreso. This is the oldest surviving settlement in the Galapagos, and if you recall from the history post, it has a horrible past. It was a penal colony, and eventually, this guy named Manuel Cobos turned it into a sugar mill. He started treating the workers like slaves, and they ultimately killed him for his cruelty. Now, about 500 people live in town, and it’s also the home of the islands’ oldest ceiba tree! Ceiba trees aren’t native to the islands, but it’s assumed that this one was planted by some of the earliest visitors. It’s said to be ~300 years old which is possible but maybe unlikely because the first settlement attempt wasn’t until the 1830s. But who knows? It is monstrous: 131 ft tall (40m) with a 61ft circumference (19m).

There’s a bridge leading up to the treehouse

The tree is interesting enough just in itself, but it also features a treehouse! And it’s not your average built-by-a-kid treehouse. You can actually rent it overnight, and there’s electricity and wifi (the two most important things, of course), a loft with two beds, a kitchen, and a functioning bathroom (including a shower!). Craziness. And underneath the tree, there’s an underground room where I lasted about a minute before I started thinking about the fact that we were underneath a tree, and if the room collapsed, we’d be dead. So that wasn’t exactly my favorite part, but it was still cool.

Inside the treehouse. The beds are up in the loft, and the kitchen is straight ahead.

My cousin coming up from the underground cave

This is the garden outside of the treehouse. So pretty! (The treehouse is behind me to the right. You can see some of the tree branches sticking into the picture.)

That was the end of the highlands tour, but like I said, it wasn’t the end of our day! After the taxi driver dropped us off back in town, we walked to the Interpretation Center which has a bunch of information about the islands: how they were formed, their human history, the ecosystems and flora and fauna. It’s actually where I got nearly all of the content for my Galapagos History post.

From there, we walked up a nearby hill, Cerro Tijeretas, where you can get nice views of the town and other parts of the island. You can even see Kicker Rock from there! It overlooks a pretty snorkeling spot, and there are a lot of frigatebirds flying around because there’s a colony that nests nearby.

Looking back towards Puerto Baquerizo Moreno

This is supposed to be a really great snorkeling spot

Do you see Kicker Rock out there in the distance??

We also popped into a couple of beaches along the way, Playa Punta Carola and Playa Mann. They were fairly crowded because they’re public beaches close to town (especially Playa Mann). I guess if you’re looking for a beach vacation, that’s where you’d go? But I don’t think I’d recommend going to the Galapagos if you’re interested in just chilling on a beach. Save that for a less interesting place.

I guess this beach is kind of pretty too

I was ready to collapse at this point, but my uncle really wanted to go to ANOTHER beach, Playa Lobería, to watch the sunset. We grabbed a taxi and got there only a few minutes before the beach closed, but that was enough time to look at some adorable little sea lion babies and take a few pictures of the sunset. After THAT, I really was toast. We got some dinner before heading back to our apartment, and I feel confident in saying that everyone slept like a rock that night.
