…it’s their fingers that count!

I just got back from a ten-day excursion to the Caribbean coasts of Panamá and Costa Rica.  I went with Sarah (from Bloodsport!) and Rachel, a resident naturalist.  The entire trip they talked about visiting the Aviarios Del Caribe Sloth Sanctuary of Costa Rica.  They had been sold on the idea by this video of a baby two-fingered sloth, recorded on-site.  They said it would be cute.

So we went.  And it was cute.

Even the bathrooms were endearing, which is always a welcome surprise in rural Costa Rica.

Next to the bathrooms was a “Wall of Learning,” where we learned.  First, we learned that the common ancestor of modern sloths was a huge, terrestrial herbivore.  The sloths’ ancestors took to the trees to escape predators on land, and adopted a laid-back, inconspicuous lifestyle.

Geology Minute! As you can see, the Central American landmass is relatively young. It was formed by the slow collision of the Pacific Plate and the Caribbean Plate. The Pacific Plate slid beneath the Caribbean, and the ensuing underwater volcanic activity began forming islands. Indeed, the landmass known today as the Isthmus of Panama—through which we toiled to dig a canal—was but an archipelago as recently as 4 million years ago.

And second-of-ly, I learned that the animals we call “sloths” belong to two very distinct families, no more closely related to each other than they are to armadillos or anteaters:

But let’s meet some real sloths.

This is Buttercup, and she loves you.

Buttercup is a 17-year-old, three-fingered sloth, and the story of the Aviarios Sanctuary begins with her.

In 1991 the Limón earthquake destroyed the country home of Luis and Judy Arroyo.  They rebuilt it as a boutique hotel, and offered tours of their rich rain forest property.  In 1992, three neighborhood girls brought an orphaned three-fingered sloth to their doorstep.

“We named her Buttercup. Finding very little useful information about sloths, we learned from experience – and a very hefty dose of common sense! Then, another sloth arrived. And another. Before long, we became known as authorities on sloth rescue and rearing – and sloths kept coming. Buttercup became the most loved and photographed sloth in the world.”

I didn’t get to meet Mrs. Arroyo, but I met Luis when he mistook me and my companions for the new volunteers scheduled to arrive that day.   This majestic portrait of the Sloth Godfather hangs in the gift shop, and it says more than I could hope to about a man with whom I spoke only briefly.

Let’s say goodbye to Buttercup for now, and go check on the little ones.

Bye, Buttercup

The sanctuary is home to more than 150 sloths, including more than a dozen babies in warm, fluffy, slowly churning heaps.  Since sloths reared together in captivity do not breed, these babies were orphaned, either in the wild or in captivity, born to dying mothers brought to the sanctuary too late.

This is Fozzy, a two-fingered toddler:

waka waka

waka waka!

Fozzy is about 11 months old, I think, which is toddler-age for a sloth.  I might be talking out of my ass here, but I can’t be that far off.  Sloths reach adulthood around age 3, and they can live beyond 30.  Fozzy is particularly rambunctious; he continually pawed at our tour guide and twice sallied from his crate, languidly craning to bite her arm.

His roommates were chiller:

Sloths are natural-born yawners

So what’s the difference between two fingers and three, besides a finger, smartasses?  Well, I’ll let Wikipedia help me tell you about both.  I hope you learn something.

First, Choloepus hoffmanni, known commonly as the two-fingered sloth.

Two-toed sloths spend most of their time in trees, though they may travel on the ground to move to a new tree, and are excellent swimmers. They are strictly nocturnal, moving slowly through the canopy after dark, munching on leaves. The name “sloth” means “lazy,” but the slow movements of this animal are actually an adaptation for surviving on a low-energy diet of leaves. These sloths have half the metabolic rate of a mammal of the same size. Sloths have very poor eyesight and hearing, and rely almost entirely on their senses of touch and smell to find food.”

Note: While adult two-fingered sloths are strictly nocturnal, juveniles are often awake and active during daylight hours.

Asleep.  What a surprise.

Two toes = sleep during the day (nocturnal)

Two-toed sloths hang from tree branches, suspended by their huge, hook-like claws, which are two to three inches long. Sloths sometimes are found hanging off trees after they die. Nearly everything a sloth does, including eating, sleeping, mating, and giving birth, is done while hanging from the branches in the trees. The only time that sloths are normally found right side up is when they go down to the ground to defecate, which they only do about once every 5 days.”

Another note: when sloths do defecate, they can lose up to one third of their body weight.  Whoosh!

twotoedskeleton

Sloths have many predators, including the jaguar, eagles, and large snakes. If threatened, sloths can defend themselves by slashing out at a predator with their huge claws or biting with their sharp cheek teeth. However, a sloth’s main defense is to avoid being attacked in the first place. The two-toed sloth can survive wounds that would be fatal to another mammal its size.

The sloth’s slow, deliberate movements and algae-covered fur make them difficult for predators to spot from a distance. Their treetop home is also out of reach for many larger predators. Their long, coarse fur also protects them from sun and rain. Their fur, unlike other mammals, flows from belly to top, not top to belly. This is so that when it rains, and they are hanging upside down, the rain slides off the fur easily.”

And three-fingered sloths?  I’m borrowing part of the Wikipedia entry for Bradypus variegatus, or the brown-throated sloth, one of several species of three-fingered sloth, and the most common in my area.

It is the most widespread and common species of the group, being found in many different kinds of environments, including evergreen and dry forests and in highly perturbed natural areas.

It is a solitary, nocturnal and diurnal animal, feeding on leaves of many species of trees.

The female of the species is known to emit a loud, shrill scream during the mating season to attract males. It is a cry that sounds like “ay ay”. This scream has been remarked to sound exactly like that of a woman screaming. The male can be identified by a black stripe surrounded by orange fur on its back between the shoulders.”

We did indeed hear that scream, and I was shocked that a docile creature like Buttercup could make such a racket.

Three fingers = active during the day (diurnal)

Note how her neck is twisted in the photo above.  Three-fingered sloths can turn their heads up to 270 degrees, which is helpful when you spend life upside-down.  This remarkable ability is facilitated by extra vertebrae, visible in the photo below.

skeletonneck

The Brown-throated sloth has grayish-brown to beige color fur and it is very coarse and stiff. A sloth has a round head and on it there are two eyes, a blunt nose, peg-like teeth, and ears that are not visible. The tail of a sloth is very small.

Over parts of its range, the Brown-throated Sloth overlaps the range of Hoffmann’s Two-toed Sloth. Where this overlap occurs, the three-toed sloth tends to be smaller and more numerous than its relative, being more active in moving through the forest and maintaining more diurnal activity.”

But that’s not all!  Three-fingered sloths are ecosystems.  Somewhat like the cecropia tree (which is only slightly less mobile) three-fingered sloths host a symbiotic commonwealth of beetles, moths, molds and algae that thrives within their nappy fur.

The algae and mold naturally camouflage the sloth by turning it green.  Insects feed on the algae, including a species of moth, Bradipodicola hahneli, more commonly called the “sloth moth.”  The sloth moth lays its eggs in the sloth’s poop.  The eggs later hatch and the brood flies off to find another sloth.  Miraculous.

The sloths at the sanctuary are algae-free because they don’t get wet all the time the way they would in the wild.  This hardly diminishes their quality of life, as sloths have been known to starve to death in the wild during prolonged periods of rain.  That’s right⎯starve. Sloths need to keep warm in order to nourish the good bacteria in their bellies that help digest the pounds upon pounds of leaves they eat.  If they can’t get warm, they can’t digest their food.  Sloths can starve to death with full bellies.

With the Internets as my witnesses, I anoint you all sloth experts.  Now let me show you my baby pictures:

This itsy-bitsy baby sloth arrived at the sanctuary with fungus in his fur, so he got shaved.  To keep him warm, special jammies were made from socks.

That’s my mom humming along a zipline in Selvatura Park.  A guide is with her for extra weight because that particular cable (one of 18) is one kilometer in length.  If you get stuck in the middle of that line, you better have already gone to the bathroom.

Selvatura Park is a really cool place with loads to see and do, but they pay people to tell you all about that, so I refer you to their Web site, linked above, if you care to learn more.  The Ecolodge makes arrangements for our guests to visit there, and it’s something every visitor should do.  

Something every visitor might not be willing to do, however, is the “tarzan swing” toward the end of the zipline canopy tour.  But how can you know you won’t enjoy being shoved off a twenty-foot scaffold to swoop inches above a concrete platform, unless you try it?  I’m pleased to report that both my sister and mother are qualified to take an informed stance on the issue.  Here’s what they had to say:

Afterward we visited the Hummingbird Garden, where we actually heard the birds humming.  The Nahuatl word for hummingbird is huitzil, an onomatopoeia describing the sound of their wings.  Imagine a dozen enormous bumblebees around you.  These weren’t skittish at all, and I was able to get quite close.

At present count, Costa Rica is home to some 51 species of hummingbird.  14 species are found in Monteverde.  This one is a coppery-headed emerald, and it is endemic to Costa Rica, meaning that it is found nowhere else.  Costa Rica, especially the Monteverde area, teems with such unique fauna.  

She looks to be a female; males of the species sport rich stains of copper plumage.  This difference is an example of sexual dimorphism, a common pattern in wildlife that is especially pronounced in birds.  Obviously one expects some vital anatomical differences between males and females of any species, but whether or not a male gets to appreciate them firsthand hinges on making a good first impression.  A good first impression, in turn, hinges on being physically conspicuous—that is, attractive.  I’m sure this is old news to every living thing on the planet, but it’s a rich topic, full of surprises.  Like this

Below is a violet sabrewing.  They’re big—the males push six inches—but they are not proportionally territorially aggressive in the wild.  In the garden, however, they were rambunctious, driving smaller species from feeders.  This is a male.  The female sabrewing has violet only on her throat, and is otherwise green and gray.  This guy doesn’t seem to fit his own description, either, but this is an effect of lighting and perspective.  The male sabrewing’s coruscating plumage plays the spectrum from B to V, and they don’t hold still very long, even when feeding.  This is the best shot I got.

Here is a hummingbird nest, discovered on a tour of the Butterfly Garden.  My thumb is for scale.

The Selvatura Butterfly Garden is a vast enclosure full of flowers and butterflies.  We explored it as a guided tour audience, but I didn’t listen to anything the guy said. No, that’s not true.  I remember only that at the end the poor kid bungled a Costa Rican joke that, due to his poor English and the fact that puns generally don’t translate, made absolutely no sense.

There was a nursery of chrysalises in a cabinet, and clumsy newborn butterflies falling out.

Guys!  Come quick!  It’s a dead monkey!  Like, fell right out of a damn tree!  Make sure your speakers aren’t muted.

Click me!

I shot video because I thought the audible reactions of the gathered giddy rubberneckers would be worth preserving.  The guy working the sack is Scott, resident naturalist and one of my favorite people.  

And here is a gratuitous picture of myself (one of your favorite people, no doubt) to replace the mental image of cold, dead monkey face.

Last Saturday my mom and my younger sister showed up at the Ecolodge San Luis.  They have since returned home with sunburns and stories.  I was excited to see them—indeed, it proved to be a week full of novelty—but I am also relieved by their departure.  I don’t know if it’s truly possible to have too much fun, but we must have been close.  Don’t believe me?  My mom held a snake on the first day.

On our first full day we took a cab up to Santa Elena to visit the Serpentarium, eat lunch at an overpriced tourist trap, and explore the Orchid Garden.  The Serpentarium is exactly what it sounds like, with one invaluable exception: it doesn’t smell like you have actually been swallowed alive by an exhibit.  This is key.  Visitors to the reptile exhibit at the Tulsa Zoo are scourged by a stench so profane that it can only be black magic wrought by the spirits of dead Indians, upon whose pagan graves the blasphemous House of Reptiles surely rests.  It’s distracting, to say the least.

Not to say that the Serpentarium isn’t gross at times; there’s a whole exhibit of pickled reptiles in jars, set against a collage of snake-bite wound photos.  I’ll show you some.  No, I won’t, actually.  They’re ghastly, and definitely worse than any of my cockfight videos that got taken down.  “Sorry” to some, “you’re welcome” to others.  Have some cute instead:

I don’t really know anything about these two snakes, except that the first is a juvenile and the second is pretty.  I’m kinda burned out on learning about animals for the time being.

Moving on!  After the Serpentarium we hiked to the center of town to eat.  We went to the restaurant at the Tree House Hotel.  I do not recommend eating there, simply because the food is expensive but otherwise unremarkable.  

We then walked to the supermarket, where we bought several bottles of wine and a little something for me to share with my colleagues.  Naturally the burden of carrying all of this for the rest of the afternoon fell on me.  That doesn’t sound like much, but I also carry about 25 pounds of gravel in my backpack to keep my daily waterfall treks challenging.  I tell you this only to help explain the absence of photos from the Orchid Garden we then toured, for I quickly grew resentful of every blossom that delayed our progress toward the bench I knew to be at the trail’s end.  

When we finally got there, I sat down, cheered up, and snapped this Motmot.  It’s a fairly common bird here, but impressive nonetheless.

Well, that does it for the first day.  More to come.  Lots more.

Today a stow-away ant bit me inside my pants, inspiring me to thrust and gallop across the main lawn, slapping my own ass in a frenzied, lunatic haka.  For Science.

I had visited, as I often do, the same leafcutter ant trails from my first big post.  (No matter how many monkeys and bats this country throws at me, I keep coming back to the ants.)  But this time I had an idea for an experiment that seems, in hindsight, an irresponsibly tedious exploit for a blogger—I really shouldn’t even be boring you with the details—but here we go.

Wait, no.  First, look at this:

What a goofball

This is a leafcutter soldier with its mandibles stuck in the seam of a split twig.  The soldier’s own weight has caused the stick to sag like a falling drawbridge, trapping his face forever.  Divinely, I intervened and gave him a second chance to toil all the way to the grave.  I sure earned my two scoops of raisins today.  Anyway, back to my exciting research:

As more than one person has pointed out to me, the experiment should have consisted of mortal combat between exotic pairings of ants and other living things besides leaves.  Anything but leaves.  So I obstructed each side of a fork in the ants’ trail with a different leaf, and I checked every so often to see which leaf disappeared first.  Let’s go to the re-play:

In this corner, a fern-like specimen!

I'm so sorry, you guys

I'm so sorry, you guys

…And in this corner, a not-fern-like specimen!

Strongest leaf in USSR

Most great fight leaf in USSR

Yes, this leaf had clearly been chewed already.  The whole affair was amateur hour.  Anyway, I’ll just let the pictures tell the story.   At 2:37 p.m. the race was on:

There you have it.  The ants chewed on both leaves a little, but apparently the obstacles didn’t warrant a major diversion of labor.  What does it mean?  I’ll let you decide, because I am so over the task of wringing significance from this particular caper.  Let’s rinse this taste out with monkeys.  I’m going to show and tell about monkeys.  Stay tuned.

This will very likely become an actual T-shirt, so if you think you'd buy one, say so in the comments.  I'll try to get some made that fit people who can already read.

This will very likely become an actual T-shirt, so if you think you'd buy one, say so in the comments. I'll try to get some made that fit people already know how to read.

This is my design of a T-shirt celebrating literacy, intended for distribution among the children of San Luis, and which the EcoLodge also plans to sell to guests and students.  They might also be available in black, which looks pretty darn cool, too.  Only one more person has to approve it before real people can start wearing real shirts bearing that image.  You saw it here first.

Everybody groovy is reading.
