Today, my alarm does not go off, so I cannot go birding. After breakfast we go to Rolando’s property to plant trees. On our route there, I spot a Southern Rough-winged Swallow sitting on a telephone wire and a Crane Hawk soaring, which I identified by a white stripe running down the wing near the tips. It is much easier going today as it is cooler in the shade and we only need to plant half as many trees as yesterday (it is still one hundred, but that is one hundred less than previously). We finish our last planting job in about an hour.

After lunch we go play soccer with the locals. Jeff, Sarah, Bryan, Jose, Luigi, Roy, Rolando, and I all played. I scored two goals again. About half an hour into the game, it begins to pour. This is not a rainstorm; it is a deluge. It is raining so intensely that the water stings my back. As it rains, a large tree branch collapses. A tremendous crack rings out and everyone turns around to see half of the 80 foot tree slough off. The tree falls away from the field and toward the bullring. By the end of the game, we are playing in two inches of water. The field is a swamp. Everyone slide tackles because you fly five meters, as the ground is like a slip-and-slide. You cannot dribble as the ball floats in the water. When it is kicked, it just dies on the ground. Everyone is splashing, falling, rolling, and sliding. This is one of those moments which I will never forget.

Sarah and I go on a night hike after the rain lets up. We see several spiders and wonder if spider silk strength at all correlates to spider size (especially per unit mass). We also wonder if the three dimensional webs that we see everywhere here are a result of the necessity for increased robustness to deal with rain and/or larger insects. The spiders here have far more insects to eat than those in the temperate forests, which only produce two dimensional webs. Another hypothesis, we learn, is that extra strands which may seem superfluous actually help birds to see the otherwise invisible webs. Creating these extra strands is much easier than having to produce a whole new web if a bird flies through it. Sarah also notes the water gathering adaptation of heliconia flowers. They are like little cups . A small frog jumps from leaf to leaf. Finally, we see a strange caterpillar creature. It is brown with lime-green splotches on its sides and tiny legs which do not seem to be particularly effective. Most noticeably, they have four long, pink antennae-like protrusions from their heads near their large black eyes. They are eating the leaves of a small sapling. Initially, we think that this may be a cordyceps fungi, which infect insects’ brains and drive them upwards where they die. The fungi then bursts out of the head and grows to a tip, which then splits, sending spores outward, infecting more insects. However, we see that there are two of the same kind and they are both eating calmly. Still, these are very strange creatures which look like a mishmash of various animals or aliens.

I head back and go to sleep, but not before almost stepping on a cane toad. The giant toads are very common here. If run over on a motorcycle, they pop. This is a popular game amongst Ticos, perhaps it is their version of bubble-wrap. The toads are simple creatures, they register the world in shadows. If the shadow is larger than them, they hop away. If the shadow is smaller, they try to eat it. Sometimes they do not know what is making the shadow so they run directly into you.

Today we go birding. We see a Buff-throated Saldator in a cecropia. We also spot several kiskadees loudly calling and flying out of a thicket. We think that it may be a snake, which would cause the birds some consternation.

After breakfast we go to Johnny Diaz’s to work. I ride in the red truck. At one point, the radiator fails. So, Andrus, Oscar, and I hang onto the side of the SUV on our way up the mountain. It seems dangerous, but I believe that it is actually much safer and more comfortable than riding in the bed of the truck. The only problem is overhanging branches, which can, if you do not pay attention, smack you in the face. I feel like Indiana Jones (except without the Nazis). On our way up, we see a Blue Ground-dove, whose light blue coloration is surprisingly pretty.

At Johnny’s place, we chop, shovel, plant, and mark off two hundred trees. The work is exhausting, especially as more and more people seem to be falling victim to a viral infection.

After the work, Johnny takes us to gather some pejibayes. These orange, starchy fruit grows high up in palm trees in large clumps. Oscar climbs what must be 50 feet up the tree and is then handed a long pole to knock the fruit out of the tree. Back by the road, which leads to an absolutely gorgeous vista of the surrounding valley and hillsides, we walk back to the cars. I can only imaginewhat this place must have looked like without pastures and when it was covered by thick, dark, lush forest.

We realize that the SUV, which drove ahead, had Mary’s keys. So, we wait for Johnny to catch up to them on his quad. While waiting, we drink coconut milk, which is not as creamy as I expected. Instead, it is a slightly flavored water.

The ride back in the bed of the truck is very uncomfortable as we are surrounded by shovels, machetes, and buckets. Sitting on the edges hurts your tail bone and squatting in the bed kills your knees. On the side of the road, we see two three-foot-long iguanas and what I believe to be a basilisk lizard basking in the sun by the river. The iguanas are a dark greenish-black and have a brownish-red head.

After returning, I go to the watering hole. I wash and sit there like a lizard, warming myself on the hot rocks below and the sun above. While there, I see a bright, lime-green butterfly, a Ringed Kingfisher, and a bird I thought was a Black-crowned Tityra. Upon my return, Andrus thought it sounded like a Masked Tityra. I wish I had my binoculars so that I could see if it had a red bill and facial skin, the distinguishing mark of the latter bird.

Back at base, we have a lecture on the causes of deforestation. The main reason the forests here are deforested is to simply get them out of the way of plantations and cattle ranches. Some of the wood is used, but it is largely done simply to clear land so that it can be used “efficiently.” After dinner, I go to sleep.

Birdwatching today is a huge success. Any doubts about my aracari sighting yesterday are placated as I see two more today. They appeared to be a pair. Ricardo claims that the aracaris stir up the other birds. Perhaps he is right, because I also see another Bananaquit, a Dusky-capped Flycatcher, which I identified by its color, crest, and lack of visible wing ba rs, and a Red-legged Honeycreeper, whose reddish or pink legs pointed me in correct direction for identification.

After breakfast, we head to Playa Ballena. This is a relatively small beach and a national park. Immediately upon driving into the parking lot, we see howler monkeys. the howlers found here are the Golden-mantled Howler Monkey. The males have a dark gold collar of fur. They lie around lazily as howlers often do. Their characteristic, booming vocalizations are not heard. We see some males, females, and two babies. The latter are the most active. But, perhaps someone should provide them with more instruction, as Ricardo mentions that most monkey autopsies (I smell a CSI spinoff) reveal broken bones from poorly executed jumps.

The beach is much nicer than the one in Dominical. There are no other people here besides us, so we can enjoy the waves and swim around.   We have the beach all to ourselves. The blue green water rises and falls in a froth of bubbles resulting from the crashing waves breaking just offshore. The water is warm, so simply floating on ones back with the son on your face is a wonderful feeling, as you bob up and down on the waves.

After swimming, we begin our lesson. Ricardo points out an amarillon tree, which are natural to this area. They produce nuts which are known as beach almonds. The shells are hard to crack by any animal, save for the strong bills of macaws. The nearby coconut palms were planted, but their seeds can survive for long durations in the ocean, making them a very successful species here. Unfortunately, they do not hold the beach soil as well as the amarillon.

In the distance, we see several islands. There are three small ones to our left and one large one toward the right. These islands are classic sea bird nesting sites, because there are no predators, the birds can nest on the ground (their feet are adapted to paddling; not perching), and the sea breeze helps them hunt.

On our walk, we see breadfruit, which brings to mind Mutiny on the HMS Bounty, and Balsa wood, whose remarkably light wood feels hollow if rapped with your knuckles. We also spot crabs on a rock spot just a few feet off of the coast, as well as two Scarlet-rumped Cacique. They are generally insectivorous, but here, they seem to stare hungrily at hermit crabs scurrying from coconuts on the ground.

After lunch, we sit on the rocky beach, watching the waves. It is absolutely serene. The waves roll in, and as they go back out to sea, they pull pebbles with them, making a rumbling sound if the waves are not too close together.

Aptly named Blue Crabs

Just before we leave, a long, thin, green snake falls on my legs. Matter of factually, I say, “Oh, look…a snake just fell.” Sarah, who was sitting next to me, responded with, “Wait…what?” followed by kicking. The snake, now agitated, slithers up closer to me. Now, the situation is a bit out of control, so I shake it off of me.  Ricardo claims that it is a vine snake as it sends its head from branch to branch in the tree above us with great agility. It is not venomous. Had I known that, I may have grabbed it, but perhaps Sarah’s response was the safer one in that sudden situation.

Back at the base, I go for a hike. I learn about TFI’s money problems from Sarah, so we decide to try to get funding from the Student Association. We also see a female Blue-crowned Manakin. Admittedly, it is not a male, nor is it a lek, but an awesome find nonetheless. It was particularly astounding as she is very difficult to see due to her fantastic camouflaged green plumage. Perhaps the cryptic coloration of the female is another way to hide the nest. After the hike, we have further lectures on deforestation and go to sleep after a long day.

I go birding today. I see a Stripe-throated Hermit whizzing around some trees. As far as hummingbirds go, it has relatively boring coloration. It is greyish tan.

After breakfast we go to San Isidro. There, I walk around for some time and see the church. The church is built in startling contrast to the one in Tres Piedras. It is much bigger, and although not particularly gilded, very neat and cleanly decorated.

On the way back, I see a medium sized black bird sitting in a tree on the side of the road. The bird has something large and red in its beak. Upon second glance, however, I note that this red item is in fact its beak. It is a Fiery-billed Aracari! I am the only one who noticed him and I have yet another lifer to add to my list

I go on a hike. Today, I actually see the hummer in the nest. It is a Band-tailed Barbthroat. This is another rather drably dressed hummingbird. Further up, just before the bean field trail, I see a crashing of leaves. I catch up and strain to see through the undergrowth to find what may have caused the commotion. From the motion of the leaves, I estimate that it is at most two feet tall. Unfortunately, this does not limit the list. It could be a coati, a Capuchin monkey (they are the only species of monkey here to run across the ground. This is unlikely, however, as they would much prefer to go through the trees of the canopy.), or perhaps one of the small cats here. Lauren saw a jagarundi a few days back, and there are also marguay and ocelots in the region. However, I cannot tell what the creature was.

Soon after my encounter, I head back down for lecture regarding deforestation. Deforestation here is a particularly disastrous because it has a plethora of effects, from loss of habitat, to increased erosion, to loss of fixed carbon. Following dinner, we open the biochar pit. To our surprise there is nothing but ash. Our fire burned so hotly and for so long that it burned all of the wood. It must have received more air when, during last night’s storm, part of the pit’s covering collapsed, creating an opening. At any rate, Martin and I are still rather pleased with ourselves. We may not have created charcoal, but we did make a fire that survived two full nights of rainforest storms.

Costa Rica Journal


Well folks, if you were wondering where I have been for the past month, let me clear that up.  I have been in Costa Rica for an internship/tropical ecology class/field work.  So, although I haven’t posted in quite a while, I think I can make it up to all of you by posting my experiences from my journal here.  I will add my pictures to that in order to show you the fantastic place I stayed and the wonderful ecosystem with which I fell in love.  Starting tomorrow, right here, I will post a day from the trip each day.  If you have been following this blog for long enough, then perhaps you remember my virtual trips through Africa and South America.  Well, this will be much like that, except it really happened.  I only hope I can convey, to one degree or another, just how spectacular this place is.  I hope you enjoy it.

Also, just let me know what you think of the new setup and tell me if you prefer this one or the old one.

The new one is up now and here is a picture of the old one.
