Day of the Oropendolas

First off, we've been extremely delinquent in responding to the people's will: you told us to get ourselves to Brazil, and to Brazil we go. In June, we're heading back to the Pantanal with our friend/guide extraordinaire Ailton Lara to the Pantanal Jaguar Camp. Ailton's so sought-after that we're competing with the crew of National Geographic for his time. We should clarify, since we've gotten a lot of questions, that we're not extending our six-month time away from home. This will be a side-trip, after which we return to Costa Rica before coming home as planned in mid-July.

In the meantime, we're very content with the hordes of birds we've been getting in our nets at Kekoldi. Today, we were stunned to get half a flock of chestnut-headed oropendolas. These are fairly large birds that don't usually come low enough to get caught in the nets, but we were on a ridgeline today that they kept crossing while foraging. We banded a total of seven, but a bunch more escaped from the nets as we approached. One of the nets actually collapsed under the combined weight.

Check out the enormous beak. It hurts, but not as much as the claws.

While we had the birds, their flockmates stayed very close to our site, calling for their friends in concerned voices. As we let them go, they went to join the others and had insane oropendola conversations about the ordeal. For those who haven't heard an oropendola before, you really should.

Photo Tour: Birding, Banding, and...

Aaron, Duaro, and Mike examining dusky-capped flycatcher
The last two weeks have been full of bird banding. We've stuffed our heads full of plenty of new species and are trying to remember the six-letter codes for each to speed up our data entry (example: long-billed hermit, a hummingbird, has Latin name Phaethornis longirostris, which becomes PHALON in our data sheet). There are also plenty of different criteria for determining the age and sex of birds, varying by species.

Red-capped manakin: fully adult males look like this,
but younger males and females look alike and are olive-colored
Some of our birds are ultra-tiny hummingbirds, but occasionally, too large to band, like this broad-winged hawk. Getting it out of the net was a two-person effort.




Our prettiest birds to date have included this green honeycreeper and golden-hooded tanager:



Our teenage Tico banders are awesome. How many US teens can rattle off dozens of Latin bird names? These guys also have a great sense of humor.

What kind of book has these four teenage guys so engrossed?
Hummingbirds of Costa Rica, of course!
Sometimes, we find cool things like this caterpillar
when we're out working
When we're resting, we're often reading at the station and staking out the birds that visit the fruiting and flowering trees. Still trying to get a great shot of the keel-billed toucan, which, in spite of its size, is very shy. All the ones we've seen take off once they realize they're being watched.


Instead of the nesting woodpeckers we were hoping to photograph,
this lizard was kind enough to pose
Every week to week and a half, we get a little time off. On our last free weekend, we went to Parque Nacional Braulio Carrillo. Very beautiful, but we felt like the trails stayed much too close to the main highway; we could hear traffic as we were walking.


Right now, we're in Parque Nacional Cahuita, and spent an enjoyable morning hiking...more on that to follow.

Life in the Hills

Our new temporary life in Costa Rica is off to a good start. The hills are still turning us into red-faced, drenched versions of ourselves, but we think we’re having a slightly easier time of it now than a week ago.

The Kekoldi station entrance is about 10 minutes by bus from Puerto Viejo de Talamanca. From the entrance, we hike up a forest path about 30 minutes to get to the station. There are various trails around the forest, most of which we still don’t know. In fact, one of our first days of bird banding here, we accidentally took the wrong trail in the early morning hours on our way to meet the team, and had to backtrack up an even steeper part of the hill than our usual route. We haven’t made that mistake again!

Emily with Keswar (left) and Duaro (right). Most of our banding
stations are in the field and we sit on a tarp. 

Here, we have a table!
Our team consists of Daniel Martinez, who’s been leading the operation since 2006, Bribri brothers Duaro and Keswar, Aaron, who’s just joined us from Kentucky/North Carolina, and us. They’re all very nice and intelligent, and the three of us Americans attempt to converse in Spanish as much as possible, only switching to English when we’re not sure of a word or phrase. I think our Spanish is improving, but it can be exhausting trying to think in another language all day.

Birds here have continued to be interesting, and for mammals, so far we’ve seen sloths galore, white-faced capuchins, and an olingo (which only Mike has seen so far, even though it apparently comes by the station every night). Favorite birds since last time, seen, not netted: a pair of spectacled owls during the day, great potoo that hangs out by the station, white-collared manakins that have leks all over, and woodpeckers of various persuasions including cinnamon, pale-billed, and black-cheeked. Oh, and spring raptor migration is happening! On any given day, we’ll see groups of hundreds of them—mostly turkey vultures, Swainson’s hawks, and broadwinged hawks—flying north, just over the span of a few minutes.

A few days ago, we had time off and went to nearby Manzanillo for hiking (both of us), snorkeling (Emily) and kayaking (Mike). The water here is a great temperature, and the reef is right off the shore—though the best reef is probably further out than swimming distance. There are boat trips for snorkeling, but we’re trying to be good about our budget.

Speaking of budget, here’s a question for you all: once we’re done with our program here in June, should we spring for a trip back to Brazil before we return to the states in July? We went to the Pantanal several years ago and had to purchase expensive 5-year visas, which expire in another few years. But since we’re in this part of the world already, maybe it makes sense to return on this trip, before we go home and “settle down” more permanently. It’s not cheap or super-close to get there, and the Pantanal and Amazon require guided tours and stays at fairly nice places. This could be our last chance for quite a while, though, and we’d still really like to see some big cats (and small cats!) and the ridiculous giant anteater. Last time, we saw Brazilian tapir, birds galore, and other neat creatures. But what if we return home jobless? Maybe we’ll regret the additional expense. The economy still seems pretty slow. Check out our poll on the right and tell us what you think. Other suggestions of favorite places with excellent wildlife viewing opportunities that come at a reasonable price?

Last days in Peru, first days in Costa Rica

Our last few days in Lima, camera aside, were enjoyable. We stayed with Narda and Alexis’s family again, saw Chris of FFT and met his family, and had a few great outings. Narda and Alexis took us to Pantanos de Villa, the only reserve within Lima, and we had an awesome time birdwatching with them. We searched in vain for burrowing owls—found a nest, but owls were hidden—but did find the hilarious Peruvian thick-knee, one of the silliest-looking birds we’ve ever seen.

Chris helped us set up an outing with his friend Guillermo, a guide in Lima, to the Lomas de Lachay, about 100 km outside central Lima. It’s full of rolling hills that are apparently cloud-forest-like in the wet season, but were more desert-like when we went. We still saw a bunch of neat birds, including two pairs of burrowing owls and the elusive Andean tinamou. Apparently, the entire countryside in the area outside the reserve used to be similar habitat before ranchers and loggers pretty much turned it into the desert it is now. Even in the reserve, in a less-used entrance, there was a squatter illegally grazing his goats. The park service must be either powerless or turning a blind eye. However, they are trying to reforest the area inside the reserve, collecting seed pods for planting, which was neat to see.

Kekoldi research station
When we arrived in San Jose, we stayed the first day at Hotel Kekoldi (same name, no relation to the indigenous reserve where we are now). Lots of errands including doctor visit (Emily: just finished the resulting course of anti-parasitics and anti-bacterials…stomach in slightly better shape), haircut (Mike), bus ticket purchase, and eating. We both agreed that San Jose has really grown on us since our first visit in 2004. It’s walkable, pretty safe, and has some attractive parks.

The Kekoldi Indigineous Reserve, where we’ll be doing bird research for a while, has a nice research center run by the incredibly hospitable Sebastian, Maritza, and their Bribri family. They cook tasty food and are eager for us to have a good time. We need to revise our thoughts that Peru would be hotter than Costa Rica, though: it’s been a lot sunnier and more scorching some days here. Mosquitoes are still a problem, and there are leishmaniasis-carrying sandflies, too. Hoping we’ll stay healthy!

The place is super-hilly, too, and makes us feel out of shape and sweaty. Hopefully we’ll get used to it!

Birds from the first few days of mist-netting and banding were very cool: a tiny hawk (that’s really what it’s called), white-whiskered puffbird, tanagers, woodcreepers, and tons of hummingbirds, which thankfully have all flown off okay.

We're actually pretty worn out...this trip is no relaxing vacation! But we're doing well, and looking forward to the next few months.

Fauna... forever!

The past month has been an experience like none we’ve ever had. Sure, there’s been plenty of rain and we haven’t been able to go out as much as we’d originally planned, but we’ve also been out in the forest plenty and have gotten to see some fantastic things. Here are some highlights (and a few lowlights) since we last wrote:

Way back on Valentine’s Day, we were in town. Here’s how we spent the day: Mike – at the house with a stomach bug; Emily – machete-wielding with the group to clear the trails of a few trees at Anaconda Lodge. ¡Que romantico! The night before, the group had gone to La Balsa, an open-air disco next to the river, a pretty neat place. Our last day in town was spent at the Amazon Shelter, building and improving enclosures for the animals they take in. One owl monkey in particular took a special liking to Emily and had to be pried off her shoulders. Dave's picture of it appears in a cool interview with Fauna Forever leader Chris Kirkby.

Next came Casa ITA, run by Reserva Amazonica on the Madre de Dios river, which has all the access to RA’s trails, but with considerably more rustic accommodations a mile or so away. The trails themselves were a bit worse for wear because of four straight days of rain while we were there, and more before we’d arrived, but among other things, we saw a sleepy porcupine at eye level a few feet away, saddle-backed tamarins (cute, tiny monkeys), and a quick glimpse of peccary (wild, hairy forest pigs). We also found a fantastic leaf-mimic praying mantis. The insects in general are out of this world.

Our mist nets were in between thigh-deep pools of water, which we’d been dreading, but which didn’t turn out to feel as horrible as we expected. Especially since one of the birds we netted was the very large, very cute black-fronted nunbird, one of Emily’s favorites.

The best part about Casa ITA / Reserva was the canopy walkway, which we took advantage of with Naun whenever possible. There were some truly amazing birds, and the view of the forest was incredible.

Because our next destination unexpectedly closed for a month, we ended up back at Sachavacayoc Center for our last part of the program, which was fine with us. We were able to go out bird netting/banding most days, and the herpetofauna (snakes, lizards, frogs) team took a lot of night walks and other excursions.

Trails were in overall better shape, and we saw tons of mammal tracks including tapir, deer, and peccary. We briefly saw some peccary through heavy foliage, and Naun—lucky Naun—actually saw a tapir at the mist nets, then, later in the same day, an ocelot! We were just far enough behind to miss out. Years waiting to see an ocelot while traveling in the tropics: 7. Moral: walk right on your leader/guide’s heels.

What we did see, in the morning before we came back to town, is the rather rare harpy eagle. It flew across the field at Sachavacayoc, landed in a tree for long enough to get a good look, then took off again before we could call the others. Think about a giant bird…maybe a red-tailed hawk for those of you back home in the States. Now double or triple it in size and give it a cool crest (with a color change to shades of gray). Awesome.

Now, we're in Lima for a few days. Then, time for Costa Rica. More to follow. Anyone have any favorite animals you’d like us to try to see for you?

Many thanks to Dave, Chris, Naun, Brian, James, and Tania for making our time with Fauna Forever Tambopata memorable and enjoyable!
