Last week, I did some birding around Central America’s biggest ecotone. It’s an area where rainforest meets dry forest meets mangroves and some! It’s such a crossroads of biomes and habitats, I’m not even sure if ecotone is the right term. “Megatone” might be better but “hot birding wonderland” would also work. I’m talking about Carara, the place where the Grand Tarcoles River empties the waters of the Central Valley into the Pacific, where coastal hills capture life giving rains, and where the biodiversity is sort of astonishing.
Given the meeting of so many habitats, the high end species numbers shouldn’t be surprising but, there’s just so much, I can’t help but use superlatives. If you’re headed to the Carara area, get ready for deserved superlative birding. Going birding around there soon? You might find these bits of news and tips helpful.
Tarcoles Bridge Work
Lately, this has been some of the biggest news in Costa Rica. The Tarcoles Bridge, the one where so many thousands of tourists stop to look at crocodiles, is undergoing roadwork. And it’s not pretty. Temporary road closures and changing the two lane bridge to one lane for 24 hours a day on the main and almost only coastal route to Jaco has its consequences.
I was there on the first day of the closures and on the way back from Jaco to Tarcoles, the normally 30 minute drive took four hours.
Yes, you read that right. Four. Complete. Hours. Since then, it’s been similarly bad, sometimes better, sometimes worse. Given that this is also a vital route for commerce, workers, and students, this particular bit of roadwork is throwing a giant wrench into a lot of people’s lives.
With almost no alternatives, if you are headed to and from Jaco or even Manual Antonio, you may be in for a terribly long wait. I suggest trying to see which times are best and probably crossing the bridge at 4 in the morning or so. The current schedule is for the one lane closures to end on March 27th and to happen again from May 4th to May 9th. There will also be some nighttime full closures from March 15 to April 20th. These can happen on any night during those dates from 9 pm to 5 am.
If you plan on visiting Carara National Park, the wait might be a bit less but anything can happen, perhaps more so on weekends. The good thing is that the park is fairly close to the bridge so, if you have to cross back over to the Tarcoles Birding Lodge area, that won’t take as long as driving from Jaco. I suppose another good thing is watching birds while you wait in traffic but, that’s not exactly ideal.
Yellow-billed Cotingas from the Tarcoles Birding Lodge

Now for some good news! While watching from the overlook at the Tarcoles Birding Lodge, I had a quick, distant flyby cotinga one morning and saw two distant males the following morning! This is great news because the Carara population is so dreadfully small, it really could disappear at any time.
Seriously, there might be 5 or fewer birds still occurring in the area. Another positive sign was a recent sighting of a female by an experienced ornithologist (which makes me think he really did see one and not a tityra). What this means for birders visiting the area soon is that you might also see one by scanning for them from the Tarcoles Birding Lodge in the early morning. You’ll see other birds too, maybe even a Gray-headed Kite like the bird pictured at the top of the post (we had one).
You might also get lucky on the Cerro Lodge road, boat tour, or even in the national park but your best bet will be scanning the distant mangroves from the Tarcoles Birding Lodge or maybe Cerro Lodge too or, maybe even another new place…
More Birdy Accommodation in the Area
The new place that could turn up the cotingas as well as lots of other nice birds is a cozy BnB called “Finca Quietud”. This small place just down the Cerro Lodge road is especially suited for couples and single travelers looking for a quiet place with friendly owners, an excellent breakfast, and a nice pool.
It also has an excellent view of a wetland, mangroves, and the sea. I bet the cotingas could be seen from there along with lots of other, more expected species. On a recent visit, one of our highlights was a pair of Spectacled Owls that flew into view before dusk!
Humid Forest Species in Carara

Regarding Carara National Park and vicinity, it seems like the trend of humid forest species becoming rarer is taking place. Unfortunately, climate change has been causing the forest to become drier bit by bit or, at least changing the amount and timing of rains. In any case, various rainforest species seem to have declined and a few have become downright rare, at least in the accessible part of the park.
You can still see a good variety of birds but many are not as common as they used to be and a few have become really tough. The more challenging ones seem to be species that require the wetter forests, birds like Baird’s Trogon (maybe the hardest hit), Orange-collared Manakin, and Golden-naped Woodpecker among some others.
Carara is still worth birding but, to see some birds, if you aren’t birding further south, you may need to look for them higher up on the Bijagual Road or, at Macaw Lodge. It tends to be wetter in those spots (in a good way for birding) but, even there, Baird’s Trogon has become much less common. To look for those birds, especially at Macaw Lodge, local guide Beto Guido is one of the better guides to go with. He birds there quite a bit and recently, even found a rare Agami Heron at the lodge!
Mangrove birding

One of the other birding bonuses around Carara is looking for mangrove species. In Costa Rica, some of those specialties include the endangered Mangrove Hummingbird, Panama Flycatcher, and Mangrove Vireo among a few others. You might get lucky with those species on a mangrove boat trip but even then, they can be easily missed.
The funny thing about those mangrove birds is that they don’t seem to be very common, even in the mangroves! Usually, mangrove sites near Playa Azul are good for them but, recently, despite giving those sites a very good check, they weren’t.
Mangrove specialties seemed oddly absent there and at another spot near Bajamar. One thing I did notice was that those unbirdy mangroves also seemed drier than usual and lacked standing water. I suspect that has something to do with it because it was the only difference compared to past visits that did readily turn up the mangrove specialties.
Also, on a recent visit to mangroves at Mata de Limon, I did see all the mangrove specialties (and heard a Rufous-necked Wood-Rail too!) and those mangroves had lots of standing water. This was a change from another fairly recent visit where they were drier (and turned up far fewer mangrove birds).
I suppose the lesson here is to lower expectations or check other sites if the mangroves look dry and, maybe take that boat trip after all.
That’s all for now, if you visit the Carara area, I hope you catch the bridge traffic at the right moment and see lots of birds. Be ready for hot weather and bring plenty of hydration (no plastic bottles allowed in the national park). As always, I look forward to getting back to that birdy megatone.
On another note, I recently updated the Costa Rica Birds Field Guide app to match most of the recent eBird taxonomic changes and made some other changes too. I’ll write a post about that this upcoming week!
