The Trogons
From the same family as the resplendent quetzal, there are four types of trogons that call the Osa home, especially within the confines of Corcovado National Park. They are the Black-throated trogon, the Slaty-tailed trogon, Baird’s trogon, and the Violaceous trogon.
All four species are of a similar size, growing up to over 9 inches long. All four are also sexually dimorphic (females and males look different), and similar to the resplendent quetzal, nest in hollowed-out tree trunks.
Of the four species in Corcovado, my favorite is the Black-throated trogon for its bright yellow breast, black and white banded tail, and distinct eye-rings. All four species are regularly sighted sitting on horizontal branches in the lower canopy. When nesting, a mated pair will take turns digging out a hollow in a tree and keeping watch for predators. They are vulnerable to raptors and snakes primarily.
Osa Honorable Mentions
I could go on and on listing out my favorite birds on the Osa, but this article would turn into a field guide several pages long. So, instead, I’ll briefly mention some of my other favorites.
Red-Capped Manikin: Unlike many of my other favorites, this is a small bird. But, what it lacks in size, it more than makes up for in interesting behavior. This small blackbird has a brightly colored redhead and is best sighted in Corcovado. What makes it so interesting is it’s the male’s courting ritual when trying to attract a mate. Nicknamed the Michael Jackson Bird, the red-capped manikin males will dance along branches to impress females, executing what can only be described as a perfect bird moonwalk. If you’ve not seen it, look it up on YouTube, Now!
King Vulture: This is a bird I am still working to get a great photo of. Unlike the black vultures and turkey vultures that are so common everywhere in Costa Rica, the king vulture has a bright white upper body with black wing coverts and tail. Excluding condors, it is the largest vulture in the Americas, but what makes this bird so interesting are its bizarre facial colorations. Like other vultures, its head is largely featherless, to make sticking its head into carrion easier. But, the skin consists of shades of red and purple on the head, vivid orange on the neck, and yellow on the throat. It is one bizarre and beautiful bird. Capturing close-ups of its brilliantly colored head is tough though; I’m still working on getting one after three years in Costa Rica.
Great Curassow: Growing to over three and a half feet tall and 11 pounds in weight, the great curassow is a giant amongst rainforest birds. The males are predominantly black with a curly crest of black feathers and a bulbous yellow knob of inflatable skin on its bill. Females are typically barred with black and white bands, but rufous color morphs also exist. What makes this bird so amazing is its stealth and size. Often times when hiking through the jungle, a small twig break will be the only clue to its presence until you look over to see this enormous turkey-sized bird with its iconic curly head crest.
Tortuguero National Park
The latest addition to the BCJ Costa Rica trip is a three-night stint on the Caribbean coast in Tortuguero National Park. Tortuguero holds a special place in the hearts of many Costa Ricans because it was the country’s first national park. It was created in 1975 by then-president Daniel Oduber.
The mythology around the creation of the park goes something like this. International conservationists working in Costa Rica had been lobbying the government for some time to protect crucial ecosystems to Costa Rican wildlife. Throughout most of the 20th century, the country’s primary exports were pineapples, bananas, and wildlife products, such as pelts and crocodile skins. Deforestation was a major issue, as well as destructive commercial gold mining. As a result, much of the precious wildlife resources were hanging by a thread.
But, that would all change under Daniel Oduber’s presidency. One night, international conservationists took Oduber to the beaches of what is now Tortuguero National Park to educate him about the devastating effects caused by the poaching of turtle eggs and the killing of nesting sea turtles. While standing on the beach, they noticed a green sea turtle emerge from the surf. But, something was wrong. She was dragging something behind her and was dropping her eggs as she walked, a very abnormal behavior. Upon closer inspection, they discovered that the turtle had been attacked by poachers. They had cut away her plastron (lower shell) to be used in a soup. They then chucked the turtle back into the sea to die a slow agonizing death. But, driven by instinct, the mother turtle continued her journey to her nesting beach. She was dragging her entrails behind her and was dumping her eggs involuntarily.
This so moved Oduber that shortly after this experience he created Tortuguero National Park to protect the nesting beaches of these sea turtles, along with other sea turtle species like leatherbacks, hawksbill, and black sea turtles. This bold decision led to a wave of green legislation that today has resulted in the protection of over 25% of Costa Rica’s landmass. Now, the number one export for Costa Rica is eco-tourism, resulting in the elevation of the country’s economic status and positioning it at the top of Central American countries in terms of economy and political stability.
In 1975, the park primarily consisted of nesting beaches. But, over the years it has been expanded to include the adjacent rainforest and the complex system of canals and rivers that run through it. The name Tortuguero actually means turtle hunter.
Trips through the Tortuguero rainforest are primarily done from a boat, which makes exploring huge swaths of wilderness efficient and easy. Tortuguero is home to an enormous range of wildlife, from tapir and jaguar, monkeys, sloth, and a huge range of marine and tropical birds. Let’s get to the birds!
