Bird Species That Will Influence Your Osa Experience

Amidst the well-defined world of Osa Peninsula birding, there are a few feathered wonders that leave an indelible mark on visitors to this extraordinary region. Let us introduce you to some of these unforgettable avian delights that grace this diverse and captivating area.


Scarlet Macaw

Scarlet Macaw Cleaning
The Scarlet Macaw EFFECT

Hearing these colourful birds before you see them can lead you to question your eye-sight. And with a flash of brilliant red, blue and yellow, with a loud raucous squawk, you know you are in the rainforest.

In Costa Rica, there are an estimated 1,500 Scarlet Macaws and when you are here on the Osa Peninsula you would think most of them are flying overhead. They can live until 60 years of age and they mate for life.


Fiery-billed Aracari

Fiery-billed Aracari
The Fiery-billed Aracari EFFECT

Unlike their close cousin, the Collared Aracaris, this stunning toucan is named for its red bill and it has a brightly coloured plumage to go with its intriguing beak. They tend to travel in flocks of around 6 to 10 birds so when you hear their chorus, close your eyes and feel the tropical rainforest imprint on your soul. These sounds will return you to The Osa Rainforest, switch your brain off and give yourself a little bit of a rest.

This medium-sized toucan is found in southern Costa Rica and western Panama and breeds only on the Pacific slopes. 


Red-throated Caracara

Red-Throated Caracara
The Red-throated Caracara

This tropical bird is unmistakable by virtue of its size, social habits, and incessant calls which are often very noisy. It utters a strange raucous carrying call “cowh-cah-cowh” or “ah-ah-ah-aou”. We can also hear a long series of “cow-cow-cow-cacow”. In flight, it gives a throaty “rrrah”. These hypnotic sounds can soothe the soul. 

Groups call out and tend to get closer when humans pass through their territory.



Pootoo bird with baby Osa
The Potoo

The song of Common Potoo is described by many as one of the most hauntingly beautiful sounds of the American tropics. This song consists of up to 8 melancholy and wailing or lamenting descending notes, which start loud and gradually drop-in pitch in sliding steps as it fades in volume…some say its melody resembles a ghost. 

They are sometimes called poor-me-ones, after their haunting calls.


King Vulture

The Osa King Vulture
The King Vulture

The King is the first to eat. They are most often seen soaring high around noon, usually very high in the company of groups of Black Vulture. But it is their colourful head and neck, piercing white eyes, and overall white plumage with black trim to wings and tail, that captures your eyes. Nature definitely went with colour on this creation.

King vultures grow to about 2.5 feet (0.8 meters) tall and can weigh up to 8 pounds (3.7 kilograms), making them the largest New World vulture, except for condors.


Orange-collared Manakin

Orange collared Manakin Osa Peninsula
The Orange-collared Manakin

It is the dance of love as the males attract the females to their party inside the forest with a few rapid movements accompanied by sounds produced by their feathers and vocalizations. The males clean an area of bushes creating a dance floor, where at a high speed they vertically bounce from twig to twig. As they settle down, they collide with their wings generating a hollow sound, like little sticks breaking.

They can be found relatively easily on a rainforest hike with a nature guide.


Turquoise Cotinga

Turquoise Coting
The Turquoise Cotinga

This majestic bird Cotinga, comes from the Tupi (natine brasilians) meaning “bright forest bird”. This is an uncommon bird within its habitat and is recognized from the rattle noise that males make on flight with their wings. Seen perch on tall naked trees in the mature forests of the Osa give this coloured songbird a look of a Christmas decorantion.


Screech Owl

Osa Peninsula screech Owl
The Screech Owl

Although this owl is a common species, it is its sound combined with the Osa rainforest that will make a lasting impression. Screech-owls don’t actually screech. It’s true and yet that was the name they were given. I suppose that sounds better than “tremulous”, “modulating”, or “little hooting” owls.


Black-cheeked Ant-tanager

osa Black-cheeked Tanager
The Black-cheeked Ant-tanager

This little bird can only be found in two places: The Osa Peninsula and around Golfo Dulce. It has been documented nesting between January and March. It builds an open cup nest fairly low in understorey vegetation. All known clutches were of two eggs. The species appears to nest cooperatively, as three adults have been documented attending nestlings.


Mangrove Hummingbird

Osa Mangrove Hummingbird
The Mangrove Hummingbird

This is definitely a gift from nature. Found only in Costa Rica, its beautiful calls have been described as a soft, yet rapid, dit sound given in a descending twitter. Their breeding season usually stretches from October through February.
