The Ornate Hawk-Eagle is one of the most sought-after birds in Costa Rica due to its elegant appearance and striking name. Juveniles are dull brown with white head and belly, while adults have a barred belly, black crest and chestnut sides of the face and throat. Its most flamboyant feature is the big crest that adults have. It also have feathered legs. Its preferred environment is the forest, where it catches a variety of prey, including big arboreal birds like the Great Currasow. It is most usually seen circling high on the sky, where it is difficult to identify in silhouette, however their vocalizations give them away easily.
Most Guans and Chachalacas are big arboreal birds, and can show great agility when jumping from branch to branch on the top of the canopy some 20 or 30 meters above the ground. They perch to eat fruits and also to roost in the night. Most species avoid the ground but come down sometimes in search of fruits and seeds. The Colombian Chahcalaca is found in the Andes Region, having brown coloration but with an scaled look thanks to gray tips of the feathers’ barbs. Their head and beak is gray, and it has a bright red dewlap that is folded and inconspicuous, although it can hang freely and thus be seen clearly when the bird is high in the trees. The legs are also red. While shy of people, this species will come to fruit feeders and stay there undisturbed unless you get too close.
The Red-ruffed Fruitcrow is a large bird belonging to the Cotingidae family. It does resemble a crow in overall body form, but it sports a brilliant red-orange throat and an orange chest and belly that’s very distinctive, even inside the darkness of the forest they inhabit. Although arboreal, they do come to the ground to eat fallen fruit. Another endemic bird of Colombia. We saw this bird in Yarumo Blanco SFF, in Pereira, where it is actually abundant and not so afraid of people. It came to ground a few times and seemed to be comfortable with us being around.
The Yellow-bellied Seedeater seems to be a bad name for a species that has a white belly. In a true seedeater fashion, it is found eating seeds from the grass. Its upperside is gray, with a darker head. Its pale bill is short but very strong, enabling it to crack bigger seeds. It shows some dark patches on the flanks and on the separation of throat and chest.
Not to be confused with the Oreotrochilus genus, the Rufous-gaped Hillstar is the only member of the Urochroa genus. It is rather large and streamlined, showing lots of different colors around the body. Its throat is blue to purple, ending on a dark orange malar strip which is very conspicuous and looks like a big smile. The belly is gray but shows blue-green feathers on the sides. The back and head of the body has olive, blue and green hues. A very small white postocular spot finishes the look.
Five species of birds compose the Cinclus genus, all of which have a very unique characteristic: They dive underwater to catch small fish and invertebrates, along with their eggs and larvae. They are most commonly found along river banks and fast flowing streams. Being able to swim underwater, they bear adaptations for this purpose. For instance, their bones are solid to reduce buoyancy, while the feathers are dense and covered in oil that repels water, which has two effects: Maintaining the body dryers, and capturing a small layer of air around its body. The White-capped Dipper in particular is dark gray on the upper side, white on the underside and shows a white cap that goes well with its common name.
The White-browed Spinetail was the only species of Spinetails we ever saw in Colombia. It inhabits the paramo at Nevado del Ruiz, at an altitude of 4,200 meters above sea level. Its body coloration is composed of brown back and head, gray belly, chest and throat, and a gray supercilliary on top of the black eye. With this colors, it might look very dull and uninteresting, however it is an amazing fact for this little bird to withstand the lack of oxygen and low temperatures of this elevation, specially during the night.
The White-bellied Woodstar is among the smallest hummingbirds like most woodstars, however it is colorful and conspicuous. The body is mostly green, with a white collar that joins a white line coming out of the eye. The gorget is metallic purple due to iridescence, so it looks dark sometimes. The black bill is long, thin and just slightly curved down. The vent and belly also show white plumage. It flies in a typical bee fashion, with smooth movements instead of the rapid bursts that larger hummingbirds do.
The Violet-tailed Sylph is part of the Aglaiocercus genus, containing two more species, one of them being the Long-tailed Sylph which we also saw in Colombia during our trip. It has a long tail that glows in purple from the back. Other than that, the bird is mostly green, with flashes of orange on the belly and blue hues on the back. Their bill is relatively short when compared with other hummingbird species on its range. When the outer tail feathers are molted, individuals can be seen with shorter tails, like in the pictures below, since those feathers are precisely the ones that grow very long.
The Violet-bellied Hummingbird is another of the cute hummingbirds we saw in Colombia. Its name is pretty descriptive, since the belly is a deep iridescent purple tone that looks metallic on the right light; on the shadow it looks blue instead. The throat and face also glow in light green sometimes, other times it looks dark green along with the back of the head. It has a long and thin black bill that’s used like most hummingbird to extract nectar from the deep cavities of flowers in Colombia. I saw this individual while walking down from Doña Dora’s restaurant. It was doing its early morning stretching routine.
