We found the White Hawk one a day as we hiked through the entrance road at Yatama Ecolodge. We went down in search of the Bare-necked Umbrellabird, to no avail. As we were getting close to the lodge, we watched a female Yellow-bellied Sapsucker on a Cecropia tree, which I had seen a few times before. We spend about 10 minutes just watching the bird, and it suddenly went away, so we continued walking to the entrance, when a big white bird flew across the road, and perched on a branch where it started to vocalize. Our theory is that the Sapsucker flew away because she spotted the hawk as it was approaching the area, but we will never really know.
We found the White-lipped Rain Frog as we hiked during the night in search of the Annulated Tree Boa at Yatama Ecolodge, a prime conservation reserve bordering Braulio Carrillo National Park. It has a brownish coloration, which would help it camouflage really well against the ground and the leaf litter which is the usual habitat for Craugastor frogs, however the one we saw was resting on top of a leaf. Both arms and legs are slightly striped, noticeable only when looking from very close. It actually was a pretty common sight in the trails around the reserve, although most frequently heard than seen.
The Rufous-naped Wren is a commonly seen bird close to people’s homes at urban towns in the Central Valley, in Costa Rica; the House Wren is smaller and more common in the countryside, and the Rufous-naped is more colorful, with its black and white pattern on the back and the whitish underside. Compared to that, the House Wren is featureless. Rufous-naped Wrens are very noisy, usually found in pairs or small groups that climb to roofs. I have seen them build their nests under the roof or even in metal doors.
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.
Stripe-tailed Hummingbirds are distinguished from other hummingbirds by its rufous wing patch, although that characteristic is shared with the Blue-tailed (rare in Costa Rica) and Black-bellied Hummingbirds. It has a white vent and tail underside, along with the outer two feathers of the tail being white on the upperside. The male shows a dark blue patch on the throat which continues until the chest. During flight, the wings look almost entirely rufous, with only a lining of green feathers on the shoulders. The female has a white throat and chest. Both sexes resemble the Coppery-headed Emerald, although the latter is smaller.
Bellbirds are very unique birds, not easily confused with any other bird species in Costa Rica. As the name implies, the male has three protuberances on the faced called “wattles”, which by itself puts them in a category of their own. The head and throat are white, with a chestnut body, a color combination that is unlike every other bird in the country. The female is olive, with yellowish underparts that have red stripes; it could be confused with a Flycatcher, however it is a log bigger in size than the Boat-billed Flycatcher. Bellbirds in Costa Rica display altitudinal migration patterns and hence can be seen in coastal areas like Golfito, and mountainous areas like San Ramon. Males are found actively calling during the breeding season, which starts on March and ends by July. Juveniles resemble the females, but would try to sing with varied degrees of success, as they learn from their parents the delicate art.
The White-collared Seedeater is very similar in shape to the common Variable Seedeater, and the male particularly resembles the Pacific race of the latter species. As with most seedeaters, the female is brown, but with a lighter color than other species. The male has a wide white collar around the neck, while the Pacific race of the Variable Seedeater has a thin line that does not join in the back of the neck and shows a black throat. The White-collared has wing bars, which no other seedeater in Costa Rica posses. Both species can be readily found in open pastures, where they share their main habitat and compete for food, specially grass seeds. Seedeaters tend to not gain the attention of most birders, but I believe this is the most beautiful seedeater species that we can see in Costa Rica. This individual stood on the fence wire as we drove through Boca Tapada; the picture was taken from the car window.
The White Ibis is, well… entirely white in plumage. When spotted from a distance it can resemble a Great Egret, Cattle Egret or Snowy Egret, however the pink legs and face, along with the long, skinny downcurved bill is diagnostic. The tips of the wings are black, although that is only visible during flight. The juvenile has brown upperparts, and the neck is striped in brown and white, with gray legs and a darker bill. It is found in ponds and marshes in Guanacaste and the northern area of the country; also along the pacific coast of Costa Rica. Given its habitat, they usually wade in the shallow waters and mudflats, where pick small crustaceans and fish, just like Egrets do.
The Acorn Woodpecker is one of Costa Rica’s largest species, only topped in length by the Lineated and Pale-billed Woodpeckers. The funny-looking pattern on its face earns it the local name “little clown”, with a conspicuous red crown, and a black and yellowish-white mask that cover the face and throat. The iris is almost white, and the bill is black. While the back and wings are entirely black, the chest has black and white streaking, and the belly is white. The female can be identified by a small black patch on the front of the crown, whereas the male’s crown is entirely red. Their inhabit the highlands, particularly Cerro de la Muerte (Buenavista) and Cordillera de Talamanca, where they are very common. Their call display is also very showy when compared with other Costa Rica woodpeckers, swinging their body from one side to the other while giving their calls away.
The Blue-and-white Swallow is very similar to the Mangrove Swallow, given that the Mangrove’s upperparts are green but may look blueish under certain lighting conditions, and they share the white underparts and long black wings and tail. It is distinguished by having black undertail coverts, and the fact that Mangrove Swallows are for the most part encountered in coastal areas, while the Blue-and-White can be found almost anywhere in the country. Like other swallows, they readily perch in cables to rest. They also like to construct their nests in human made structures like roofs.
