The Buff-rumped Warbler is a small, loud bird of the Caribbean and Pacific lowlands, usually found in close proximity to water streams and rivers, much like the Torrent Tyrannulet does in higher elevations. The places it inhabits are dark, hence it is difficult to see; look for two essential clues: 1) An accelerating high pitched song that seems to come from a water source and 2) a small white patch that swings from one side to the other close to the ground, which is caused by the bird’s habit to swing its tail in such a fashion. It can also be spotted as it flies away rapidly when people approach them.
The Crimson-rumped Toucanet is very similar in body form to the Emerald Toucanet, however there are key differences in their coloration. For a start, the beak of this Colombia species is red instead of black, with a white patch on the very base of the bill. It lacks the big purple patch of feathers on the face, but has a smaller turquoise patch by below the eye. The underparts are lighter green than the upper parts, and there is a small turquoise patch on the belly as well, which is not present on the Emerald. Like most toucans, their presence signals other species that is time to leave, as they will readily predate eggs and hatchlings, and we saw this behavior happen at the feeders in Finca Alejandría, as the feeders would empty whenever this bird approached. Also in true toucan fashion, their overall movement are slow, with spurts of fast activity.
The Flame-rumped Tanager looks pretty much the same as the Passerini’s Tanager that we can see in Costa Rica, except for the male having a yellow rump instead of red, and the female having a yellow belly. It has also being found that some individuals have varying degrees of orange instead of the usual yellow. Not so long ago, a female of this species was spotted in Costa Rica, an indication that its range might be spreading towards our country.
The Scarlet-rumped Tanager is known locally as “Sargento” (Seargent) and “Sangre de Toro” (Bull’s blood), among other names. Previously it was known as the Passerini´s Tanager, being virtually identical to the Cherries Tanager, but only inhabiting the Caribbean, whereas the Cherries was only found in the pacific. In sunlight, the red rump of the male glows strongly, contrasting with the deep black in the eyes and the rest of the body. The female is brownish in coloration, and differs from the Cherries by not having the orange throat. The Juvenile male has the same coloration as the female, however as it morphs into adult plumage, patches of black start to show in the body, giving it kind of a Calico look.
