Canto: Andrew Spencer

El tororoí pechiamarillo (Grallaria flavotincta), también denominado tororoi rufoamarillo (en Colombia) o chululú de pecho amarillo, es una especie de ave paseriforme perteneciente al numeroso género Grallaria de la familia Grallariidae, anteriormente incluido en Formicariidae. Es nativo del noroeste de América del Sur.

El tororoi rufoamarillo es el único tororoi en su área con garganta y pecho amarillo pálido uniforme. Es endémico de la vertiente pacífica y se encuentra desde el norte de Antioquia hasta Nariño, en bosque nublado con bastantes pendientes. Es difícil de ver, llama desde percha baja y oculta, a intervalos durante el día. La especie ha sido poco estudiada.

Tamaño y Forma

Mide 18cm de largo. Tiene las partes superiores café rufo intenso uniforme, la garganta y el pecho amarillo pálido gradado a blanquecino en bajo abdomen y los flancos café rufo intenso.

Especies Similares

Es el único tororoi en su área con garganta y pecho amarillo pálido uniforme.

Diferencias Regionales

Se considera una especie monotípica.

Distribución y hábitat

Se ditribuye por la vertiente occidental de los Andes occidentales de Colombia y noroeste de Ecuador (al sur hasta Pichincha).

Hasta 1800m. Se encuentra en la vertiente Pacifica desde el norte de Antioquia hasta Nariño.

Es poco común en el suelo o cerca de él, en hábitats de bosques montanos y sus bordes entre los 1300 y 2350 msnm de altitud.

Se ven en la selva nublada musgosa, en matorrales densos y chusques en sotobosque. Favorece las laderas empinadas y la vecindad con corrientes de agua.

Alimentación

Echa a un lado las hojas con el pico. Escarba e introduce el pico en el lodo suave en busca de lombrices, insectos grandes, otros invertebrados y ranitas.

Reproducción

El nido es una taza abierta voluminosa construido con musgos, frondas, ramitas, raquis de hojas y enredaderas, relleno con racillas oscuras. Se encuentra a menos de 2 m de altura sobre el suelo apoyado en el tronco de un árbol. La hembra ponde dos hueos turquesas ligeramente manchados.

Comportamiento

Es difícil de ver, llama desde percha baja y oculta, a intervalos durante el día. No se une a bandadas mixtas.

Yellow-breasted antpitta

The yellow-breasted antpitta (Grallaria flavotincta) is a species of bird in the family Grallariidae.

It is found in Colombia and Ecuador.

Its natural habitat is subtropical or tropical moist montane forest.

This rather simply, yet attractively plumaged antpitta is uniform warm chestnut or rufous-brown above, with pale yellow underparts. Yellow-breasted Antpitta can appear bold and confident, but like most antpittas it is not easily seen, even when using playback or whistled imitations of its song. Yellow-breasted Antpitta occurs over the Pacific slope of the Andes from Colombia to northwest Ecuador, where it inhabits humid montane forests at 1200–2350 m. Yellow-breasted Antpitta appears to favor ravines and gullies inside mature forest, but there have been no quantitative studies of its habitat preferences. It currently is not considered to be globally threatened, but its conservation status perhaps should be re-evaluated. Only one nest has been described and there is almost nothing known of its diet or general behavior. This account provides novel reproductive information and the first description of juvenile plumage of Yellow-breasted Antpitta.

Related Species

Described as Grallaria flavotincta P. L. Sclater, 1877. Ibis, vol. 19: 445. The type locality is «near» Frontino, Antioquia, Colombia.

Yellow-breasted Antpitta was recognized as a monotypic species by early authors (e.g. Cory and Hellmayr 1924), but later was classified as a subspecies of Grallaria hypoleuca (White-bellied Antpitta) by many authorities (e.g. Peters 1951, Meyer de Schauensee 1950, 1970). Based on its different plumage, slightly different song, and allopatric distribution, however, most modern treatments consider it a full species (Hilty and Brown 1986, Ridgely and Tudor 1994, Ridgely and Greenfield 2001, Krabbe and Schulenberg 2003, McMullan et al. 2010). Yellow-breasted Antpitta is closely related to, and probably forms a superspecies with, Red-and-white Antpitta (Grallaria erythroleuca), Bay Antpitta (Grallaria capitalis), Rusty-tinged Antpitta (Grallaria przewalskii), and Grallaria hypoleuca (Lowery and O’Neil 1969, Parker and O’Neil 1980, Krabbe and Schulenberg 2003).

Distribution

Yellow-breasted Antpitta is resident on the Pacific slope of the Andes of Colombia and northwestern Ecuador, at elevations of 1200-2350 m.

Confined to the Americas.

Habitat

Yellow-breasted Antpittas prefer the shady understory of humid montane forests, especially on steep slopes and along riparian areas. Less frequently they are found along forest edges, and appear to be relatively intolerant of habitat disturbance (O’Dea and Whittaker 2007). Krabbe and Schulenberg (2003), however, note that they sometimes can be found in patches of Chusquea bamboo. Within its relatively narrow range, Yellow-breasted Antpitta is found from 1200-2350 m (Hilty and Brown 1986, Stiles 1997, Ridgely and Greenfield 2001, Krabbe and Schulenberg 2003), but in northwestern Ecuador seems more restricted to 1600-2300 m.

Diet and Foraging

There are no published records of prey items taken by Yellow-breasted Antpitta. This species was, however, one of the first species trained to come to worm-feeding stations by Sr. Angel Paz in northwestern Ecuador (Woods et al. 2011). As with other species of Grallaria, worms most likely are an important part of their diet.
