Nombre en español: Mirla Caripelada
Nombre en inglés: Spectacled Thrush
Nombre científico: Turdus nudigenis
Familia: Turdidae
La paraulata ojos de candil (Turdus nudigenis) es un ave residente y que se reproduce en las Antillas Menores y en América del Sur, desde Colombia y Venezuela hacia el sur, y el norte de Brasil.
El Tordo de Ecuador, que es muy similar, aunque alopátrico, anteriormente era considerado una subespecie de la paraulata ojos de candil y se lo denominaba Turdus nudigenis maculirostris; actualmente se lo cataloga como una especie separada y se lo denomina Turdus maculirostris; posee un anillo ocular algo más estrecho y solo habita en el bosque y matorrales del oeste de Ecuador y noroeste del Perú.
Descripción
La paraulata ojos de candil mide 23 a 24 cm de largo y pesa unos 60 g. Su dorso es de un color verde oliva con tono marrón, siendo este color más pálido en el pecho; el cogote es marrón con rayas blancas, y el vientre es blanquecino. Posee un prominente anillo de color amarillo alrededor de los ojos, lo que le da su nombre científico y su nombre vulgar.
Hay dos subespecies con definiciones un tanto pobres, las cuales se diferencian principalmente en el tono del plumaje. Los animales de distinto sexo son similares, pero las aves jóvenes poseen manchas en el dorso y el pecho, y el anillo del ojo es algo más delgado.
Su canto es un gorjeo musical, más lento y de tono más grave que el del zorzal cacao, aunque también produce un llamado similar al de un gato (queeoow), y si está alerta emite un kereel.
Ecología
El hábitat de este gran túrdido son los claros del bosque, pastizales y cultivos. El Paralauta ojos de candil se alimenta, principalmente a nivel del suelo o en su proximidad, de frutos, bayas y algunos insectos y lombrices de tierra. Es una especie tímida, aunque en Trinidad y Tobago es más osada, y se aproxima a los comederos y toma comida de las mesas.
Su nido es una pequeña cesta abultada formada con ramas en la zona baja de un árbol. Los tres o cuatro huevos que pone son de color azul oscuro con manchas pequeñas rojizas y solo son incubados por la hembra.
Spectacled thrush
The spectacled thrush, bare-eyed thrush, or yellow-eyed thrush (Turdus nudigenis), is a resident breeding bird in the Lesser Antilles and in South America from Colombia and Venezuela south and east to northern Brazil. In Trinidad and Tobago, this thrush is also known as big-eye grieve.
The similar but allopatric Ecuadorian thrush was formerly considered a subspecies of the bare-eyed thrush and named T. n. maculirostris; it is now normally considered as a separate species T. maculirostris. It has a narrower eyering and is only found in forest and woodland in western Ecuador and northwestern Peru.
Description
The spectacled thrush is 23–24 cm long and weighs 60 g. It is plain olive-brown above and paler brown below. The throat is brown-streaked off-white, and the lower belly is whitish. It has a prominent yellow eye ring which gives rise to its English and scientific names.
There are two poorly defined subspecies, differing mainly in the darkness of the plumage. Sexes are similar, but young birds are flecked above and spotted below, and have a thinner eye ring.
The song is a musical warble, slower and lower pitched than that of the cocoa thrush (T. fumigatus), and it also produces a cat-like queeoow call and, when uncomfortable, emits a {[not a typo|kereel}}.
Ecology
The habitat of this large thrush is open woodland, forest clearings and cultivation. The bare-eyed thrush mainly feeds on or near the ground on fruit, berries and some insects and earthworms. It is a shy species, but on Trinidad and Tobago it is much tamer, and will come to feeders and take food from tables.
The nest is a lined bulky cup of twigs low in a tree. The two to three reddish-blotched deep-blue eggs are incubated by the female alone.
Also known as the Bare-eyed Thrush, this member of the genus Turdus is a reasonably common inhabitant of wooded lowlands from eastern Colombia to the Guianas and northern Brazil, as well as in the Lesser Antilles as far north as Guadeloupe. In the past, this species was sometimes considered conspecific with either the Ecuadorian Thrush (Turdus maculirostris) or the Clay-colored Thrush (Turdus grayi), but separation from them both is now well accepted in the literature. The sexes are alike in this generally brown-colored thrush, which is slightly paler below, with an obvious white ventral region and throat, the latter streaked darker, and a large, bulbous-looking, orange-yellow eye-ring. The bill is yellow and the legs are olive-colored. The Spectacled Thrush is principally arboreal, but regularly feeds on the ground, and its diet is relatively catholic.
