Nombre en inglés: Graceful Black-throated Trogon
Nombre científico: Trogon tenellus
Familia: Trogonidae
El surucuá amarillo (Trogon tenellus) es una especie de ave en la familia Trogonidae.
Distribución física
Se reproduce en tierras bajas del sur de Honduras al oeste de Colombia.
Hábitat y alimentación
Es residente de los niveles bajos de selvas tropicales, prefiere fuerte sombra. Comen insectos y fruta, a veces en vuelo; oportunísticamente utilizan artrópodos, lo que hace visibles a otros predadores como coatimundis (Nasua nasua).
Su pico fuerte y patas débiles reflejan sus hábitos arbóreos y su dieta. Aunque su vuelo es rápido, son renuentes a volar alguna distancia. Típicamente se ubican en perchas y no se mueven.
Descripción física
Muchos surucuas tienen plumajes distintivos entre macho y hembra, con plumas suaves, con frecuencia coloridas.
Es relativamente pequeña la especie: 23-24 cm de largo y pesa 54-57 g, con un bajo cola blanco y tiras negras, un pico amarillo y alas cubiertas vermiculadas con blanco y negro, pero a la distancia parece gris.
El macho tiene cabeza verde, pecho alto y trasero, cara y cogote negro, y vientre dorado amarillo. La hembra de cara, pecho y trasero pardos, cola rojiza y vientre amarillo. Los inmaduros recuerdan al adulto pero más suaves, y los jóvenes machos garganta, pecho y alas marrones.
Canto
El llamado es un krrrrrr, y acompaña con claros chistidos, cuh cuh cuh cuh.
Anidación
Anida entre 1-6 m de altura en una cavidad, con su típica puesta de dos huevos blancos.
Graceful Black-throated Trogon
The black-throated trogon, also known as yellow-bellied trogon, (Trogon rufus) is a near passerine bird in the trogon family, Trogonidae. Although it is also called «yellow-bellied trogon» it is not the only trogon with a yellow belly. It breeds in lowlands from Honduras south to western Colombia.
Taxonomy
The black-throated trogon was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus’s Systema Naturae. He placed it with the other trogons in the genus Trogon and coined the binomial name Trogon rufus. Gmelin based his description on the «Couroucou à queue rousse de Cayenne» that had been described and illustrated in 1779 by the French polymath Comte de Buffon in his Histoire Naturelle des Oiseaux . Buffon’s specimen was a female with brown upperparts that had been collected in Cayenne. The specific epithet rufus is Latin for «red» or «ruddy».

Description
Like most trogons, it has distinctive male and female plumages and with soft colourful feathers. This relatively small species is 23–24 cm long and weighs 54-57 g, with a white undertail with black barring, a yellow bill and wing coverts which are vermiculated with black and white, but appear grey at any distance. The male black-throated trogon has a green head, upper breast and back, black face and throat, and golden yellow belly. The female has a brown head, upper breast and back, rufous upper tail and yellow belly. Immatures resemble the adults but are duller, and young males have a brown throat, breast and wing coverts.
The call is a churring krrrrrr, and the song is a typical trogon series of a few clear whistles, cuh cuh cuh cuh.
Distribution and habitat
It is a resident of the lower levels of damp tropical forests, and prefers the deep shade of the understory. Their broad bills and weak legs reflect their diet and arboreal habits. Although their flight is fast, they are reluctant to fly any distance. They typically perch upright and motionless.
Behavior
Black-throated trogons feed mainly on arthropods as well as some fruit, often taken in flight; they are one of the most insectivorous trogon species of their range. They opportunistically catch arthropods that have been startled by other predators, such as coatis (Nasua spp.).
The black-throated trogon nests 1–6 m (3.3–19.7 ft) high in an unlined shallow cavity, with a typical clutch of two white eggs.
