Description The Channel-billed Toucan (Ramphastos vitellinus ariel) is an omnivorous bird that eventually is nest-robbers. Several birdsongs display anti-predatory strategies such as attacks and mobbing calls to face this kind of predators. This note reports a predatory event of one Channel-billed Toucan upon eggs of Pale-breasted Thrush (Turdus leucomelas), and describe the anti-predatory behavior, principally alert and mobbing calls of the thrush. Even though the Pale-breasted Thrush displayed the anti-predatory behaviors to harass the toucan, the egg predation was not avoided. Although the predation upon eggs by Ramphastos vitellinus has been reported several times, the majority of reports lacks of identity of the bird species affected, this being the first confirmed record in Turdus leucomelas.
El Tucán de Ariel (Ramphastos vitellinus ariel) es un ave omnívora, que eventualmente es ladrona de nidos. Varias aves paseriformes muestran estrategias antidepredatorias, tales como ataques y llamadas de acoso para enfrentarse a este tipo de depredadores. Esta nota reporta un evento de depredación de un tucán de Ariel sobre huevos de la mirla pechi pálida (Turdus leucomelas), y describe el comportamiento antipredador, principalmente el relacionado con el las llamadas de alerta y de acoso de la mirla. A pesar, que la mirla pechi pálida mostró un comportamiento antidepredatorio acosando al tucán, no se evitó la depredación de los huevos. Aunque la depredación de huevos por parte del Ramphastos vitellinus ha sido reportada varias veces, la mayoría de los reportes carecen de la identidad de la especie de ave afectada, siendo este el primer registro confirmado en Turdus leucomelas.
