Resumen:
We report a case of interspecific nest appropriation by the Eared Dove (Zenaida auriculata) on a nest of the Creamy‐bellied Thrush (Turdus amaurochalinus). The usurpation attempt resulted in the death of both nestlings, including a parasitic cowbird, despite forceful attempts by the thrushes to retake their nest and repeated attempts by the dove to feed the nestlings. We believe that the loss of the dove offspring from a nest in a neighboring tree could have triggered this behavior, which may be a hormonal byproduct caused by the recent loss of their own offspring, similar to what has been observed in Emperor Penguins (Aptenodytes fosteri).
