This article reports recent sightings of a bilateral gynandromorph of the Green Honeycreeper from Colombia. The bird exhibited male plumage on the right side and female plumage on the left, and it was present for at least 21 months. The study also provides a comprehensive review of previous records of passerine bilateral gynandromorphy.
We report recent sightings, substantiated by color photographs and a short video, of a bilateral gynandromoph of the Green Honeycreeper (Chlorophanes spiza) from Villamaria, in the department of Caldas, Colombia. The bird exhibited typical male plumage on its right side and female plumage on the left. It was present for at least 21 months, and its behavior largely matched that of other wild Green Honeycreepers, although it often waited until they were gone before feeding on fruit that was put out daily by the property owners. We provide a comprehensive list and review of previous records of passerine bilateral gynandromorphy, noting which sex's plumage occurred on the left side. We observe that female plumage is possible on either side, supporting the double-fertilization model of bilateral gynandromorphy. RESUMEN. Reportamos avistamientos recientes, corroborados por fotografias a color y un video corto, de una ginandromorfia bilateral de Chlorophanes spiza en Villamaria, departamento de Caldas, Colombia. El ave presentaba un plumaje tipico de macho en el lado derecho y de hembra en el izquierdo. Estuvo presente durante al menos 21 meses, y su comportamiento coincidia en gran medida con el de otros C. spiza silvestres, aunque a menudo esperaba a que se fueran para alimentarse de la fruta que los propietarios de la finca ponian a diario. Proporcionamos una lista exhaustiva y una revision de los registros anteriores de ginandromorfia bilateral de paseriformes, senalando el plumaje de que sexo se produjo en el lado izquierdo. Observamos que el plumaje femenino es posible en ambos lados, conclusion que apoya el modelo de doble fecundacion de la ginandromorfia bilateral.
