Description Anomalous plumage colourations are reported for three species of non-passerine birds from Paraguay, Limpkin (Aramaus guarauna; Aramidae), Nanday Parakeet (Nandayus nenday; Psittacidae), and the Little Woodpecker (Veniliornis passerinus; Picidae). A leucistic Limpkin is the first published report of a colour anomaly for the family Aramidae. The colour aberration in N. nenday is hypothesised to be a result of an excess of red psittacofulvin pigments, which are unique to the Psittacidae. Although the mechanisms causing this colour aberration remain unknown, we suggest the term psittacofulvism for the phenotypic effect observed.
Se reportan anomalías en la coloración de tres aves no passeriformes del Paraguay, caraú Aramus guarauna (Aramidae), ñanday Nandayus nenday (Psittacidae) y carpinterito oliváceo Veniliornis passerinus (Picidae). Un caraú leucístico es el primer reporte publicado de coloración anómala en Aramidae. La presencia de coloración aberrante en Nandayus se hipotetiza como resultado de un exceso de pigmentos psittacofulvinos rojos, únicos a los Psittacidae. Aunque el mecanismo causante de esta aberración de color sigue siendo desconocido, sugerimos el término psittacofulvismo para el efecto fenotípico observado.
