Far from home this troupial was welcomed by the Orange-backed Troupials of Costanera. Though today this species is included, it had been photographed last year (left photo) without realizing it was another species. The resemblance is significant. Only the black hood and a difference in size. The Troupial is bigger. Recently these troupials have been split into two different species. The justification was based on the information obtained in areas where these troupials coexist (certain areas in Brasil). It has been observed that they behave as biological species and no hybrids or mixed pairs have been reported. As far as the voices are concerned differences are perceived, but no exhaustive research has been done up to the moment.
