The Great American Interchange in birds: a phylogenetic perspective with the genus Trogon


We report bilateral gynandromorphy in a White-ruffed Manakin (Corapipo altera) collected near Santa Fe, Panama in 2004. The specimen had an oviduct and ovary on the left side and a single testis on the right. The plumage was phenotypically female on the right side and male on the left. The weight and genetic affinity of the specimen were characteristically female. Both Z and W chromosomes were detected inĀ genetic samples from multiple tissue types and toe pads from both feet. This report is a novel record of gynandromorphy in a suboscine passerine.
