Sapayoa

The sapayoa or broad-billed sapayoa (Sapayoa aenigma) is a suboscine passerine bird found Colombia, Ecuador, and Panama. == Taxonomy and systematics == As the sapayoa's specific epithet aenigma ("the enigma") implies, its relationships have long been elusive. The sapayoa was formally described by the German ornithologist Ernst Hartert in 1903 under the present binomial name Sapayoa aenigma. It has always been considered a monotypic genus, Sapayoa, and historically regarded as a New World suboscine; in particular, it was assigned to the manakin family (Pipridae). However, the species was listed as incertae sedis (position uncertain) in the Sibley-Ahlquist taxonomy, because "preliminary DNA-DNA hybridization comparisons ... indicate that this species is either a relative of the Old World Eurylaimidae or a sister group of all other Tyrannida, as suggested by earlier biochemical studies .... In any event, it is not a close relative of manakins or any other recent tyrannoid." More recent research suggests that it is not a New World suboscine at all, but an Old World suboscine. In 2004, it was shown that the sapayoa is an outlier to the New World suboscines. In an earlier analysis based on nDNA myoglobin intron 2 and GAPDH intron 11 sequence data, the…
