Comparative Analysis of the Vocalizations of Hylorchilus Wrens

Analysis of variation in the main song and in other characters of Hylorchilus wrens, together with biogeographic considerations, support the recent suggestion that the genus consists of two species, Sumichrast's Wren (H. sumichrasti) and Nava's Wren (H. navai). The evidence also challenges...

Description
Summary:Analysis of variation in the main song and in other characters of Hylorchilus wrens, together with biogeographic considerations, support the recent suggestion that the genus consists of two species, Sumichrast's Wren (H. sumichrasti) and Nava's Wren (H. navai). The evidence also challenges the proposal that the Canyon Wren (Catherpes mexicanus) is this genus' closest relative. The song characteristics shared by the two separate species of Hylorchilus suggest that the song of their common ancestor included abrupt changes in pitch, pauses between syllables, and frequent use of syllables lasting more than 0.35 sec. These are exactly the opposite of what would be expected if the Canyon Wren were their closest relative (sister-group). It is suggested that the Canyon Wren-like characteristics of the song of one of the species are due to convergence. Thus the closest relative of Hylorchilus wrens remains to be found.
