PY - 2004/01/01 Y2 - 2024/03/28 TI - Geographic variation in the rosy thrush-tanager (rhodinocichla rosea) complex of mesoamerica (aves: passeriformes) JF - Biota Neotropica JA - Biota Neotrop. VL - 4 IS - 2 SE - Short Communications DO - UR - //www.biotaneotropica.org.br/BN/article/view/1581 SP - AB - Patterns of differentiation and geographic variation among populations of the Rhodinocichla complex are described. We document the existence of a heretofore unreported population in the vicinity of Acapulco, Guerrero, Mexico. The species occurs in 4-6 allopatric populations, each of which has unique characters that make it diagnosable. We recommend that the complex be considered a single biological species, but at least five phylogenetic species. ER -
