Russet-winged Schiffornis

The russet-winged schiffornis, or russet-winged mourner, (Schiffornis stenorhyncha) is a species of Neotropical bird in the family Tityridae, the tityras, becards, and allies. It is found in Colombia, Panama, and Venezuela. == Taxonomy and systematics == The russet-winged schiffornis was originally described as Heteropelma stenorhynchum. However, genus Heteropelma had earlier been established for a wasp and so by the principle of priority the species had to be reassigned. For much of the twentieth century Schiffornis was placed in the manakin family Pipridae and its species were called manakins. Several early twenty-first century studies confirmed the placement of Schiffornis in Tityridae and taxonomic systems made the reassignment. In 1998 the American Ornithological Society was unsure where to place the genus and listed its members as incertae sedis but in 2011 moved them to Tityridae. The russet-winged schiffornis was long treated as a subspecies of Schiffornis turdina, which at the time was called the thrush-like manakin and later called the thrush-like schiffornis. Since at least the late twentieth century taxonomists had suspected that several species were embedded within Schiffornis turdina. Studies published in 2007 and 2011 confirmed that S. turdina was polyphyletic. Following these studies taxonomists separated the russet-winged schiffornis and three…
