Wrenthrush

The wrenthrush (Zeledonia coronata) or zeledonia, is a unique species of nine-primaried oscine, endemic to the Talamancan montane forests. == Taxonomy and systematics == The wrenthrush is the only member of its genus and family. Despite its name, it is neither a wren (Troglodytidae) nor a thrush (Turdidae), and is not closely related to either of those families. Over time it has been treated as related to thrushes and Old World flycatchers (Muscicapidae) and by the late 20th century was placed as a member of the New World warblers (Parulidae). Phylogenetic studies of nuclear and mitochondrial DNA after that date led to reassessment of several genera and in 2017 the wrenthrush was moved to its own family. The exact placement of that family is still not firmly settled, but most taxonomic systems agree that it is closely related to the spindalises (Spindalidae), Cuban warblers (Teretistridae), and several other small Caribbean families, and more distantly related to New World sparrows (Passerellidae) and New World blackbirds (Icteridae). BirdLife International's Handbook of the Birds of the World places it much closer to the New World sparrows and blackbirds than do the others. The wrenthrush's genus name commemorates José Castulo Zeledón, a Costa Rican…
