Atlantic Plain Xenops

The Atlantic plain xenops (Xenops minutus), also known as the white-throated xenops, is a passerine bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina, Brazil, and Paraguay. == Taxonomy and systematics == The Atlantic plain xenops has a complicated taxonomic history. Xenops minutus was long called the "plain xenops" and included 11 subspecies. In 2016 BirdLife International's Handbook of the Birds of the World (HBW) separated X. genibarbis, with 10 of the 11 subspecies, from X. minutus and confusingly called the new species "plain xenops". HBW renamed X. minutus the "white-throated xenops". The International Ornithological Committee (IOC) recognized the split in July 2023 and kept the HBW English names. A study published in 2020 described differences in plumage, vocalizations and DNA among the subspecies of X. genibabis. Based on it and other studies, in August 2024 the IOC further split X. genibarbis into two species, the northern plain xenops (X. mexicanus) and Amazonian plain xenops (X. genibarbis). It renamed X. minutus the Atlantic plain xenops. The South American Classification Committee of the American Ornithological Society (SACC) adopted the three-way split with the IOC English names in September 2024. The Clements taxonomy adopted the same…
