Golden-crowned Flycatcher

The golden-crowned flycatcher (Myiodynastes chrysocephalus) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Bolivia, and Peru. == Taxonomy and systematics == The golden-crowned flycatcher has a complicated taxonomic history. It was originally described as Scaphorhychus chrysocephalus. By the early 1900s it had been reassigned to genus Myiodynastes, which had been erected in 1847. A 1927 publication assigned it five subspecies. One of them (M. c. intermedius) was soon folded into M. c. cinerascens. By at least 1979 M. c. hemichrysus had been separated to form a new species, the golden-bellied flycatcher. A 2016 publication detailed the vocal differences and similarities between the three remaining subspecies of the golden-crowned flycatcher and the golden-bellied flycatcher. Based on that study, by 2020 BirdLife International's Handbook of the Birds of the World moved two subspecies from the golden-crowned to the golden-bellied. The Clements taxonomy followed suit in 2022 and the IOC and both subcommittees of the American Ornithological Society in 2023. The golden-bellied and golden-crowned flycatchers are sister species. These changes left the golden-crowned flycatcher a monotypic species. == Description == The golden-crowned flycatcher is 18.5 to 22 cm (7.3 to 8.7 in) long and…
