Gray-headed elaenia
species of tyrant flycatcher from South and Central America
The grey-headed elaenia or Atlantic grey elaenia (Myiopagis caniceps) is a species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Bolivia, Brazil, and Paraguay.
Taxonomy and systematics
What is now the grey-headed elaenia was originally called the "straw-crested flycatcher" (Tyrannula caniceps). It was later moved into genus Myiopagis and called the grey elaenia. Soon thereafter Myiopagis was merged into genus Elaenia and other taxa were moved from species status to become subspecies of it. The move into Elaenia was reversed in the mid-twentieth century, and Myiopagis was confirmed by genetic analysis to be the grey elaenia's proper genus.
The grey-headed elaenia's further taxonomy is unsettled. BirdLife International's Handbook of the Birds of the World split all but the nominate subspecies M. c. caniceps from it in December 2016, calling the resulting species the Atlantic grey, Choco grey, and Amazonian grey elaenias. The Clements taxonomy recognized the split in November 2022 and the International Ornithological Committee (IOC) followed suit in January 2023.
This brief starts where responsible research should: with the source description of “Gray-headed elaenia” as species of tyrant flycatcher from South and Central America. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of tyrant flycatcher from South and Central America. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 29, 2025. The linked authority identifier is Q905300. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2016, 2022 and 2023.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
