The scarlet flycatcher or austral vermilion flycatcher (Pyrocephalus rubinus) is a passerine bird in the family Tyrannidae, the tyrant flycatchers.{{cite web |url=https://www.worldbirdnames.org/new/bow/flycatchers/ |title=Tyrant flycatchers |website=IOC World Bird List |version =v 15.1 | editor1-last=Gill | editor1-first=Frank | editor1-link=Frank Gill (ornithologist) | editor2-last=Donsker | editor2-first=David | editor3-last=Rasmussen | editor3-first=Pamela | editor3-link=Pamela Rasmussen |date=March 2025 |access-date=March 3, 2025 }} It is found in Argentina, Bolivia, Brazil, Colombia, Ecuador, Paraguay, Peru, and Uruguay.Clements, J.

Taxonomy and systematics

The scarlet flycatcher was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1779 in his Histoire Naturelle des Oiseaux.{{ cite book | last=Buffon | first=Georges-Louis Leclerc de | author-link=Georges-Louis Leclerc, Comte de Buffon | year=1779 | title=Histoire Naturelle des Oiseaux | volume=8 | place=Paris | publisher=De L'Imprimerie Royale | pages=351–352 | chapter=Le rubin ou gobe-mouche rouge huppé de la Rivière des Amazones | language=fr | chapter-url=https://biodiversitylibrary.org/page/42286856 }} The bird was also illustrated in a hand-colored plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text.{{ cite book | last1=Buffon | first1=Georges-Louis Leclerc de | author1-link=Georges-Louis Leclerc, Comte de Buffon | last2=Martinet | first2=François-Nicolas | author2-link=François-Nicolas Martinet | last3=Daubenton | first3=Edme-Louis | author3-link=Edme-Louis Daubenton | last4=Daubenton | first4=Louis-Jean-Marie | author4-link=Louis-Jean-Marie Daubenton | year=1765–1783 | chapter=Gobe-mouche rouge hupé | title=Planches Enluminées D'Histoire Naturelle | volume=7 | place=Paris | publisher=De L'Imprimerie Royale | at=Plate 675 Fig. 2 | chapter-url=https://biodiversitylibrary.org/page/35219175 }} Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Muscicapa rubinus in his catalogue of the Planches Enluminées.{{cite book | last=Boddaert | first=Pieter | author-link=Pieter Boddaert | year=1783 | title=Table des planches enluminéez d'histoire naturelle de M.

The further taxonomy of the scarlet flycatcher is unsettled. It was long considered to be the nominate subspecies of the vermilion flycatcher sensu lato. As of early 2025 the North and South American Classification Committees of the American Ornithological Society (AOS), the Clements taxonomy, and BirdLife International's Handbook of the Birds of the World (HBW) continue this classification, though HBW calls the species the common vermilion flycatcher.Chesser, R.

Their lores and ear coverts are dark grayish brown and form a "mask". Their nape, upperparts, and tail are blackish and their rump blackish brown. Their wings are blackish with paler edges on the coverts and tertials. The lower part of their face, their throat, and their underparts are a slightly lighter shade of poppy red than the crown, with sometimes an orangey tinge.

Distribution and habitat

The scarlet flycatcher is found over the course of the year from southeastern Colombia east across central Brazil and south from there through eastern Ecuador, eastern Peru, eastern Bolivia, and southern Brazil into northern Argentina, Paraguay, and Uruguay. (See the Movement section for details.) It inhabits semi-open to open landscapes such as open woodland, the edges of denser woodlands, pastures with scattered trees, and agricultural areas.

Behavior

=Movement=

The scarlet flycatcher is highly migratory. It is a year-round resident from eastern Bolivia and far northern Argentina east across Paraguay and southern Brazil. It also breeds further south through Uruguay and Argentina to about Río Negro Province. In the austral winter it vacates the southern breeding range. From there and from within the year-round range it migrates north into most of Amazonian Brazil and Amazonian Peru, Ecuador, and Colombia.

=Feeding=

The scarlet flycatcher's diet and foraging behavior are not known in detail. It feeds mostly on insects caught in mid-air with sallies from a perch ("hawking") and also from the ground.

=Breeding=

Nothing is known about the scarlet flycatcher's breeding biology. Almost all of the breeding data from the widespread vermilion flycatcher sensu lato are from Arizona.

{{birdsong|url=https://xeno-canto.org/species/Pyrocephalus-rubinus |species=the scarlet flycatcher}}

=Vocalization=

The scarlet flycatcher's song is an "extr. high tic-tic-psiieh" whose last part may be upslurred, and its call is an "extr. high psi".

Status

The IUCN follows HBW taxonomy and so has not assessed the scarlet flycatcher separately from the vermilion flycatcher.{{cite iucn |author=BirdLife International. |year=2021 |title=Common Vermilion Flycatcher Pyrocephalus rubinus |volume=2021 |page=e.T103682912A187307157 |doi=10.2305/IUCN.UK.2021-3.RLTS.T103682912A187307157.en |access-date=16 April 2025}}
