The white-crested tyrannulet (Serpophaga subcristata) is a small species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Bolivia, Brazil, Paraguay, and Uruguay. The white-crested tyrannulet was originally described as Sylvia subcristata, thought to be a member of what at the time was the Old World warbler family.
Subspecies S. s. munda was originally described as a full species. BirdLife International's Handbook of the Birds of the World lumped it into the white-crested tyrannulet in 2020. The Clements taxonomy followed suit in 2022 as did the South American Classification Committee of the American Ornithological Society and the International Ornithological Committee in 2023. In addition, what is now Straneck's tyrannulet (S. griseicapilla) was long confused with the white-crested tyrannulet but was eventually recognized as a full species based largely on their very different vocalizations.

GBIF citizen-science records
It is estimated from how often the White-crested Tyrannulet is recorded against all the birds logged in Asuncion (68 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
