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.

Likely
About 50% of wildlife watchers report a White-crested Tyrannulet sighting in El Palmar National Park on a given day, based on 164 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 28th most-seen of the 151 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
February, May and July–September
In those months about 60% of wildlife watchers report a White-crested Tyrannulet in El Palmar National Park on a given day, against about 30% in October, the lowest month.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most White-crested Tyrannulet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 10 parks where we can rate White-crested Tyrannulet sightings, El Palmar National Park has the highest daily chance: about 50%. Next come Serra da Canastra National Park (Brazil, about 20%) and Iberá National Park (Argentina, about 20%).
GBIF citizen-science records
It is estimated from how often the White-crested Tyrannulet is recorded against all the birds logged in El Palmar National Park (164 verified sightings from 2019 to 2026), 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.
