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.

Rare
Under 5% of wildlife watchers report a White-crested Tyrannulet sighting in Cordoba on a given day, based on 67 verified sightings from GBIF citizen-science data. It is the 100th most-seen of the 176 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January and September
In those months about 10% of wildlife watchers report a White-crested Tyrannulet in Cordoba on a given day, against under 5% in February–August and October–December, the lowest months.
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.
13th of 14
Of the 14 cities where we can rate White-crested Tyrannulet sightings, Cordoba ranks 13th at under 5%. The best odds are in Buenos Aires (Argentina, about 30%), Rosario (Argentina, about 30%) and Cochabamba (Bolivia, about 20%).
GBIF citizen-science records
It is estimated from how often the White-crested Tyrannulet is recorded against all the birds logged in Cordoba (67 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.
