The yellow-headed warbler (Teretistris fernandinae) is one of two species of bird in the Cuban warbler family Teretistridae. It is endemic to western Cuba. The yellow-headed warbler shares its family and genus with the Oriente warbler (T. fornsi). They were originally placed in the New World warblers (Parulidae) but phylogenetic studies of nuclear and mitochondrial DNA led to reassessment of several genera and in 2017 the Cuban warblers were moved to their own family. Their closest relatives are the four members of family Spindalidae, the yellow-breasted chat (Icteria virens), and the New World blackbirds of family Icteridae.
The yellow-headed warbler is monotypic. The yellow-headed warbler is about 13 cm (5.1 in) long and weighs 6 to 18.5 g (0.21 to 0.65 oz). Its entire head is yellow, with an olive tinge on the crown and nape. Its upperparts are gray and its underparts a lighter grayish white.
The yellow-headed warbler is found in far western mainland Cuba, Isla de la Juventud (Isle of Pines), and the nearby Cayo Cantiles. It inhabits all available forest types as long as they have a relatively undisturbed... Wikipedia →

Likely
About 40% of wildlife watchers report a Yellow-headed Warbler sighting in Ciénaga de Zapata on a given day, based on 516 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 32nd most-seen of the 177 birds we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
March
In that month about 50% of wildlife watchers report a Yellow-headed Warbler in Ciénaga de Zapata on a given day, against about 20% in October and November, the lowest months. That is one of Ciénaga de Zapata's driest months, with about 20 mm of rain against 150 mm in June. September has too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Yellow-headed Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Ciénaga de Zapata, in our data
Ciénaga de Zapata is the only park on Wallace's Line with enough records to rate Yellow-headed Warbler sightings: about 40% of wildlife watchers there report one on a given day.
Same family: Parulidae
The closest relatives of the Yellow-headed Warbler that you can see in Ciénaga de Zapata (family Parulidae, New World Warblers) are American Redstart (about 60%), Palm Warbler (about 60%) and Common Yellowthroat (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow-headed Warbler is recorded against all the birds logged in Ciénaga de Zapata (516 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.
