The Kentucky warbler (Geothlypis formosa) is a small species of New World warbler. It is a sluggish and heavy warbler with a short tail, preferring to spend most of its time on or near the ground, except when singing.

Female Kentucky warblers have slightly less black on the sides of their head, and immature birds may have almost no black at all.

Rare
Under 5% of wildlife watchers report a Kentucky Warbler sighting in Cabo Blanco Absolute Nature Reserve on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 168th most-seen of the 241 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
November
In that month about 10% of wildlife watchers report a Kentucky Warbler in Cabo Blanco Absolute Nature Reserve on a given day, against under 5% in December to October, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Kentucky 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.
16th of 38
Of the 38 parks where we can rate Kentucky Warbler sightings, Cabo Blanco Absolute Nature Reserve ranks 16th at under 5%. The best odds are in Tikal National Park (Guatemala, about 40%), Pico Bonito National Park (Honduras, about 30%) and Biotopo Cerro Cahuí (Guatemala, about 20%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Kentucky Warbler is recorded against all the birds logged in Cabo Blanco Absolute Nature Reserve (18 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.
