The rufous-capped warbler (Basileuterus rufifrons) is a species of bird in the family Parulidae, the New World warblers. It is found in Belize, Guatemala, and Mexico. It also occurs as a casual visitor to the U. S. states of Arizona and Texas.
The rufous-capped warbler has a complicated taxonomic history. It was formally described in 1838 with the binomial Setophaga rufifrons. For a time in the nineteenth century it was placed in a new genus Idiotes. In 1902 Robert Ridgway assigned it to its present genus Basileuterus. By the end of the twentieth century it had been assigned eight subspecies, several of which had been treated by various authors as full species.
The further taxonomy of the rufous-capped warbler remains unsettled. In 2021 the American Ornithological Society, the IOC, and the Clements taxonomy split three of the subspecies as the chestnut-capped warbler (M. delatrii). They retained these five subspecies as the rufous-capped warbler:

Rare
Under 5% of wildlife watchers report a Rufous-capped Warbler sighting in Cusuco National Park on a given day, based on 24 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 164th most-seen of the 250 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.
March and September
In those months about 10% of wildlife watchers report a Rufous-capped Warbler in Cusuco National Park on a given day, against under 5% in April–August and October–February, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Rufous-capped 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.
17th of 35
Of the 35 parks where we can rate Rufous-capped Warbler sightings, Cusuco National Park ranks 17th at under 5%. The best odds are in Santa Rosa National Park (Costa Rica, about 50%), Rincón de la Vieja National Park (Costa Rica, about 50%) and Cumbres de Monterrey National Park (Mexico, about 50%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Rufous-capped Warbler is recorded against all the birds logged in Cusuco National Park (24 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.
