The crescent-chested warbler (Oreothlypis superciliosa) is a small New World warbler. It is common throughout its montane range, from northern Mexico to northern Nicaragua, and is an occasional vagrant to Arizona and Texas. It shows an affinity for oaks.
The crescent-chested warbler is superficially similar to both the northern parula and the tropical parula, with yellow underparts, a gray head, and a greenish back, but neither of these has a bold white eyebrow. Adult males have a discrete chestnut crescent on the breast, which is less prominent and sometimes lacking in females and young birds.
The species was formerly placed in the genus Parula, or Vermivora, but transferred to Oreothlypis following genetic analysis of the family Parulidae. Five subspecies are accepted: Oreothlypis superciliosa sodalis (Moore, RT, 1941) — Sierra Madre Occidental of western Mexico
Oreothlypis superciliosa mexicana (Bonaparte, CLJL, 1850) — Sierra Madre Oriental of eastern Mexico Oreothlypis superciliosa palliata (Van Rossem, AJ, 1939) — southwestern Mexico (southern Jalisco to western Michoacán and Guerrero)

Rare
Under 5% of wildlife watchers report a Crescent-chested Warbler sighting in Guatemala City on a given day, based on 220 verified sightings from GBIF citizen-science data. It is the 86th most-seen of the 220 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March to July
In those months about 10% of wildlife watchers report a Crescent-chested Warbler in Guatemala City on a given day, against under 5% in August to February, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Crescent-chested 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.
Yes
Of the 3 cities where we can rate Crescent-chested Warbler sightings, Guatemala City has the highest daily chance: under 5%. Next come Mexico City (México, under 5%) and Puebla (México, under 5%).

GBIF citizen-science records
It is estimated from how often the Crescent-chested Warbler is recorded against all the birds logged in Guatemala City (220 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.
