The black-polled yellowthroat was formally described in 1859 with its current binomial Geothlypis poliocephala. Some authors have placed the species in the monotypic genus Chamaethlypis but genetic data do not support this treatment.
The grey-crowned yellowthroat has these six subspecies: The species is sexually dimorphic. It has a long graduated tail and a stout bill with a visibly curved culmen. Adult males of the nominate subspecies G. p. poliocephala have a mostly olive-gray head with a gray crown, black lores, and white crescents above and below the eye.

Rare
Under 5% of wildlife watchers report a Gray-crowned Yellowthroat sighting in Santa Rosa National Park on a given day, based on 21 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 148th most-seen of the 233 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.
May and December
In those months about 10% of wildlife watchers report a Gray-crowned Yellowthroat in Santa Rosa National Park on a given day, against under 5% in January–April and June–November, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Gray-crowned Yellowthroat sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
10th of 31
Of the 31 parks where we can rate Gray-crowned Yellowthroat sightings, Santa Rosa National Park ranks 10th at under 5%. The best odds are in Rincón de la Vieja National Park (Costa Rica, about 20%), El Triunfo (Mexico, about 10%) and Tenorio Volcano National Park (Costa Rica, about 10%).
Same family: Parulidae
The closest relatives of the Gray-crowned Yellowthroat that you can see in Santa Rosa National Park (family Parulidae, New World Warblers) are Rufous-capped Warbler (about 50%), Yellow Warbler (about 40%) and Tennessee Warbler (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gray-crowned Yellowthroat is recorded against all the birds logged in Santa Rosa National Park (21 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.
