Prevost's ground sparrow (Melozone biarcuata), also known as the white-faced ground sparrow, is an American sparrow. Its English name commemorates French naturalist Florent Prévost.

It is found typically at altitudes between 600 and 1600 m in the undergrowth and thickets of semi-open woodland, coffee plantations, hedgerows and large gardens.

Rare
Under 5% of wildlife watchers report a White-faced Ground-Sparrow sighting in Cusuco National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 201st most-seen of the 250 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
March and July
In those months about 10% of wildlife watchers report a White-faced Ground-Sparrow in Cusuco National Park on a given day, against under 5% in April–June and August–February, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most White-faced Ground-Sparrow sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 5
Of the 5 parks where we can rate White-faced Ground-Sparrow sightings, Cusuco National Park ranks 4th at under 5%. The best odds are in El Triunfo (Mexico, about 20%), Celaque National Park (Honduras, about 10%) and Cerro Azul Meámbar National Park (Honduras, under 5%).
Same family: Passerellidae

GBIF citizen-science records
It is estimated from how often the White-faced Ground-Sparrow is recorded against all the birds logged in Cusuco National Park (15 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.
