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. This bird breeds at middle altitudes from southern Mexico to western Honduras. The Cabanis's ground sparrow was previously considered a subspecies. 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.
Prevost's ground sparrow is on average 15 cm long and weighs 28 g. The adult has a stubby dark-grey bill, unstreaked olive-brown upperparts, a rufous crown and mainly white underparts. Young birds are browner above, have yellower underparts, and a duller indistinct head pattern. It has a simple head pattern in which the rufous of the crown extends down the sides of the neck as a half collar behind the white face.
Usually found in pairs, the bird is a shy species best seen at or near dusk. They sometimes venture in the open in the early morning. The nest, built by the female, is a neat lined cup constructed... Wikipedia →

Rare
Under 5% of wildlife watchers report a White-faced Ground-Sparrow sighting in Cerro Azul Meámbar National Park on a given day, based on 30 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 214th most-seen of the 293 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.
February–March and May
In those months about 10% of wildlife watchers report a White-faced Ground-Sparrow in Cerro Azul Meámbar National Park on a given day, against under 5% in April and June–January, the lowest months. Those are among Cerro Azul Meámbar National Park's driest months, with about 120 mm of rain a month against 360 mm in September.
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.
3rd of 5
Of the 5 parks where we can rate White-faced Ground-Sparrow sightings, Cerro Azul Meámbar National Park ranks 3rd at under 5%. The best odds are in El Triunfo (Mexico, about 20%) and Celaque National Park (Honduras, about 10%).
GBIF citizen-science records
It is estimated from how often the White-faced Ground-Sparrow is recorded against all the birds logged in Cerro Azul Meámbar National Park (30 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.
