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 Lago de Yojoa on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 232nd most-seen of the 263 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a White-faced Ground-Sparrow in Lago de Yojoa on a given day, so our monthly data shows no clear season.
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.
5th of 5
Of the 5 parks where we can rate White-faced Ground-Sparrow sightings, Lago de Yojoa ranks 5th 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%).
GBIF citizen-science records
It is estimated from how often the White-faced Ground-Sparrow is recorded against all the birds logged in Lago de Yojoa (10 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.
