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 →

Possible
About 20% of wildlife watchers report a White-faced Ground-Sparrow sighting in El Triunfo on a given day, based on 34 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 98th most-seen of the 221 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
February
In that month about 50% of wildlife watchers report a White-faced Ground-Sparrow in El Triunfo on a given day, against about 10% in March–April and July–October, the lowest months. That is one of El Triunfo's driest months, with about 15 mm of rain against 420 mm in June. June has too few records to rate.
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.
Yes
Of the 5 parks where we can rate White-faced Ground-Sparrow sightings, El Triunfo has the highest daily chance: about 20%. Next come 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 El Triunfo (34 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.
