EtymologyIts English name commemorates French naturalist Florent Prévost.[2] Distribution and habitatThis 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.[3] DescriptionPrevost'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. BehaviourUsually 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.[3] BreedingThe nest, built by the female, is a neat lined cup constructed less than 2 m up in a bush or large tussock. The female lays a clutch of two or three ruddy-blotched white eggs, which she incubates for 12–14 days. The male helps in feeding the chicks. This species is sometimes parasitised by the bronzed cowbird. FeedingThe bird feeds on the ground on seeds, fallen berries, insects and spiders. VoiceCalls include a thin tsit or a clearer psee. The male’s song, given from a hidden perch in the wet season, is a whistled pst’t’t’t peer peer peer whee whee whee.
