Description

The scaly-throated leaftosser is a medium-sized bird about in length with a long beak and short tail. It is similar to the tawny-throated leaftosser (''Sclerurus mexicanus'') in having deep brown upper parts, a tawny breast and dark brown underparts. It differs in not having a rufous rump, and in having a whitish throat, each feather on throat and breast having a black margin, which gives the bird the appearance of being scaled. The call is a harsh, shrill "Schreeek" and the song a descending series of clear whistling-notes.

Distribution

This species is native to Central America where it occurs on both the Pacific and Atlantic slopes. Its range extends from southern Mexico to northern Colombia and it inhabits lowland humid forests as well as forested foothills.

Ecology

Leaftossers are inconspicuous birds that move about the forest floor probing the leaf-litter with their beaks. They are difficult to observe, but may be recognised by the calls they emit, particularly at dawn and dusk. They usually forage alone, but sometimes do so in pairs, hopping rather than walking. As they search for small invertebrates among dead leaves, they flick the leaves noisily aside. They nest in holes in earth banks or among the exposed roots of fallen trees.

Status

The scaly-throated leaftosser has a very wide range but, although it is common in places, it is mostly an uncommon species.
