Campylorhamphus pucherani The greater scythebill (Drymotoxeres pucheranii) is a Near Threatened species of suboscine passerine bird in the subfamily Dendrocolaptinae of the ovenbird family Furnariidae.

Their crown and nape have thin buff streaks that sometimes continue onto the upper back.

Their underparts are rufous-brown to chestnut with grayish streaks on the throat, breast, and sometimes the upper belly.

Their iris is dark brown, their bill dull pinkish horn to creamy gray with a blackish base to the culmen, and their legs and feet brownish gray to dark brown.

It hitches up trunks and branches, gleaning prey from the surface and probing into crevices and moss.

"This scarce and poorly known species has a moderately small, fragmented distribution, and is likely to be declining in most areas owing to ongoing habitat loss.

"[1] The species is "[b]elieved to be highly sensitive to human disturbance in a region where habitat loss is extensive and continuing, if not accelerating.
