The Xingu scythebill (Campylorhamphus multostriatus) is a species of bird in the subfamily Dendrocolaptinae of the ovenbird family Furnariidae.

[4] In July 2023 the International Ornithological Committee (IOC) adopted the split and in October 2023 the Clements taxonomy followed suit.

Their underparts are brown with wide buffy streaks that have indistinct darker borders on the breast that don't continue onto the belly.

It is somewhat similar to that of the curve-billed scythebill sensu stricto, which is described as "an accelerating series...of 7–9 somewhat melancholy whistles on even pitch or falling slightly...'weeee, weé, wee, we, we, wew' or 'kuweee, kuwee, kwee, wee-wee-we-we-we.

It has a somewhat limited range and its estimated population of between 13,000 and 41,000 mature individuals is believed to be decreasing "as a result of ongoing forest loss, degradation and fragmentation".

The habitat losses are attributed to "construction of hydro-electric power plants, mineral extraction and conversion to agriculture and pastureland".

[1] Though it is fairly common at a few sites with large bamboo thickets, and is present in several protected areas, it is "[h]ighly sensitive to habitat modification, requiring nearly continuous forest".
