A scythebill of large forest tracts between Brazil’s Xingu and Tocantins rivers. In live or freshly collected birds, the upper bill is distinctly blackish.
A comparison paper describes the upper maxilla as distinctly blackish in live or recently collected specimens.
An ICMBio assessment says it occurs only in large forest areas and appears to have disappeared from altered and fragmented sites where it had previously been recorded.
An extinction-risk assessment has not been added yet.
