The great xenops (Megaxenops parnaguae) is a furnariid bird, which is endemic to the Caatinga region of north-eastern Brazil. It is monotypic within the genus Megaxenops. Its name refers to the superficial similarities to the "true" xenopses of the genus Xenops. Its bill is similarly up-curved, but with a total length of c. 16 cm (6 in), it is noticeably larger and overall bright cinnamon-rufous with a white throat. It is generally inconspicuous, typically foraging amongst foliage rather than on trunks.
