The xenopsaris is among the more enigmatic birds of the Neotropics. It is distributed widely south of the Amazon basin in brushy riparian growth, light woodlands and edges often near water but also is found in similar habitats across Venezuela and northern Brazil. Its status is very unclear over much of its range with evidence of nomadism and opportunistic breeding. Adding to the enigma, the xenopsaris is the only member of its genus, and its affinities within this group long have been obscure; recent research suggests it be closely related the becards. Superficially similar to many flycatchers and becards, the White-naped Xenopsaris has a gray back and wings with slightly scalloped white wing-bars and pale edging to the secondaries and a solid black cap with slight a crest contrasting with white throat, cheeks and underparts; it easily confused most easily with Cinereous Becard (Pachyramphus rufus).
