Tyrant-flycatchers (Tyrannidae)
Northern Bentbill (Oncostoma cinereigulare) - HBW 9, p. 316
French: Bec-en-arc cendré
German: Graukehl-Krummschnabeltyrann
Spanish: Mosquerito Piquicurvo Norteño
Other common names: Bent-billed Flycatcher, Grey-throated Bentbill
Taxonomy: Todirostrum cinereigulare P. L. Sclater, 1857, Córdoba, Veracruz, Mexico.
Has been suggested by some authors that genus be joined with closely affiliated Hemitriccus or Lophotriccus; bill morphology and peculiar voice, however, viewed by others as sufficiently distinct to support retention of separate genus. Forms a superspecies with O. olivaceum, and sometimes considered conspecific. Distribution somewhat uncertain; one specimen from NW Antioquia, in Colombia, identified as belonging to present species on basis of yellow underparts, possibly representing disjunct population separated from nearest one (W Panama) by 400-600 km; slight variation ..

Distribution somewhat uncertain; one specimen from NW Antioquia, in Colombia, identified as belonging to present species on basis of yellow underparts, possibly representing disjunct population separated from nearest one (W Panama) by 400-600 km; slight variation in belly colour of present species, however, leads to questions about true identity of this specimen. Monotypic.
Distribution: S Mexico S to W Panama (possibly in Bocas del Toro and N Veraguas).
