Olive-faced Flatbill (Tolmomyias viridiceps)


French: Tyranneau à face olive German: Grünkopf-Breitschnabeltyrann Spanish: Picoplano cabeciverde

Rhynchocyclus viridiceps

P. L. Sclater and Salvin

, 1873,

Pebas, Peru


Usually considered conspecific with T. flaviventris, although sometimes split#R#R, as here: differs in its duller olive upperparts with little or no yellow or ochre tinge to head (1); more olive breast (1); very different song, having much shorter notes (at least 3) with higher frequency range, different note shape, and clear (vs loose, irregular) song pattern of 5–7 notes (2)#R. Proposed taxon borbae (Borba, on R Madeira, Brazil) is considered an intergrade between present species and T. flaviventris; more research needed in contact zone between the two species. Three subspecies recognized.
