Noronha Vireo Vireo gracilirostris

  • © Stephen John Jones

Considered Near Threatened, the Noronha Vireo is one of just three native landbirds on the Brazilian territory of Fernando de Noronha, and has in the past sometimes been considered conspecific with the Red-eyed Vireo (Vireo olivaceus). These two species clearly belong to the same superspecies, although the Noronha Vireo differs from the geographically closest subspecies of the Red-eyed Vireo in its overall much duller coloration, longer tail, longer and finer bill, and shorter primaries, as well as having brownish irides. The Noronha Vireo inhabits both forest and scrub, including gardens, and seems to have an unusually protracted breeding season. It remains reasonably common in the present day, but was presumably more widespread historically, prior to human colonization of the island.
