Slaty Flowerpiercer (Diglossa plumbea)


French: Percefleur ardoisé German: Einfarb-Hakenschnabel Spanish: Pinchaflor plomizo

Diglossa plumbea


, 1861,

Costa Rica


Closely related to and formerly considered conspecific with D. baritula and D. sittoides, genetic data suggesting that the three form a monophyletic group. Proposed race veraguensis (described from Cordillera de Veraguas, in SW Panama) is now considered inseparable from populations in rest of species’ range. Monotypic.


Highlands of Costa Rica (from C Guanacaste) S to W Panama (E to Veraguas).
