White-eyes (Zosteropidae)

Thick-billed White-eye (Heleia crassirostris) - HBW 13, p. 483

French: Zostérops à bec fort German: Nacktaugen-Brillenvogel Spanish: Anteojitos Picogordo
Other common names: Lesser Sunda Lowland White-eye, Sunda/Stripe-headed/Flores White-eye

Taxonomy: Zosterops crassirostris E. J. O. Hartert, 1897, south Flores, Lesser Sundas.
Possibly forms a superspecies with H. muelleri, but the two seem to be very well differentiated in plumage and vocalizations. Birds from Sumbawa perhaps slightly larger and with perhaps more cream colour on crown, sometimes separated as junior (described from Batu Dulang), but differences from Flores birds considered insufficient to warrant naming of geographical races. Monotypic.

Distribution: Sumbawa and Flores (Lesser Sunda Is).
