Thornbills (Acanthizidae)

Chatham Gerygone (Gerygone albofrontata) - HBW 12, p. 596

French: Gérygone des Chatham German: Langschnabelgerygone Spanish: Gerigón de las Chatham
Other common names: Chatham Island Gerygone/Warbler, Chatham (Island) Flyeater

Taxonomy: Gerygone? albofrontata G. R. Gray, 1844, Chatham Islands.
Relationships uncertain. May constitute a well-differentiated member of the superspecies formed by G. mouki and G. igata, presumably following rapid evolution after colonization by a small founder population; alternatively, may not be a derivative of G. igata but, instead, the result of an earlier invasion by a gerygone that has since become extinct on the New Zealand mainland. Monotypic.

Distribution: Chatham Is, E of New Zealand.
