Gerygone modesta

, 1860,

Norfolk Island, in Tasman Sea

.

Sister to G. igata, based on DNA data#R. In past, these two (together with extinct †G. insularis of Lord Howe I) were considered conspecific, a treatment recently resurrected by some authors#R. However, here maintained separate, as present species differs from igata in its longer bill (effect size based on published data#R, although n=6 for G. modesta, 2.42; score 2); subterminally darker tail with reduced white spotting (2); and, on basis of descriptions and only two recordings of modesta, a different, more “nervous” song, with more frequent drops and rises in frequency (2) and a loud abrupt vs gently fading finish (2). Monotypic.

Distribution:

Norfolk I (including vegetated N islets), E of Australia.
