Other common names: Oceanic Flycatcher

Myiagra oceanica


, 1853,

Chuuk, Micronesia


Sometimes still considered conspecific with †M. freycineti, M. erythrops and M. pluto, although already treated as a species in late 1980s and 1990#R#R. Differs from M. erythrops and M. pluto in characters given under those species. Differs from the extinct †M. freycineti in its much larger size, most notably bill (effect size for males 8.68, score 3); greatly increased intensity and extent of rufous on underparts (3); darkish mouse-brown vs metallic green nape to rump in male (2); absence of pale rusty margins of wing-coverts and flight-feathers in female (2); and apparently somewhat different voice#R (ns). This arrangement is supported by molecular evidence#R#R. Monotypic.
