Nova Hollandia = region of Port Jackson, New South Wales, Australia.
Occasionally hybridizes with M. flavigula. Geographical variation on mainland apparently clinal, N populations tending to be slightly paler above (with little or no yellow-olive wash, more contrasting blackish and white tones) than those in S (more pronounced yellow-olive wash); also, wing becomes progressively longer from N to S (although one study found no significant regional differences in lengths of wing, tail and culmen). Recently proposed race lepidota (C New South Wales) merely reflects part of clinal variation; titaniota (E Cape York Peninsula) appears to be more distinctive and may merit recognition, but further study required. Two subspecies recognized.
