Morepork though he followed Mees in treating them as a single species. Janette Norman and colleagues tested the cytochrome "b" DNA of three subspecies (as well as the powerful and rufous owls) to ascertain whether the closest relative was used in breeding with the last surviving female of the Norfolk boobook. They discovered that although the Norfolk boobook was similar in plumage to the Tasmanian boobook, it was genetically much closer to the New Zealand subspecies. In fact, the two were so close genetically that they considered whether the Norfolk boobook should be recognised as a separate taxon at all, although
Australasian figbird for example parrots and other species of orioles. The song consists of a series of simple whistles. As suggested by their name, Australasian figbirds are largely frugivorous, but also take small insects, nectar and small seeds. While largely a resident species (although the southern population may be migratory), it is nomadic in response to the availability of food. Unlike most orioles, Australasian figbirds are gregarious, often forming flocks of 20 to 40 birds during the non-breeding season, and even breeding in small, loose colonies. The flimsy saucer-shaped nest is made from plant-material, and usually placed relatively high in a tree.
