The Australasian realm is a biogeographic realm that is coincident with, but not the same as, the geographical region of Australasia. The realm includes Australia, the island of New Guinea, and the eastern part of the Indonesian archipelago, including the island of Sulawesi, the Moluccas, and the islands of Lombok, Sumbawa, Sumba, Flores, and Timor, often known as the Lesser Sundas.
The Fea's petrel is a small seabird in the gadfly petrel genus, Pterodroma. It was previously considered to be a subspecies of the soft-plumaged petrel, but they are actually not closely related at all. However, P. feae is very closely related to Zino's petrel and Desertas petrel, two other species recently split from P. mollis. The gadfly petrels are named for their speedy weaving flight, as if evading horseflies. The flight action is also reflected in the genus name Pterodroma, from Ancient Greek pteron, "wing" and dromos, " runner". This species is named after the Italian zoologist Leonardo Fea (1852-1903).
Zino's petrel or the freira, is a species of small seabird in the gadfly petrel genus, endemic to the island of Madeira. This long-winged petrel has a grey back and wings, with a dark "W" marking across the wings, and a grey upper tail. The undersides of the wings are blackish apart from a triangle of white at the front edge near the body, and the belly is white with grey flanks. It is very similar in appearance to the slightly larger Fea's petrel, and separating these two Macaronesian species at sea is very challenging. It was formerly considered to be a subspecies of the soft-plumaged petrel, P. mollis, but they are not closely related, and Zino's was raised to the status of a species because of differences in morphology, calls, breeding behaviour and mitochondrial DNA. It is Europe's most endangered seabird, with breeding areas restricted to a few ledges high in the central mountains of Madeira.
The Pacific swallow is a small passerine bird in the swallow family. It breeds in tropical southern Asia and the islands of the south Pacific. It is resident apart from some local seasonal movements. This bird is associated with coasts, but is increasingly spreading to forested uplands. The hill swallow and the welcome swallow were formerly considered conspecific.
The Bismarck Sea lies in the southwestern Pacific Ocean within the nation of Papua New Guinea. It is located northeast of the island of New Guinea and south of the Bismarck Archipelago. It has coastlines in districts of the Islands Region, Momase Region, and Papua Region.
The Australian golden whistler or golden whistler, is a species of bird found in forest, woodland, mallee, mangrove and scrub in Australia. Most populations are resident, but some in south-eastern Australia migrate north during the winter. Its taxonomy is highly complex and remains a matter of dispute, with some authorities including as many as 59 subspecies of the golden whistler, while others treat several of these as separate species.
The Fiji petrel, also known as MacGillivray's petrel, is a small, dark gadfly petrel.
Hadoram Shirihai is an Israeli ornithologist and writer.
The brush cuckoo is a member of the cuckoo family.
Pseudobulweria is a genus of seabirds in the family Procellariidae. They have long been retained with the gadfly petrel genus Pterodroma despite morphological differences. Mitochondrial DNA cytochrome b sequence analysis has confirmed the split out of Pterodroma and places the genus closer to shearwaters. They thus represent either a plesiomorphic lineage still sharing some traits of the ancestral Procellariidae with the gadfly petrels, or convergent evolution of a shearwater to the ecological niche of gadfly petrels.
Blyth's hornbill, also known as the Papuan hornbill, is a large hornbill inhabiting the forest canopy in Wallacea and Melanesia. Its local name in Tok Pisin is kokomo.
The uniform swiftlet,, also known as the Vanikoro swiftlet or lowland swiftlet, is a gregarious, medium-sized swiftlet with a shallowly forked tail. The colouring is dark grey-brown, darker on the upperparts with somewhat paler underparts, especially on chin and throat. This species is widespread from the Philippines through Wallacea, New Guinea and Melanesia. It forages for flying insects primarily in lowland forests and open areas. It nests in caves where it uses its sense of echolocation, rare in birds, to navigate.
The Mascarene petrel is a medium-sized, dark petrel.
Beck's tree frog is a species of frog in the subfamily Pelodryadinae. It is endemic to Papua New Guinea. Its natural habitats are tropical moist montane forests, grasslands and streams. It was first described by the British biologist and herpetologist Arthur Loveridge in 1945 and is named in honour of the American ornithologist and explorer Rollo Beck who led the Whitney South Seas Expedition in the 1920s, collecting bird and other specimens from thousands of islands in the South Pacific.
The glossy swiftlet is a species of swift in the family Apodidae. It is found on the Indonesian island of Sulawesi and eastwards to New Guinea, the Bismarck Archipelago and the Solomon Islands.
The island imperial pigeon or floury imperial pigeon is a species of bird in the family Columbidae. It is found in the Bismarck Archipelago and the Solomon Islands archipelago, living in primary and secondary forests and mangroves. The International Union for Conservation of Nature (IUCN) has assessed it as a least-concern species.
Mountain pigeons are four species of birds in the genus Gymnophaps in the pigeon family Columbidae. They are found on islands in eastern Indonesia and Melanesia, where they inhabit hill and montane forest. They mostly have dull grey, white, or chestnut-brown plumage, with bright red skin around the eyes being their most distinctive feature. Males and females mostly look alike, but the Papuan mountain pigeon shows slight sexual dimorphism. Mountain pigeons are very social and are usually seen in flocks of 10–40 birds, although some species can form flocks of more than 100 individuals. They are generally quiet and do not make many vocalisations. However, they make a distinctive whooshing noise while leaving their high-altitude roosts to feed in the morning.
The pale mountain pigeon is a species of bird in the pigeon family Columbidae. It is endemic to the Solomon Islands archipelago, where it inhabits old-growth and secondary montane forest. It is a medium-size pigeon with an average length of 38 cm (15 in) and a weight of 310–385 g (10.9–13.6 oz). The head and neck are whitish-grey, the belly and lower breast are buffy-pink, and the vent and undertail coverts are pale grey. The upperparts are smoky-grey with darker fringes on the mantle and wing coverts. Both sexes look similar, but there can be large variation in individual appearance.
The pale-vented bush-hen is a medium sized waterbird, mainly blue-grey with a buff vent and undertail. It is found in Australia, the Moluccan Islands, New Guinea, the Bismarck Archipelago and the Solomon Islands. Its natural habitat is subtropical or tropical moist lowland forests.
