Two species of orioles, namely the Olive-backed Oriole (Oriolus sagittatus) and the Yellow Oriole (O. flavocinctus), occur across northern Australia. In New Guinea, both are confined to the Trans-Fly region immediately north of Cape York Peninsu[...]

The Pacific Ocean is the site of the most important diversification of insular reed warblers (Acrocephalus). In the Marquesas Islands (Eastern Polynesia), reed warblers belong to two distinct lineages that have reached the archipelago independen[...]

In New Guinea Palm Cockatoos, Pesquet’s Parrots and Eclectus Parrots are potentially threatened by deforestation and hunting. In a 28-month study, we found 51 Palm Cockatoo, 34 Pesquet’s Parrot and 71 Eclectus Parrot nests. Eclectus Parrots used[...]

A general pattern in biogeography is that species with high local abundances tend to have large geographic ranges, while species with low local abundances have small ranges. However, many tropical biotas do not show positive abundance–range–size[...]

Competition takes place not only between species but also within them. Intersexual competition for resources may increase sexual dimorphism in body size to minimise ecological niche overlap. Change in the level of sexual dimorphism in a species [...]

The White-shouldered Fairywren (Malurus alboscapulatus) is a tropical passerine bird distributed across much of New Guinea. White-shouldered Fairywrens are among few species of fairywren with exclusively tropical distributions and differ from be[...]

Three isolated areas of non-rainforested open woodland habitats, often collectively termed ‘savanna’, occur in eastern New Guinea and are here termed the Trans-Fly, Central Province and Oro Province savannas. Their avifauna is mostly shared with[...]

Half of Fiji’s 66 land bird species are endemic and 15 species are threatened with extinction following 70% deforestation. Under conditions of large-scale habitat loss, secondary vegetation can be important for woodland biodiversity conservation[...]

Parallel selection pressures in independent taxa can lead to the evolution of the same phenotype, but whether selection acts on the same molecular mechanisms may depend on the genetic biases of the convergent trait. For example, despite hundreds[...]

Species represent an important unit for the study of diversity, but may not always be delimited consistently across regions and clades. Many of these taxonomic inconsistencies are due to the variable views of taxonomists. In recent years, howeve[...]

The honeyeaters are the most species-rich clade of birds east of Wallace’s Line. They occupy a wide range of habitats, from desert to rainforest, and occur throughout Australia, New Guinea, and oceanic islands across Wallacea and the Pacific. Ho[...]

Complex spatial and temporal phylogenetic patterns have emerged among Pacific Island radiations and their Australian and New Guinean congeners. We explore the diversification of Australo-Pacific Petroica robins using the first phylogeny with com[...]
