Conservation status of threatened and endemic birds of New Britain, Papua New 
Guinea - at

New Britain in the Bismarck Archipelago of Papua New Guinea supports 14 endemic 
bird species and together with New Ireland, forms an Endemic Bird Area that 
supports 38 restricted range species. Extensive conversion of lowland forest to 
oil palm plantations resulted in the loss of over 20% of forest under 100 m 
altitude between 1989 and 2000. However the rate of loss has subsequently 
slowed (2.2% loss across all altitudes between 2002 and 2014), and much forest 
remains at higher altitudes: 72% of New Britain remained forested (including 
secondary forest) in 2014. Despite the ongoing high threat and rich endemic 
bird fauna, the state of knowledge of the conservation status of birds in New 
Britain is very poor. We use an unprecedented dataset based on 415 hours of 
bird surveys conducted in oil palm plantations, as well as primary and 
secondary forests at all altitudes, to revise the IUCN status of New Britain’s 
birds. These data indicate that six species of elevated conservation concern 
are less dependent on old-growth forest than previously assessed. We recommend 
reduced population size estimates for one species, New Britain Kingfisher 
Todiramphus albonotatus. We recommend increased population size estimates for 
seven species: Pied Cuckoo-dove Reinwardtoena browni, Yellowish Imperial Pigeon 
Ducula subflavescens, Green-fronted Hanging Parrot Loriculus tener, Blue-eyed 
Cockatoo Cacatua opthalmica, Violaceous Coucal Centropus violaceous, New 
Britain Boobook Ninox odiosa and New Britain Thrush Zoothera talaseae. Despite 
our comprehensive surveys, Slaty-backed Goshawk Accipiter luteoschistaceus, New 
Britain Sparrowhawk Accipiter brachyurus, New Britain Bronzewing Henicophaps 
foersteri and Golden Masked-owl Tyto aurantia remain very rarely recorded and 
require further assessment. With ongoing habitat loss, particularly in lowland 
areas, New Britain’s birds urgently require more attention.
