This little-known species was for long classified as a data deficient species by the IUCN, due to the general lack of reliable data on its distribution and numbers.
The Bismarck Thicketbird is classified as Vulnerable (VU), considered to be facing a high risk of extinction in the wild.
The Bismarck Thicketbird (Megalurulus grosvenori) is a bird species. Previously placed in the "Old World Warbler" family Sylviidae, it does not seem to be a close relative of the typical warblers; probably it belongs in the newly-recognized grass-warbler family Megaluridae. It is found only in the rarely visited highlands of the island of New Britain in Papua New Guinea. More

the Bismarck honeyeater, and the Bismarck thicketbird, found nowhere else in the world. It is likely that these mysterious forests contain birds not yet discovered or described. Cause for Concern The ecoregion is largely intact, probably because of its steep slopes and small trees. Logging operations are a threat to the region. Logging also increases the spread of non-native species in an area. For more information on this ecoregion, go to the World Wildlife Fund Scientific Report. More
