This species has a small population that is suspected to be declining owing to pressure from hunting for its plumes. However, it is tolerant of degraded habitats, with many rugged and inaccessible intermontane forests still supporting this species, and it is therefore classified as Vulnerable. Should this species be found to be declining at a more moderate rate, or indeed, not at all, it would qualify for downlisting to a lower category of threat.

30 cm. Dark bird-of-paradise with stout, ivory bill, broken white eye-ring and blue wings, back and tail. Male is otherwise black with fine, blue tail plumes and two long streamers. Female has chestnut underparts. Similar spp. Both the head pattern and the blue upperparts are unique. Other congeners are larger, slimmer and longer-tailed. Voice Displaying males give a slowly cadenced series of notes wahr..wahr.. and a metallic humming when inverted, also croaking and growling contact calls. Hints Can be seen in fruiting trees but to see males in their famous inverted display, seek local guides.
Survey western boundary of range. Survey historical sites in north and east of range. Estimate population densities and sizes at known sites. Investigate tolerance of secondary forest and degraded areas for both foraging and breeding, including the mapping and monitoring of male song-perches in populous mid-montane valleys (such as the Wahgi and Tari valleys). Research rates of forest loss in preferred altitudinal range. Monitor numbers at most accessible sites such as Ambua Lodge. Monitor trade prices and quantities. Investigate hunting levels and attitudes to control amongst hunters. Create large, locally-managed forest reserves with an enforced hunting ban. Run awareness and education programmes for landowners and highland inhabitants. Raise awareness of the conservation status of the species amongst tourists. Encourage traditional land custodians to conserve their existing plumes using effective storage methods. Enforce existing legislation. Utilise its well-known image as a flagship species for ecotourism and conservation ventures.
