Range & population Cracticus louisiadensis is endemic to Tagula (= Sudest) Island (c.700 km²) in the Louisiade Archipelago of Papua New Guinea⁴. Ten were seen on the only recent visit to the island, during a 10-day trek from the north coast up to Mt Riu in 1992³. Over half of the forest on Tagula is already degraded and logging must remain a threat to all the lowland forest¹ although it may be similar to the allospecific Hooded Butcherbird C. cassicus is common and adaptable in forest edge habitat.

Ecology: Its population and ecology are virtually unknown but it is likely to be similar to the allospecific Hooded Butcherbird C. cassicus, which is a common and adaptable species, occurring in all forest edge habitats including gardens and savanna².

Threats Over half of the forest on Tagula is already degraded and logging must remain a threat to all the lowland forest¹.

Conservation measures underway None is known.

Conservation measures proposed Survey potentially suitable habitat on Tagula. Study its ecological requirements, tolerance of habitat degradation and threats.
