Ecology

This species lives in tropical to subtropical, moist montane forest. The altitudes reach 1,200 to 1,800 m. New Britain Sparrowhawks nest like other birds, where they raise their young. Very little is known about this species because it is so rare and the areas in which it lives have not been thoroughly studied http://www.iucnredlist.org/search/details.php/91/all.

Conservation

it is estimated that the population is only between 1,000 and 2,499 individuals http://www.birdlife.org/datazone/search/species_search.html?action=SpcHTMDetails.asp&sid=3451&m=0. The main threat to the continued existence of this species is habitat destruction which has led to the birds' decline in lowland forests. The clearing of forest on the small islands leaves the species with less habitat, and a far less safe environment – leading to their vulnerability. No conservation measures are known to have been taken; however it has been proposed that surveys be made to assess population size and observe nests, as well as to map the remaining forest. There are also plans to lobby for large community-based conservation areas http://www.iucnredlist.org/search/details.php/91/all.
