Its underparts are whitish, with an unmarked pale throat, a dark barred upper breast and barring on the remainder of the underparts. Its face is dark brown, its eyes are brown or yellow, and its bill and legs are yellow.[3] It is short-tailed and has heavy tarsi (the part of the leg above what is commonly referred to as the foot).[4] Endemic to the Bismarck archipelago, it occurs on the islands of New Britain, New Ireland and New Hanover,[5] where it lives in forested lowlands, hills and mountains, up to an altitude of {{convert|1000|m|ft|abbr=on}}.[2]It was first described as Noctua variegata by French naturalists Jean René Constant Quoy and Joseph Paul Gaimard in 1830.[5] Although its population size has not been quantified, it is widespread and fairly common in forest and forest edges within its range, and its numbers are thought to be stable.[6] Deforestation is thought to be a likely threat to the species.[7] References1. ^{{IUCN|id=22689475 |title=Ninox variegata |assessor=BirdLife International |assessor-link=BirdLife International |version=2012.1 |year=2012 |accessdate=16 July 2012}} {{Taxonbar|from=Q1265886}}{{DEFAULTSORT:boobook, New Ireland}}2. ^1 2 {{cite book |title=Owls (Strigiformes): Annotated and Illustrated Checklist |first=Friedhelm |last=Weick |publisher=Springer |location= |year=2002 |page=228 |isbn=3-540-35234-1}} 3. ^{{cite book |title=Owls: A Guide to the Owls of the World |first1=Claus |last1=König |first2=Friedhelm |last2=Weick |first3=J.
