Bismarck Boobook Ninox variegata

A rather small owl with a grayish-brown head, brown upperparts spotted with white, and whitish underparts barred with rufous. Common in most forests up to at least 1000 meters of elevation. Differs from the similar New Britain Boobook in barred rather than spotted underparts, lack of contrastingly dark chest, and lack of slim white eyebrows. Ranges unlikely to regularly overlap. Voice is a gruff, frog-like “kra-kra-kra-kra.”
