The Luzon boobook is one of the smallest of the owls in the
Philippine hawk-owl complex. It has white eyebrow-like streaks above the eyes and the
beak and a white moustache forming an x-shape on the head. It does not have tufts of feathers on its head resembling ears. The upper parts of all subspecies are brown, and the wings are mottled with oval-shaped white spots. The tail is dark brown with narrow white stripes. The sides of the head are brown, the chin is a whitish colour, while the rest of the underparts are pale white with wide brown streaks which are more prominent on the breast. The underside of the tail is white. The chequered subspecies have these reticulated patterns on the underparts, on the head, the upper parts of the back and the wings. The feet are partially covered with feathers and are pale yellow. The beak is olive. ==Taxonomy==
