Calls - Otus sagittatus
Typical call Kaengkrajarn National Park, Thailand © Vetida Pongpanit

Introduction: Although a small owl, the White-fronted Scops Owl is relatively large for a scops owl, and has a relatively long tail and rounded wings. Perhaps the most striking feature of this bird is the prominent white forehead which extends into the large ear-tufts.

Description: The facial disc is pale rufous, with a broad ring of deep rufous-chestnut feathers around the eyes, and bordered by black-tipped feathers. The forehead and superciliary stripe extend to the ear-tufts, and are white with a pinkish tinge, obscurely vermiculated with fuscous. Eyes are deep brown to dark honey-brown with pink eyelids. The bill is bluish-white, and cere pale-bluish-green. The bristles around the base of the bill are whitish with black tips. A patch of close-set, pinkish-white, black-tipped feathers form a partial ruff extending from the chin to above the gape line.
Upperparts are rufous-chestnut, with the mantle and back having small, triangular, buffish-white spots with a black lower margin. The inner scapulars have similar but larger spots, and the outer scapulars are yellowish-white to rufous on the outer webs, with 3-4 moderately sized black spots on the shafts. The wings are rounded, with the ground colour similar to the back, with some darker and paler brown bars. The tail is chestnut-rufous with about ten transverse blackish bars that are more distinct on the outer feathers and towards the base.
Underparts are pale rufous, finely vermiculated with brown on the breast and throat, and each feather having a pale or whitish centre broken by a roundish black shaft-spot, the largest being on the centre of the belly.
