Appearance:

Short foldable crest. Pale eye-ring and supercilium. Long primary projection (primaries extend well beyond tertials), white trailing edge to wing and white outer tail feathers. Tail much longer than in Wood Lark.

Sound:

Song a pleasing energetic stream of chirping, merry trills, interspersed with mimicry. Trills quite resonant with fairly full tone. Song usually given in flight high in the air. Less characteristic, shorter, weaker and more varied song when given from ground. Most typical flight call a short trilling "chirrup", with the end note noticeably lower pitched than the start. Also several other more cryptic calls.

Appearance:

Small owl with large, square head and spotted upperparts. Eyes bright yellow and facial disks white. "Astonished" expression. Size approximates that of Little Owl, but appears more bulky. Head much larger than in Pygmy Owl, and flight pattern includes interspersed glides without bounding. Seldom seen in the open.

Sound:

Song consists of fast series of fairly deep whistling notes "po-po-po-po-po-po-po-po", slightly ascending in pitch, and descending in the last few syllables. Phrase includes up to 25 units. Other calls include a drawn-out, squeaky "kweeat" and some peculiar, explosive sounds with an almost "electronic" quality.
