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.

Appearance:

Olive green upperparts, yellowish chest with gradual transition to off-white belly. Very similar to Chiff-chaff, and most field characters are subtle and often hard to see. Distinguished by (usually) pale, yellow-brown legs, dark framing to ear-coverts, stronger supercilium. Long primary projection (often 3/4ths the length of tertials) with irregularly spaced tips (visible when wing folded). Wings slightly more pointed than in Chiff-chaff, and not so fan-shaped. Juveniles often with whole underparts yellow. Frequently flicks tail, but not sideways (unlike Chiff-chaff). Generally also more calm when moving among the foliage.

Sound:

By far most easily identified by it's call or song. Contact/alarm call a soft, plaintive ascending "hoo-eet". Similar to Chiff-chaff, but first part more drawn, giving it a disyllabic feel. Song: A 3-5 second, falling phrase of soft, rippling "svi-svi" sounds, starting high with some attack, and then falling in a mellow manner. The phrase lacks any conclusion, and diminishes both in strength and tempo.
