Appearance:

Largely unmistakable. Chocolate brown body with small white dots. Wings and crown dark brown without spots. Tail dark with broad white edges/corners. Vent shiny white. Recognizable at long distance when in flight, by its peculiar flight pattern and profile. Fluttering, "inefficient" wing beats, short tail, long bill and often a throat bulging with seeds.

Sound:

Fairly silent. Warning call a characteristic dry and rasping "karrr karrr karr" in even pitch. Song a quiet improvisation of whistling and clappering sounds, interspersed with mimicry of other birds.

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.
