Glaucidium passerinum
Small size diagnostic. Small head in relation to body size, and distinct short white supercilia. Slightly protruding bill. Rather dark face, with only fine white markings and stern look. Juvenile lacks finely spotted crown. Bounding, woodpecker-like flight.
Calls in a clear voice, like a straight note blown on a recorder. Each note often followed by a rhythmic, trisyllabic accent a whole tone deeper than the first note.
