Male has gray throat and upper breast becoming white in the belly with some gray bars. Female has white underparts with dark gray bars except from the lower belly to the tail. Both sexes have a dark patch from the bill to slightly behind the eye, giving a masked impression. Juvenile is brownish, heavily scaled with whitish-buff, and mottled on the underparts. Immature has broader white edges to wing feathers. Vocal. Call is a two-noted, rather nasal “gii-yaak,” uttered in flight as well as from a perch. Inhabits lightly wooded country, avoiding wet forests.
