コガマグチヨタカ Batrachostomus affinis

Cryptic, uncommon nightbird of lowland and lower foothill forests (to 800 meters). Males show extensive barring on wings, whitish lower belly, and irregular white blotches on the breast. Females are warmer brown, almost rufous, with less wing barring and a wide “necklace” of white blotches on the breast. The only frogmouth in much of its western range. Vocalizations vary; male gives a series of rippling clear whistles and both sexes give harsh nasal croaks.
