The Rainbow Owl is a rare species of owl found in hardwood forests in the western United States and parts of China. Unlike most owls, which are nocturnal, the Rainbow Owl is active during the twilight hours at dawn and dusk, or on bright moonlit nights. The Rainbow Owl can be distinguished from other owls by its peculiar multicolored feathers but also by its unusually melodic call. Recent research also suggests that they are responsive to music and attracted to human singing.
