The daytime camouflage of the Tawny Frogmouth is extraordinary. Male and female pair permanently and during the day roost near one another on bare but sheltered branches, stumps, and even shaded ground. At the hint of threat or disturbance they freeze, compacting their plumage and closing eye slits and looking just like a broken branch. Only if pushed do they flash or react with a frightening snapping of their yellow, mouthed bills.
