The juvenile Rufous Potoo (Nyctibius bracteatus) is a master of camouflage. The bird has taken the strategy of camouflage to the next level.
It is a nocturnal bird that stays on a perch during the day.
It has lumps that mimic the perch it sits on during the day.
To go unnoticed, the bird imitates a leaf swaying in the wind and varies with the speed of the wind.
