The Potoo, the perfect camouflage bird: 

The Potoo is a bird that lives in Venezuela woods, and it is known for its amazing camouflage ability.  Its feather camouflage- a mottle of gray and brown- allows it perfectly to resemble tree bark. Thus, as it sits on a tree branch, it cannot be spotted as a bird and no cutting line will split it from the tree bark.  

This is incredible. Let us see on the screen how difficult it is to differentiate between the feathers of the potoo bird and the tree bark.

The tree is on the left and the bird is on the right. It looks exactly as a broken-off stub of the branch. The only thing that distinguishes it from the tree bark is its eyes and beak. However, this bird can skillfully make use of its cryptic coloring when it is in danger, so it starts to camouflage by closing its eyes and beak to look exactly like a branch.

 Its design is perfect, as it has narrow openings along the bottom of its eye lids letting it see around it even while closing its eyes.

The minute danger disappears, it relaxes, and gets back to its normal behaviour.    
Notice the great similarity between the potoo and the tree bark. The designer of this program has drown a white line to help us distinguish between the feather of the bird and the tree branch on which it is sitting. 

The creation of this bird manifests "The Work of Allah, Who perfected all things..". Allah, Exalted and Sublime be He, has created the heavens and the earth and in everything He has created, there is a Divine Sign that indicates His Oneness.
