Hide In Plain Sight

The phrase 'hide in plain sight' might well have been created after scientists discovered the potoo, a bird species found in Central and South America, if indeed you can actually spot one.  Their coloring helps them blend in with the scenery during the day when they are mainly inactive because they are nocturnal insect hunters.  They are masters at freezing in place if a potential threat is near and use minimal movement waiting for their prey to fly past them.  Their main diet is beetles, moths, grasshoppers and other flying insects.

Another reason for their camouflage is because they don't build a nest.  The female lays a single egg on top of a rotten stump or a depression in a branch of a tree.  Minimal movement during the day also helps protect the chick as it doesn't draw attention to the nest.

Their head is proportionately larger than the rest of the body and its broad bill helps catch the flying insects they eat.  Their large eyes help them to see their prey at night, and their eyelids have unusual slits in them to they can see predators during the day even with their eyes closed!
