19. Common Potoo
Common Potoo bird
Endemic to Central and South America, common potoos (Nyctibius griseus) are solitary birds that typically live on trees but are hard to spot because they look like them.
These strange birds are nocturnal and feed on insects like grasshoppers, termites, and moths.
What makes them ugly birds is their camouflage-like appearance which makes it easy for them to “disappear” on the tree trunk; their bodies seem to be broken branches!
