The great potoo (Nyctibius grandis) is a bird, both the largest potoo species and the largest member of the order Caprimulgiformes (nightjars and allies). It occurs in tropical America.
Potholes are cylindrical holes drilled into the rocky bed of a river by burbulent high-velocity water loaded with pebbles. The pebbles become trapped in slight hollows and vertical eddies in the water are strong eneough to allow the sediment to grind a hole into the rock be abrasion (corrasion).otholes can vary in width from a few centimetres to several metres. They are generally found in the upper or early-middle course of a river. This is where the valley lies well above base level, giving more potential for downcutting, and where the river bed is more likely to be rocky in nature.
