In the wild owls just put their pellets anywere why we knee deep in owl pellets?

Owls do not usually deposit their pellets in the same location. It is more common for them to disperse their pellets over a wide area. The concentration of pellets in certain areas may be due to several reasons, such as an abundance of prey in the area, owls roosting or nesting in the vicinity, or specific environmental conditions that influence pellet accumulation.
