The pellet cycle is regular, regurgitating the remains when the digestive system has finished extracting the nutrition from the food. This is often done at a favourite roost. When an Owl is about to produce a pellet, it will take on a pained expression – the eyes are closed, the facial disc narrow, and the bird will be reluctant to fly. At the moment of expulsion, the neck is stretched up and forward, the beak is opened, and the pellet simply drops out without any retching or spitting movements.

Owl pellets differ from other birds of prey in that they contain a greater proportion of food residue. This is because an Owl’s digestive juices are less acidic than in other birds of prey. Also, other raptors tend to pluck their prey to a much larger extent than Owls.
