All owls produce pellets because that is from eating rodents and getting rid of fur and bones.
There are things that the owl doesn't digeste, these things form an owl pellet. Every owl has one. The type of things in the owl pellets are bones from smaller animals that the eat, and hair from the animal that the owl eats. This is my detail fact about What is in an owl pellet.
They might have been small enough to swallow. If the skull is missing, an adult owl might have torn off the head and brought it to her baby. Then, the pellet could have belonged to the offspring.
Things that are found in owl pellets ecosystems are mites, carpet beetles, fungi and clothes moths. Owls eat all kinds of bugs they also eat mice. Schools use these pellets to teach environmental science.
An owl pellet is a conglomeration of undigested material that the owl has regurgitated. This is not fecal material. It is regurgitated out of the beak. It is a consequence of a canivorous bird eating its prey whole. Hawks and falcons do the same thing. These pellets look gray or brown and are an inch or two long (3-5 cm). They often contain a lot of hair and so a person may easily think it is the decayed remains of a dead mouse. It can include a mouse meal, but it is what remains after after the bird has finished digestion. There is clearly an evolutionary advantage to a process that extracts the high value nutrients which may represent a small fraction of the material in the meal. It saves the energy of processing indigestible material and saves the weight, perhaps the most important aspect for a bird. A bird's pellet can be analysed to determine its diet and may the pellet may contain insects parts, indigestible plant matter, bones, fur, feathers, bills, claws, and teeth.
A tricky question, if the prey was large enough to sustain the owl, just one, however if the prey was only small and the owl needed many, then may prey would be the answer.
depending on the food it eats where the pellet was found u can look in an owl pellet guide
to find out what the owl has eaten
The A hole
The owl pellet remans in the owls rectum until the owl decides it would be a good time to puke it out.
The outside of an owl pellet is covered in a thin slime, to assist the owl with ejecting the pellet, the undigested fur or feather tends to be the next layer, with the undigested bones on the inside.
The owl pellet shows what the owl has eaten.

One important thing you can learn from studying an owl pellet is learning what animal the bones in the owl pellet belong to.
