Indigestible parts would be the hair and bones that the owl does not digest- they cough up what are known as 'pellets'- these pellets are comprised of the undigested bones and hair.
After digesting all the edible parts, they cough the indigestible parts up into a compounded ball known as an owl pellet.
Owl pellets are pieces of fur, bones, teeth, and any other indigestible parts that the owl is unable to digest, which are then regurgitated. Droppings are what is digested while pellets are what cannot be digested, so they are not the same thing.
Around two per day, so 700+ every year. The owl pellets contain indigestible hair and bone, so it depends on how much and what type of prey a particular owl eats.
Yes. Owls produce castings which are balls of indigestible materials that have passed through the owls intestinal tract.
It gets digested. The parts that can't be broken down are regurgitated as an owl pellet.
They occasionally regurgitate owl pellets which are balls of indigestible material like animal hair and bones. They digest most of their food and excrete owl pellets which are undigested food that has passed through their digestive tract.
The incubation period for Barn Swallows is 12 to 17 days. Generally the clutch size is about 3 to 7 eggs.

The bones and indigestable objects all get clumped together in a pellet. The owl basically regurgitates the pellet.

No. A pellet is the mass of undigested parts of a bird's food that some bird species (such as owls) regurgitate. The contents of a bird's pellet depend on its diet, but can include the exoskeletons of insects, indigestible plant matter, bones, fur, feathers, bills, claws, and teeth.
Nothing. Owl pellets are made of the indigestible part of the animals an owl eats. (bones and fur) since there is nothing edible inside of them, no other animals use them as a food source. Source: I'm an apprentice falconer
