That's gross !
Does it stink ?
Don't touch it !
. . . at first !
Here's part of the story about owl pellets . . .
Owls, like a lot of other birds, eat their food whole. They can't chew their food because they have no teeth, so they use their beaks to rip their prey apart. Owls then swallow large chunks of that prey whole. They can digest the meat but not the bones or fur. So, the bones and fur are regurgitated (vomited, coughed . . . whatever word you want to use) in the form of a pellet.
Owls are carnivores which mean they eat birds, moles, mice, rabbits, skunks, frogs, insects to name a few of their meals. After they swallow the meal, it travels down the esophagus, through the proventriculus, and into the gizzard. There the meal is separated into two parts: what can be digested and what cannot be digested. The digestible part travels on through the owl's digestive tract. The bones and fur and anything that cannot be digested are formed into a pellet by the gizzard. Then the pellet travels back up into the proventriculus. The pellet is stored here for several hours and must be coughed back up before the owl can eat anything else.
Owl pellet can be ordered from several different places on the Internet.
Including Amazon. If you do order, try to find companies that include the Bone Sorting Chart.
If you look closely at the chart on the right, you can see just how many bones came out of ONE pellet !
