Besides, is it safe to dissect owl pellets?

When the pellets are first regurgitated by the owl, they are not sterile and may contain harmful parasites or bacteria. To prevent these dangerous germs from passing to individuals who wish to dissect them, owl pellets are typically sterilized before packaged for selling.

What is owl poop?

Indigestible material left in the gizzard such as teeth, skulls, claws, and feathers are too dangerous to pass through the rest of the owl's digestive tract. To safely excrete this material, the owl's gizzard compacts it into a tight pellet that the owl regurgitates. The regurgitated pellets are known as owl pellets.

How do you prepare an owl pellet for a dissection?

The process is really quite simple: Wrap each pellet in a layer of aluminum foil and place it in an oven pre-heated to 325 degrees F. Forty minutes later, the entire pellet will have been heated to 325 degrees and that is hot enough to kill any bacteria such as E. coli or other bad stuff that might be present.

What types of bones did you recover from the pellet?
