2. How does an owl pellet form?

3. Catching the prey… Before an owl pellet can start to be formed, the owl must first catch its prey. Owls are carnivores and eat a wide variety of animals including: birds, moles, mice, shrews, rabbits, skunks, frogs, and much more.shrews

4. Swallowing the prey… Owls cannot chew their food because they don’t have any teeth. They must swallow their food whole or tear it up into large chunks first using their talons. Owl swallowing mouse

5. Digestion Process After an owl swallows its meal, it travels down the esophagus… Through the proventriculusproventriculus oGlandular stomach o where enzymes and acids begin digestion And into the gizzard oMuscular stomach

6. In the gizzard… The meal is separated into two parts. 1. The parts that ARE digestible o Soft parts (organs) o These parts continue on through the digestive tract to the small and large intestine and the waste is eventually excreted. 2. The parts that ARE NOT digestible. o bones, fur, teeth, and feathers o They are formed into a rounded pellet.

7. Holding the pellet After the gizzard has formed the pellet, it then pushes the pellet back up into the proventriculus (glandular stomach) The pellet is stored here for up to 10 hours. Before the owl can eat another meal it must first get rid of (regurgitate) the pellet! The pellet would be blocking the next meal from going to the gizzard if it didn’t get rid of it.

8. Regurgitation The final step for the owl is to regurgitate the pellet. While the owl is regurgitating the pellet, it looks like it is having difficulty breathing. It shows a pained expression, closes its eyes and ejects!It shows a pained expression, closes its eyes and ejects!
