The Ingestion and Initial Processing An owl’s digestion begins with the consumption of its prey, which is typically swallowed whole or in large pieces. Regurgitation and the Final Stage Approximately 6 to 10 hours after eating, the owl regurgitates the pellet through its beak.
Unveiling the Power of the Owl Stomach: How They Break Down Prey
The Formation of the Pellet Not all components of the prey are digestible, particularly dense materials like fur, bones, teeth, and feathers. This process is distinct from vomiting, as it is a controlled expulsion of waste from the digestive tract rather than the stomach.
Inside the gizzard, tough keratin from feathers and the exoskeletons of insects are broken down by the contraction of muscular walls. Owls that consume small prey with hard outer shells, such as rodents or insects, rely on the gizzard to pulverize the material.
How Owls Use Their Gizzard to Digest Tough Prey Bones and Feathers
If the owl has ingested small stones or grit, these particles remain in the gizzard to assist in the grinding process. This initial chemical digestion is rapid, preparing the soft tissues for the next phase of processing.
