Owls feed early in the evening and regurgitate a single pellet approximately 20 hours after eating.
The protein enzymes and strong acids which occur in the digestive tract of raptors do not digest the entire meal.
The relatively weak stomach muscles of the bird don’t break the bones so most are found whole.
The owl pellets that you will be examining in this lab have been collected and STERILIZED from common barn owls.
Microscopes and hand lenses will help.
