Birds don't have teeth. They are the only class of vertebrates without teeth. Instead, they have a gizzard that grinds food, located between their crop and intestine. Some birds swallow clams and mussels whole and their gizzard grinds the shells into digestible material.

 

"I've never been to a birding festival before, but I think the bar has now been set pretty high for any future bird outings that I might go to. They really take care of you at the New River Festival. For one thing, having your meals provided for you is a huge convenience that I didn't appreciate until I came home and realized that I had to go back to fixing my own meals." - Heather
