Bird's pouch is a term used to describe the anatomical structure of certain birds. It is also known as a CROP, and is located in the throat region of the bird. The CROP is a muscular pouch that stores food before it is digested. It is filled with air and can be seen as a bulge in the throat area. The CROP is connected to the esophagus and is filled with food that is swallowed by the bird. The CROP is also known as a CRAW, which is derived from the Old English word for throat.
