what is eagle crop
The esophagus is a tube-like structure which passes food in portions, to an organ known as the crop. The crop is an organ unique to birds. A crop's main function is to store food. It is like an extra fuel tank for the bird. The crop is located at the base of the neck and can be easily seen after a bird has just eaten. If the crop is large in size the bird is probably full. If the crop is deflated and has a flat appearance the bird has not eaten yet. The crop continuously supplies small amounts of the food to the stomach. The food passes from the crop to the stomach, the most active part of the digestive system of a bird. There are two parts to the stomach of a bird.
