What happens to the nutrients in the crop of a bird?

In birds, the crop serves as a temporary storage pouch for food before it moves to the stomach. Nutrients in the food are not absorbed in the crop; instead, they are broken down further in the proventriculus and gizzard, where digestion occurs. Enzymes and acids help to break down the food, allowing nutrients to be absorbed in the intestine later. Ultimately, the nutrients are utilized for energy, growth, and other bodily functions.
