#### Crop

A [crop](/wiki/Crop_%28anatomy%29 "Crop (anatomy)"), or croup, is a thin\-walled expanded portion of the [alimentary tract](/wiki/Alimentary_tract "Alimentary tract") used for the storage of food prior to digestion. In some birds it is an expanded, muscular pouch near the [gullet](/wiki/Gullet "Gullet") or throat. In adult doves and pigeons, the crop can produce [crop milk](/wiki/Crop_milk "Crop milk") to feed newly hatched birds.

Certain insects may have a crop or enlarged [esophagus](/wiki/Esophagus "Esophagus").
