Editing Digestion (section)

====Crop====
A [[Crop (anatomy)|crop]], or croup, is a thin-walled expanded portion of the [[alimentary tract]] used for the storage of food prior to digestion. In some birds it is an expanded, muscular pouch near the [[gullet]] or throat. In adult doves and pigeons, the crop can produce [[crop milk]] to feed newly hatched birds.<ref name=Gordon>{{cite web | title=The Alimentary Canal in Birds | url=http://www.earthlife.net/birds/digestion.html | author=Gordon John Larkman Ramel | date=2008-09-29 | access-date=2008-12-16}}</ref>

Certain insects may have a crop or enlarged [[esophagus]].
