Crop (anatomy)

Jump to: navigation, search

A crop is a thin-walled expanded portion of the alimentary tract used for the storage of food prior to digestion that is found in many animals, including gastropods, earthworms[1], leeches[2], insects, and birds.

Bees

Cropping is used by bees to temporarily store nectar of flowers. When bees "suck" nectar, it is stored in their crop.[3]

Birds

In a bird's digestive system, the crop is an expanded, muscular pouch near the gullet or throat. It is a part of the digestive tract, essentially an enlarged part of the esophagus. As with most other organisms that have a crop, the crop is used to temporarily store food. Not all birds have a crop. In adult doves and pigeons, the crop can produce crop milk to feed newly hatched birds.[4]
