Crop (anatomy) Crop (anatomy) A crop (sometimes also called a croup or a craw, or ingluvies) is a thin-walled expanded portion of the alimentary tract used for the storage of food prior to digestion. This anatomical structure is found in a wide variety of animals. It has been found in birds, and in invertebrate animals including gastropods (snails and slugs), earthworms, leeches, and insects. Cropping is used by bees to temporarily store nectar of flowers. When bees "suck" nectar, it is stored in their crops. In a bird's digestive system, the crop is an expanded, muscular pouch near the gullet or throat.
Language of the birds Language of the birds In mythology, medieval literature and occultism, the language of the birds is postulated as a mystical, perfect divine language, green language, adamic language, Enochian, angelic language or a mythical or magical language used by birds to communicate with the initiated. In Indo-European religion, the behavior of birds has long been used for the purposes of divination by augurs. According to a suggestion by Walter Burkert, these customs may have their roots in the Paleolithic when, during the Ice Age, early humans looked for carrion by observing scavenging birds. There are also examples of contemporary bird-human communication
