Why birds don't store undigested food?
Answers
Answer:
While the body can break down most foods, fiber remains largely undigested. However, eating fiber can be beneficial, because it adds bulk to the stool. Stool that's bulkier stimulates the walls of the intestines to move. This helps propel food material forward for digestion.
Explanation:
From the bill, food moves down a tube called the esophagus and into the crop, which stores excess food so the bird can digest it slowly. ... Waste: After digestion, any remaining material, both liquid and solid, passes through the cloaca to be expelled from the bird's body.
Flesh fly, from the family Sarcophagidae "blowing a bubble". One explanation for this behaviour is that it concentrates the fly's meal by the process of evaporation. The diet of the flesh fly is very high in water content. The fly regurgitates the liquid portion of the food, holds it while evaporation reduces the water content and the fly then swallows a much more concentrated meal without the water content. This continues until sufficient amount of liquid is left for the fly. - Australian Museum
Regurgitation is the expulsion of material from the pharynx, or esophagus, usually characterized by the presence of undigested food or blood.[1]
Regurgitation is used by a number of species to feed their young.[2] This is typically in circumstances where the young are at a fixed location and a parent must forage or hunt for food, especially under circumstances where the carriage of small prey would be subject to robbing by other predators or the whole prey is larger than can be carried to a den or nest. Some bird species also occasionally regurgitate pellets of indigestible matter such as bones and feathers.[3]
It is in most animals a normal and voluntary process unlike the complex vomiting reflex in response to toxins. Honey is produced by a process of regurgitation by honey bees, which is stored in the beehive as a primary food source.
