There is evidence to suggest that some fish eggs might be able to survive the trip through a bird's digestive system. This explains how some species of fish end up where they may not belong.
a organ systems are shared by both fish and birds because they have the same respiratory system, nervous system and reproductive system.
Yes, birds produce gas as a byproduct of digestion just like other animals, so they do pass wind. However, since they have a different digestive system than mammals, their flatulence is less frequent and not as noticeable.
Yes. Birds are a living creature and since all living creatures have to get rid of waste matter, then yes. Besides, if you go down to your local shopping centre (if it has pigeons) then there will be bird excrement everywhere.
No, reptiles do not have gizzards. Gizzards are specialized organs found in birds that help them grind food. Reptiles have a different digestive system that does not include a gizzard.
gizzard, a muscular part of their digestive system where food is broken down with the help of stones or grit that the bird swallows. The gizzard helps birds digest harder food items like seeds and insects.
Cedar berries are eaten by birds, and pass through their digestive system. When the birds poop, the seeds grow where they land.

The male is nourished by the female but if the female does not return with food once the chick has hatched, he produces 'penguin milk' from his digestive system and regurgitates it for the chick. The young birds go to sea at about five months.
Raspberries are eaten by birds and other animals and the seeds pass through their digestive system and come out with manure to help them grow.
No, just a fast digestive system.
Yes, the human digestive system works through muscular contractions which force the food and liquid along. This is why we have no problems in space (apart from getting the food to stay on the plate). You can demonstrate this by hanging upside down and eating a sandwich just fine. Interestingly, the digestive system of many birds does depend on gravity; this was discovered during a Space Shuttle mission to see if birds could handle space.
Love grass disperses its seeds through animals that feed on the plant, such as birds or mammals. The seeds pass through the digestive system of the animal and are then deposited in a new location through their droppings.
it all depends on the animal, cow for example, have 4 organs that are like a stomache. birds, have a very different digestive system.
Usually by the fruit being eaten by birds or animals and the indigestible seeds passed through and dropped.
A gizzard is a muscular organ inside a bird that grinds up food.
