Why is bird poop white? Why do birds pull white poop?

No matter what kind of bird they are, one of the biggest commonalities of their droppings is that they all have a white component, which is the final product of digestion of the protein they eat - uric acid, and uric acid is insoluble in water, so when it is excreted with water and other wastes, white crystals will be formed, which is also the reason why bird droppings are white.

Birds have to lose weight in order to fly, so they don't have a bladder to store urine, so bird feces and urine are patted out of the body together, and all bird feces have a white component, which is their urine The reason why the feces excreted by waterbirds that eat fish such as cormorants are basically white, and their food is related, because fish are rich in protein and have a high water content, and protein is absorbed or decomposed in digestion, so it is mainly white urine when excreted You can experiment with ducks. The feces excreted by ducks that eat fish and ducks that eat feed are completely different, the former is more white, and the latter is very little.

The first-level statement that the white droppings of birds are uric acid is correct, birds do not have urine, and the terminal metabolite of their protein is uric acid, which is insoluble in water, which is a characteristic of their weight loss and adaptation to flight life.

However, the protein terminal metabolite of many mammals is urea, which dissolves in water, rather than ammonia. Because ammonia is highly toxic, the liver must convert ammonia into urea. Urea.

It is less toxic and can stay in the body for a longer time without having to excrete it all the time.

Of course, aquatic animals excrete ammonia because their living environment is not short of water, and they can dissolve ammonia in water at any time and discharge it into the water environment, thus avoiding the poisoning of ammonia to the body.

The color of the stool is mainly affected by the bile pigment in the bile, and if there is no bile in the intestine, the stool is grayish-white, called white clay-like stool.

Sometimes it will be white, and it may be indigestion.

Why is the poop of birds white and the brown of humans? Today is a long insight.

The bird's digestive capacity is very strong, so that the weight can be lost in time to facilitate flight. Purely herbivorous birds, bird droppings generally do not have white things in them, because these white things are chitin that birds cannot digest. Chitin is a component of the exoskeleton of insects, so only birds that eat insects will have white things in their droppings.

It could be that there is something wrong with the bird's digestion.

The main reason why bird poop is so white is because it contains a lot of uric acid.

In order to fly, birds need to take in a lot of energy, they need to supplement a lot of protein, this protein can be worms, can be fish, can be other small animals, and after protein digestion, it produces uric acid, the end product that is insoluble in water.

Primates and mammals excrete waste in the form of urea, while birds and lizards, reptiles living in arid areas, excrete waste in the form of uric acid, because uric acid is insoluble in water and urea is soluble in water, so birds metabolize nitrogen through uric acid, which can also reduce water consumption in the body and reduce body weight. Uric acid forms white crystals.

But the whiter the bird droppings, the higher the uric acid content, and uric acid is not good for human health. After eating a lot of meat, the level of uric acid in the body will increase and gout will occur, so when you encounter additional "supplemented" uric acid, please rinse it off immediately.

There are generally three factors that determine the color of guano droppings.

1) It is determined by the color of the food and feed eaten.

Especially when digestion is not sufficient, the color of the bird droppings is closer to the color of the feed. For example, when indigo-chin birds are fed with crushed thrush feed after changing food, the color of bird droppings is often very close to the color of the feed, indicating that although insectivorous birds can be used to maintain life with other non-insect feeds after changing food, they cannot fully absorb the feed. It is still necessary for us to supplement it with bread worms and so on.

2) When eating.

Foods with a high iron content that are not fully absorbed.

, the color of the feces tends to be dark green.

The end product of the digested protein eaten is uric acid.

The droppings of birds in the wild, such as owls and blackbirds, which eat mainly meat and insects, are often almost completely white. On the other hand, the number of insects eaten by birds is also an important criterion for determining the dryness and wetness of bird droppings (in addition to disease factors) Bird droppings that usually eat more bread worms are generally thin and white, so as long as they do not stick to the anal hair, there is no need to worry.

Because birds want to lose weight in order to fly stool split, so there is no bladder to store urine, so bird feces and urine are patted out of the body together, and all bird feces have a white component, which is their urine The reason why the feces discharged by waterbirds such as cormorants and other fish-eating waterbirds are basically white, and their food is related, because fish are rich in protein and have a high water content, and the protein is absorbed or decomposed in the elimination of the source, so it is mainly white urine when excreted with ducks. The feces excreted by ducks that eat fish and ducks that eat feed are completely different, the former is more white, and the latter is very little.
