But why these birds eat clay? One of the most popular theories is that they simply lack sodium in the diet. Sodium is important for many functions of the body, such as generation of nerve impulses, maintaining electrolyte balance, cardiac activity and some metabolic functions.

Many herbivores whose diet is completely based on plants, need an additional salt, because plants do not contain a sufficient amount of salt. Therefore, animals often get sodium from solonts. Clay and soil are a good source of sodium, as well as many other nutrients such as potassium and magnesium.

Another theory is that birds eat clay to get rid of toxins. When they eat clay, clay particles are associated with toxins that occur in nature, such as chinin and tubyl acid, preventing their absorption of the gastrointestinal tract.

Nevertheless, studies show that sodium theory is more correct. Research Center Tambopata (TRC) in Peru studied clay and found that the soil that birds prefer to consume, do not have a higher level of cation exchange function, that is, the ability to absorb toxins.

The researchers observed how on one of the clay sites near the River Manu parrots actively eaten the lower layer of the soil, but the layer is avoided above. It was found that in a lower layer, sodium level is much higher than in the site that was above.
