Sparrows eat seeds but feed them with worms

Because young finches need a high amount of nutrients to grow fast and have a poor stomach function, unable to crush and digest nuts, mother finches are forced to use them to feed their babies.

Sparrow is one of the most numerous birds in the world. From high-rise buildings in the city to rural fields, we can see the presence of this bird everywhere.

It is known that it will be a bird species mainly eaten by seeds . Every day, they frequented fields and places where cereal crops were found for food. However, when it comes to breeding season, the bird chirps again to look for the worm.

Sparrows raise children.

According to many experts in bird studies, the reason for this is that young birds grow quickly, so their metabolism is very strong . Therefore, the young will need to be provided with nutritious food to meet the daily development needs.

Besides, because when young, the function of the digestive system has not developed completely, so the stomach of the young can not digest hard fruits and grains. Therefore, mother will be forced to find foods with high nutritional content, soft to feed chicks and foods that are full of these factors: insects, locusts, grasshoppers .

However, not the sparrow the parents will feed the chicks by insects until adulthood, but only use this food until the chicks can digest the grains. At that time, they will start to let me learn to eat seeds.

In the wild, it is not just a sparrow that has a strange way of raising children. Typically, in China there is a rare bird called the Sand-Horned Hornbill . This is a species of bird mainly eaten, but during the breeding season, parents often catch young birds of other birds or small animals to feed their children.
