A lot of birds eat seeds, but switch over to a diet consisting of mostly bugs during the nesting season. In nature there is a balance.
In 1958 Mao Zedong, leader of the Chinese Revolution, declared sparrows an enemy of the state because they ate grains in the field. Farmers were given incentives to kill all they could find. The balance in nature was interrupted.

The war against the sparrows was terminated in 1959. Scientists autopsied the digestive systems of the sparrows and found that three-quarters of the contents were harmful insects and only one-quarter was grain. This showed that sparrows were basically a beneficial bird.
