What are the benefits of birds to humans?

Birds are not only beautiful creatures in nature, but they also have many benefits for humans. Here are some of the benefits of birds to humans:

1. Control pests: Many birds such as swallows, robins and bee-eaters eat a large number of insects, including various pests such as mosquitoes, flies, ants, etc., which can help us control the number of these pests.

2. Spread plant seeds: Some birds, such as finches and parrots, like to eat fruits and seeds and spread these seeds to other places through their excrement, promoting the dispersion and prosperity of plants.

3. Improves human mental health: Watching birds can improve human mental health. Research shows that watching birds can reduce negative emotions such as stress, anxiety and depression, and enhance happiness and quality of life.

4. Beautify the environment: Birds live in the natural environment and can beautify the environment. Having birds in a city park, garden, or home backyard can bring more natural beauty and life to the surrounding environment.

It is important to note that some birds may pose a threat to humans under certain circumstances. For example, pigeons, seagulls, etc. will build nests on urban buildings and breed bacteria and pathogens on the streets, so their populations need to be properly controlled.
