I always see birds flying in the community, but I can't see a bird's nest in the tree?

There are many green belts in your community, and there are so many trees, big and small! Many birds eat a lot, so they keep flying around looking for food. These beneficial birds spend most of their time looking for food, so the green belt in the community is where they temporarily rest and look for food. Birds generally don't nest in the community. On the one hand, the flow of people in the community is relatively large, on the other hand, there are property management cleaners to clean up, and there will be no nests. Bird's Nest is generally quiet and peaceful, far away from city streets. If the park environment is perfect, you can also see the Bird's Nest.
