Without walls and roofs, where would sparrows nest?

In this case, sparrows will nest in tree holes and bamboo branches and leaves.

1, tree hole: Sparrows tend to choose tree holes in big trees as nesting sites. These tree holes are generally located on the trunk or thick branches, and they are located at a high position, which can be far away from predators on the ground. The inner space of the tree hole is relatively spacious, which can provide enough activity space and habitat for sparrows.

2. On the branches and leaves of bamboo: In some areas, sparrows also choose to nest on the branches and leaves of bamboo forests. Because bamboo itself is dense, it forms a natural barrier between branches and leaves, which can provide some shelter and protection for sparrows, and the rich food sources in bamboo forests also provide survival guarantee for sparrows.
