I cannot believe that people still think that birds are harmful. They are really beneficial. What could be better proof if bird families living in a locals garden, their presence increases the harvest of crops. They are great predators, hunt and feed/ eat thousands of pests. They help create a good soil life, pollinate cultivated plants, stabilize ecosystems.
Unfortunately, with the narrowing of their natural habitats humans think of them as disturbing factors. They constantly complain about the noise they make, the harm they make in human possessions like house walls, cars, windows, the place they choose to nest. If their natural habitat was saved and protected, these so called problems would never exist.
I can vision a future where we try to create more natural living spaces for them, where our coexistence is more balanced( humans' needs are not always top priority), generations hand in hand are proud of them and appreciate all the ecosystem services they provide.
