We human are not the only species living in the city. Birds are also its residents. They need places to nest, but such needs have been long ignored. This redesigned wire pole has a hole on top for birds to nest. The hole has a little camera inside. Signals can be transmitted through blue teeth. You can search them and activate them through mobile phones or other equipments. The camera has a separate entrance for maintenance, so birds will not be bothered. A cash box below can accept donates to maintain the system work, its also a clue to remind you there are birds on top. We are good neighbors who care for each other.
