Something amazing is happening here. In the video below, nesting swallows become trapped in a building when they add doors. The birds soon learn, though, that they can get the doors to automatically open by triggering the motion sensors. This is a story, obviously, of how smart birds are, but here’s what struck me: We often think about human technology as for humans. In this case, however, birds adapted the technology for their own very similar needs (to get in and out).
