The listener should learn three things: an example of how building lights at a local level can affect birds flight disruption, how/ why birds crash into buildings, and the beacon effect. We talked about the Nascar Hall of Fame museum as a great example of how large reflective windows and lights being emitted from it at night can be attractive to birds that are migrating. The will tend to crash into this building because it is brightly lit up, has large reflective buildings that blend in with the sky, and is at a level where birds tend to fly. A way to help prevent this is by dimming the lights and having a background behind windows that makes it more obvious something is here. Lastly, the beacon effect describes a phenomenon where bright beams of light traps birds in a ring where they fly for hours.
