The influence of artificial light in urban spaces is a well-known phenomenon among birds, but is still not fully understood. Birds tend to migrate by night, and use the stars to navigate. By day, they use the position of the Sun to orient themselves. During nocturnal migration, they are often seen gathering around or crashing into lit-up windows and structures, or gathering around beams of projected life. The artificial glow of cities also appears to attract them for stopovers. One explanation is that they may generally fly towards light sources, but also, that the artificial light confuses, traps and disorients them.
I wonder if it’s a deer in the headlights effect or more like moths?
