Which navigational failure occurs in seabirds exposed to bright artificial upward-pointing lights onshore?

💡 Explanation

Directed artificial light at night (DALAN) creates light pollution, misleading migratory birds; *phototaxis* attracts them disastrously because these lights are seen as an unobstructed path, therefore birds become fatally disoriented and circle indefinitely, rather than maintaining their proper flight vectors.
