Come fall and spring, migratory songbirds and shorebirds are programmed to do two things: fly and eat. These species are known informally to scientists as “super collider” species because of their high collision rates. Birds navigate during migration in part by sensing the Earth’s magnetic field, and some scientists have speculated that artificial light may disrupt a light-sensitive internal magnetic compass. Migratory birds are known to rely on Earth's magnetic field to help them navigate the globe. When flying at night, many migratory bird species produce short vocalizations known as flight calls.
