Migratory Songbirds Have a Specialized Night-Vision Brain Area

Research shows special molecules help the birds navigate at night

Neurobiologists have discovered a specialized night-vision brain area in night-migratory songbirds. They believe the area might enable the birds to navigate by the stars, and to visually detect the earth's magnetic field through photoreceptor molecules, whose light-sensitivity is modulated by the field.
