What you’ll learn

Maps written in the brainIntroduce migration as multi-cue navigation with compass and map components.Birds do not rely on one magic sense. Stars, sun, magnetism, and more form a toolkit. Young birds often start with compass vectors.
Learning the routeExplain vector navigation, routes, and fat as fuel strategy.First journeys may be inherited headings timed by biology. Coasts and weather shape real paths. Fat and stopovers are the energy system.
When the sky liesConnect human light and open scientific questions to navigation mechanisms.Artificial light and glass attack sensory systems evolution did not design for towers. Science is firm on multi-cue orientation and still refining magnetic details.

Questions this course answers

What best describes how many migratory birds find their way?

Birds combine celestial, magnetic, landmark, and other cues rather than relying on one infallible sensor.

Fueling enables flight; innate vectors launch novices; environment shapes the path; experience improves later maps.

Why can city lights disrupt night migration even if birds still have working wings?

Navigation depends on sensory cues; light pollution corrupts those cues and glass adds collision risk.
