 The ability to return over unfamiliar territory to its ‘home’ – usually on a regular basis.

Navigation  Navigating their way home (includes migration) is innate, and requires: - A sense of direction (some sort of compass)

Methods of navigation   Landmarks – the animal recognises familiar landmarks and uses these as a guide. Common when close to home. Long distance can use coasts, and mountain ranges etc.

Bees and birds use this.  Stellar (stars) – Animals can orient themselves to the star patterns. Can use ‘pole’ stars when flying North/South. Birds use this.

Methods of navigation  Magnetic – Using the Earth’s magnetic fields. Birds, bees, whales and turtles use this.   Chemical (scent trails) – ants lay pheromone trails.
