• Three techniques animals use to migrate.
Migration Techniques• PILOTING:• When an animals moves from one familiar landmark to another
until it reaches its destination.
Migration Techniques• PILOTING:• When an animals moves from one familiar landmark to another

• ORIENTATION:
Migration Techniques• PILOTING:• When an animals moves from one familiar landmark to another
until it reaches its destination.
• ORIENTATION:• Animals can detect compass directions and travels in a particular
straight line path for a certain distance or until it reaches its destination.

• NAVIGATION:• When one determines one’s present location relative to other
locations, in addition to orientation.
Types of Migration• Seasonal Migration:• Migration that corresponds with the changing of seasons. • Most migrations are seasonal migrations.

• Latitudinal Migration:• Movement of animals from North to South.
• Altitudinal Migration:• The movement of animals up and down land features, like
mountains.
Types of Migration• Reproduction Migration:• The migration of animals to bear young.
• Removal Migration:

• Removal Migration:• Migration of animals that don’t return to the original area.

• Complete Migration:• When almost all members of the species leave their breeding
range during the non-breeding season.
