Migration Advanced Biology – Spring 2013
WARM UP Why do animals migrate? Do humans migrate? List some differences and similarities between why each species below migrates. HumansBirds

Migration Techniques
PILOTING:
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 until it reaches its destination. 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.

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:
Types of Migration Seasonal Migration: Migration that corresponds with the changing of seasons. Most migrations are seasonal migrations.
Types of Migration Seasonal Migration: Migration that corresponds with the changing of seasons. Most migrations are seasonal migrations. Latitudinal Migration:
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.
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:
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:
Types of Migration Reproduction Migration: The migration of animals to bear young.
Types of Migration Reproduction Migration: The migration of animals to bear young. Removal Migration:
Types of Migration Reproduction Migration: The migration of animals to bear young. Removal Migration: Migration of animals that don’t return to the original area.
Types of Migration Reproduction Migration: The migration of animals to bear young. Removal Migration: Migration of animals that don’t return to the original area. Complete Migration:
Types of Migration Reproduction Migration: The migration of animals to bear young. 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.
Types of Migration Reproduction Migration: The migration of animals to bear young. 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. Partial Migration:
Types of Migration Reproduction Migration: The migration of animals to bear young. 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. Partial Migration: When some, but not all, of the species leave their breeding range during the non-breeding season.
