1. Three Reasons for Travel MigrationOrientationNavigation moving to and from a location knowing where you are based on land features/environme nt knowing/planning how to get to a place based on land/environment

2. MIGRATION DEFINITION: Animals move to leave and come back to an ecosystem Example: Birds fly to warmer climates and know to come back by a certain time frame.

3. MIGRATIONS “TAXIS” LIVING ORGANISMS USE SENSES/ADAPTATIONS TO MOVE LIVING THINGS MOVE BECAUSE OF ITS ENVIRONMENT Senses: *odor- skunks, flowers taste- monarch *taste- monarch butterfly *touch-humans, snakes *hear- birds, humans *see- humans, etc. *smell- dogs, cats, humans Environmental Influence: * currents- air or water * force of gravity *level of humidity *sun *weather/climate

4. MIGRATION MOVEMENT POSITIVE MOVE or “TAXIS”Definition: A stimulus that causes a living organism to move toward it Example:A lizard moves toward the sun for warmth

5. MIGRATION MOVEMENT NEGATIVE MOVE OR “TAXIS”Definition: A stimulus that causes a living organism to move away from it Example: a snail moves away from the sun to keep moist

6. ORIENTATION Definition: Knowing where you are based on location of abiotic and biotic factors Example: The sun rise or sun set allows birds to direct flight. Example: Dogs can orient based on smell of stimulus (person/other dogs)

7. ORIENTATION HOMING: returning to an area based on land marks/resources Example: Monarch Butterfly After mating, monarchs fly South to rest in a group After birth they fly North to eat, mate, and lay eggs on milkweed (midwest)

8. NAVIGATION Definition: Knowing your position and planning a route to follow Example: Birds use stars and the sun to map a route to and from places

9. NAVIGATION Geophysical: using land/physical features to plan a route Turtles: use ocean currents to travel
