• Behavior Stimulus• Circadian Rhythm Reflex• Ritual Pheromones• Hibernation Dominance• Hierarchy Migration• Fight or Flight Response Altruism• Imprinting Insight• Konrad Lorenz Habituation• Jane Goodall Ivan Pavlov• Operant Conditioning

BehaviorBehavior

• way an organism responds to it’s environment.

Skidboots – 8 minSkidboots – 8 min

StimulusStimulus

• Something in the environment to which an animal responds.

• Ex: sound, light, gravity, chemicals, heat and pressure.

Innate BehaviorInnate Behavior

• behavior present and complete without the need for experience. Rigid and unchangeable.

Circadian RhythmCircadian Rhythm

• 24 hour cycle of behavior.

MigrationMigration

• rhythm that occurs seasonally. Movement

• Change in day length is thought to stimulate the onset of migration in the same way that it controls the flowering of plants.

Behavior resulting from internal

and external cues

• Animals navigate in a variety of ways.

• Some use the positions of the sun and stars to navigate.

• They may use geographic clues, such as mountain ranges.

• Some bird species seem to be guided by Earth’s magnetic field.

Behavior resulting from internal and external cues

• Young animals may learn when and where to migrate by following their parents.

• How many animals cope with winter is another example of instinctive behavior.

• Many mammals, some birds, and a few other types of animals go into a deep sleep during parts of the cold winter months.

Behavior resulting from internal and external cues

HibernationHibernation

• state in which the body temperature drops substantially, and breathing rates decline to a few breaths per minute. Conserves energy.

Hibernation and Homing Hibernation and Homing 7 min7 min

EstivationEstivation

• state of reduced metabolism that occurs in animals living in conditions of intense heat.

ReflexReflex

• simple, innate, involuntary response by a part of the body to a particular stimulus. (Ex: fear)

Fight or Flight Fight or Flight responseresponse

• Ex: When you are frightened will you run or fight?

Territorial BehaviorTerritorial Behavior

• areas claimed by animals for hunting or raising young.

FAP - Fixed action patternFAP - Fixed action pattern

• complex innate behavior (instinct.)

• Ex: A goose instinctively retrieves an egg. Will retrieve any object of similar size and shape near nest.

Complex programmed behaviorComplex programmed behavior

• involves a series of complex steps.

• Ex: (bird building a nest)

Courtship behaviorsCourtship behaviors

• specific behavior or series of behaviors that take place to mating.

RitualRitual

• series of communication, behaviors performed the same way by all the males or females in a species.

CommunicationCommunication

• sounds, signals, songs of birds , etc.

Funniest Video Animals – Funniest Video Animals – 9min9min

PheromonesPheromones

• chemical that is released by many different types of animals as a form of communication.

• (Ex: in urine to mark territories of wolf. Ants to mark food trail. Bees use to signal a threat to hive.)

Social BehaviorSocial Behavior

• better chance of surviving as a group rather than alone.

Dominance / Aggressive behaviorDominance / Aggressive behavior

• behavior used to intimidate another animal of the same species.

• Ex: Male lion, deer using antlers

Hierarchy - pecking orderHierarchy - pecking order

• understood order within a group.• (Sometimes a young male may

challenge an older male, but runs the risk of injury, etc.)

Kin Selection - AltruismKin Selection - Altruism - -

• self sacrifice for the protection of relatives.

• Ex: honeybee stinging, dies in protecting the nest. A mother protecting her baby.

Learned BehaviorLearned Behavior

• any change in behavior that results from experience. ( social and parenting, songs of songbirds.)

HabituationHabituation

• When an animal learns to ignore given stimulus. Okay maybe not, but

funny!

ImprintingImprinting

• quick, early learning of a behavior that becomes a permanent response to a particular item.

• Critical period - time when imprinting occurs in an animals life, usually at an early age.

• (Young horses are imprinted to owner at birth)

• Soon after hatching, if baby ducklings see a cardboard box pulled by a string passing by, they'll follow the box as if it were their mother. Moreover, as the ducklings grow up, they'll continue following the box. They just do not catch on...

• Cranes, like other large water birds such as geese and ducks, lack the so-called homing instinct so prevalent in migratory songbirds. (They must learn to migrate from their parents.)

• To avoid identification with humans, crane-costumed handlers wield crane hand puppets to teach feeding.

• The goals of the process are: • Bonding with humans • Desensitization to certain stimuli • Sensitization to other stimuli • Submission to humans

Ivan PavlovIvan Pavlov

• 1900’s - did research with dogs. When a dog heard a bell they began to salivate.

• ( Classical conditioning based on a stimulus)

Classical ConditioningClassical Conditioning

• animals reflexes are trained to respond to a new stimulus.

Operant ConditioningOperant Conditioning

• when environment accidentally rewards certain behaviors that animals happen to perform accidentally.

• Trial and error learning behavior.

Charlie escapes again!Charlie escapes again!

Insight or ReasoningInsight or Reasoning

• to achieve solution, a thought process must occur. Use of the cerebrum. (Ex: in lab chimps would stack objects to reach bananas hanging from the ceiling.

Insight or ReasoningInsight or Reasoning

• An octopus would crawl out of it’s aquarium and raid the other tanks. They have even been known to unscrew jars.

Konrad LorenzKonrad Lorenz

• 1930’s did research and developed a theory on imprinting. Studied the behavior of young geese.

• (Imprinting)

Jane GoodallJane Goodall

• Zoologist - studied behaviors of chimpanzees and their social order.

• Found chimps used sticks as tools to get food.

According to the graph, is the song sung by this sparrow a learned or innate behavior? Explain.

Bird’s Songs

Wild sparrow

Sparrow raised inisolation

Question 2Question 2

The graph indicates that there is a difference in the song sung by the wild sparrow and the one raised in isolation, therefore the song must be a learned behavior.
