Animal Behavior Mrs. Rightler
Methods of Study Comparative psychology Ethology Behavioral ecology Sociobiology
Instinct Basic set of behaviors present at birth May need a trigger Behavior improves or changes with experience
Maturation Behavior seen after a period of development has occurred Improvement or change not based on experience but on time Ex. Tadpole swimming techniques
Imprinting Konrad Lorenz Critical time period ONLY Young animal develops attachment to another animal or object Rapid learning
Habituation Animal trained to ignore stimuli Dog examples
Classical Conditioning Pavlov’s dog Animal learns to respond to particular stimuli Basic obedience training
Instrumental Conditioning Trial-and-error learning Skinner Box Behavior can be “shaped”
Latent Learning Exploratory learning No obvious reward Helps animal learn about its surroundings
Insight Learning Animal uses experiences and thinking to solve problems. Tool use Primates
Behavior is Controlled by: Nervous system Endocrine system – Organizational effects – Activational effects
Animal Communication Transfer of information from one animal to the other (both must be mutually adapted) Visual Auditory Tacticle Chemical
Habitat Selection Two factors influence habitat choice – Physiological – Psychological
Foraging Behavior Process of locating food resources Cost vs. benefit analysis – Handling time – Nutritional value – Status value – Concentration/density
Specialists vs. Generalist
Social Behavior Members of the same species Usually live full-time in groups Can refer to predator-prey interactions
Group Living Animal society – stable group of individuals of the same species that have cooperative relationships outside of mating and raising young. Invertebrates and vertebrates
Advantages to Group Life Protection from predators Increase feeding efficiency Protection from elements Easy access to potential mates
Disadvantages of Group Life Competition for resources Diseases Parasites
Aggression Agonistic behavior Attacks Threat displays Maintains territory Maintains dominance hierarchy
Altruism Individual sacrifices reproductive potential for the benefit of others in the group – Honeybees – Turkeys – Naked mole rats Kin selection

Social Behavior Members of the same species Usually live full-time in groups Can refer to predator-prey interactions.
Animal Interactions Responses to the biotic environment.
Chapter 51 Reading Quiz 1.What an animal does and how it does it is known as ____. 2.From what 2 main sources is behavior derived? 3.The full set of food-obtaining.
Adaptive Behavioral Responses
Animal Behavior. Behavior BEHAVIOR -The way an organism responds to changes in its internal and external environment. IS ESSENTIAL FOR A SPECIES SURVIVAL.
Chapter 34 Animal Behavior
Behavioral responses to stimuli may be adaptive.
Animal Behavior Chapter 51. Behavior Animal responds to stimuli Food odor Singing.
Behavioral Ecology Chapter 37. Nature vs. Nurture Behavior To what degree do our genes (nature) and environmental influences (nurture) affect behavior?
Ethology = the study of animal behavior Behavior = a response to a stimulus.
Animal Behavior Male Jumping Spider (Habronattus icenoglei)
ANIMAL BEHAVIOR. Behavior Behavior can occur in response to an internal or external stimulus. Study of behavior and its relationship to evolutionary.
Animal Behavior Chapter 34 /. What is a behavior? Any response to a stimulus (an external signal) Examples of stimuli Sounds Smells Sights (light vs dark)
Animal Behavior Ecology Unit.
Behavioral Biology Chapter 55
Animal Behavior CVHS Chapter 51. Behavior What an animal does and how it does it Proximate causation – “how” –environmental stimuli, genetics, anatomy.
