Animal behavior: what an animal does when interacting with its environment
A lot of animal’s behaviors are genetically predetermined
- Ethology
Study of animal behavior
Didn’t exist
- People
Karl von Frisch
Applied scientific method to study bees
Figured out how bees tell other bees
Konrad Lorenz and Niko Tinbergen
Scandinavian
Their research helped to show that some behaviors have genetic bases
Nobel prize
- Evolution
Underlays all behavior
Behaviors enhance survival
- Genes and experience produce behaviors
- Lovebirds

Do things with precision, varies between species
Nest building
Types:
Fischer’s puts nesting material on the floor tears off a strip of paper carries material in beak up to nesting box
Peach-faced
carries material to nesting box tucked under tail
Hybrid
tear off longer piece of paper tried to tuck under tail, didn’t work instead, it brushed it upon the tail, but then carried it by mouth exhibited both behaviors showed genetic component of behavior important functions genetically predetermined experience influences hard-wired genetics plasticity Innate behavior
- Genetically predetermined behavior
- Genetic component to a lot of behaviors
- Important to evolution
- Lorenz and Tinbergen first to say these behaviors are vital
Fixed action patterns (FAP) unchanging behavioral sequence which must be done in its entirety innate response to certain stimulus the animal can’t change certain behaviors
Greylag goose
Domesticated goose in Scandinavia
Builds a shallow nest usually surrounded by water
When egg rolls away, mother has to get it head goes over egg then rolls it under until its under mother again will move in that direction even if egg isn’t there
