Document Summary
Eg. saying your cat is jealous (a human emotion) when it acts differently when you"re with other cats too. Animals and thus their behaviours are an integral part of human society. Any internally coordinated, externally visible pattern of activity that responds to changing external or internal conditions. An increase in testosterone levels in male giraffes during mating season - causes aggression. When it"s no longer mating season, the behaviour changes. Ethogram = inventory of an animal"s set of behaviours that it exhibits and a description of it. Ethogram ----------------> time budget (frequenc y *aka number* and time *aka duration*) Methods: recorded behaviour every 5 min for an entire day once a wk. Imp: these captive elephants had a high frequency of stereotyping: repetitive behaviour with no obvious purpose (eg. animal walking around in circles - not related to anything - no benefit)
