- Ethologists study animal behaviour
- Tinbergen
- Studied innate behaviour in gulls
- Tinbergen wanted to find out whether the red spot on the beak of adult gulls made the chicks peck the beak and get food
- He showed newly hatched chicks cardboard gull heads with different colour spots
- He counted the number of times that the chicks pecked the different spots in a given time
- The chicks pecked at the beaks with red spots most often
- Conclusion: chicks are born with an instinct to peck at the red spot that helps them find food
- The chicks pecked at the beaks with red spots most often
- He counted the number of times that the chicks pecked the different spots in a given time

- Lorenz
- Studied imprinting in geese
- Took two groups of goose eggs
- Group 2: Geese were hatched in an incubator with no mother
- Goose chicks had formed an attachment to the first moving object they saw - Lorenz
- Group 2: Geese were hatched in an incubator with no mother
- Took two groups of goose eggs
- Studied imprinting in geese
- Fossey and Goodall
- Fossey: Studied mountain gorillas in Africa
- Spent time getting close to the apes in their natural habitats
- Watched animals to see how they behaved and recorded what they saw
- Gorilla and chimpanzees are social animals - they live in groups
- Examples of social behaviour:
- Apes worked together to search for food sources - more food
- Protected each other from attacks
- Males in the group had social rank (dominant at the top) - prevented fights
- Apes groomed each other to keep clean
- Examples of social behaviour:

- Goodall: Studied chimpanzees in Tanzania
- Fossey: Studied mountain gorillas in Africa
