Behavioral Biology

Behavioural biology examines the behaviour of humans and animals and investigates which behaviour is innate and which skills are learned in the course of life. An overview of our research.

In house mice, the pay-off of mating with multiple males depends especially on the quality of food available to mothers more

Orangutans engage in feeding activities, perched on tree branches, consuming leaves and fruits in a dense forest environment.

Researchers reveal just how much wild orangutans depend on social learning to build diets spanning hundreds of different foods more

Two macaws sit on wooden perches in a room, separated by a window. In front of them are two experimenters; the one at the back gives a hand signal indicating a turn.

First evidence of imitation from a third-party perspective outside of humans  more

Researchers find that behavioral flexibility is related to exploration, and that great-tailed grackles disperse farther at their range edge more

Scientific highlights 2022

December 14, 2022

Many publications by Max Planck scientists in 2022 were of great social relevance or met with a great media response. We have selected 12 articles to present you with an overview of some noteworthy research of the year more

"Fish are not stupid, they're just different!"

Fish are his passion. Alex Jordan wants to know why they do what they do. An interview with the behavioural biologist more

"In my opinion, 'social distancing’ is the wrong term"

The primatologist Roman Wittig explains in this interview, why he prefers to speak in terms of "spatial” rather than “social” distancing, and how virtual (online) meetings can replace real meetings to a certain extent. more

Even chimpanzees and six-year-old infants want to punish antisocial behaviour more

Migration pays off for songbirds

Blackbirds that spend the winter in the south are more likely to survive the cold season than their conspecifics in central Europe more

Chimpanzees fill another’s knowledge gap

Researchers show that vocalizing in chimpanzees is influenced by social cognitive processes more

Chimpanzees and sooty mangabeys interfere with other group members’ relationships

Bystanders monitor and intervene into grooming interactions of their group members if these threaten their own status or social relationships more

Food odour enhances male flies’ attractiveness

When female flies smell their favorite food, they become more receptive to courting males more

Grey parrots help others to obtain food

Scientists from the Max Planck Institute for Ornithology based at the research station outpost for parrot comparative cognition in the Loro Parque in Tenerife, Spain, have shown that parrots exhibit a high level of social intelligence and cooperativeness. They readily help others, even when there is no immediate opportunity for reciprocation. Moreover, they reciprocate received favours and do not appear jealous, if conspecifics obtain a better reward than themselves. more

Dogs' clever minds

Dogs and humans have been living together for 15,000 years – a long time to get used to each other.  Behavioural biologists at the Max Planck Institute for Evolutionary Anthropology in Leipzig are investigating how well the animals have adapted to humans. They discovered that dogs are frequently better at understanding human gestures than other animal species. For example, dogs understand referential gestures, such as pointing, and realise they can get away with doing something forbidden when their owners just happen to be looking elsewhere. more
