Lovebirds are well known for mirroring the behaviour of their cage-mates, a form of social facilitation. Social facilitation in animals is when the performance of a behaviour by an animal increases the probability of other animals also engaging in that behaviour or increasing the intensity of the behaviour.
Evidence for animal culture is often based on studies of feeding behaviors, [8] vocalizations, [4] predator avoidance, [9] mate selection, [10] and migratory routes. [11] An important area of study for animal culture is vocal learning, the ability to make new sounds through imitation. [4] Most species cannot learn to imitate sounds.
Synchronous behavior is also threatened when animals in a mixed-sex herd have differing nutritional or physical necessities. This causes group instability which often splits the herd up into two separate groups; generally all male and all female, to recreate the mimetic behavior in a smaller, same-sex group that has more similar needs to the individual.

The concept of "reciprocal altruism", as introduced by Trivers, suggests that altruism, defined as an act of helping another individual while incurring some cost for this act, could have evolved since it might be beneficial to incur this cost if there is a chance of being in a reverse situation where the individual who was helped before may perform an altruistic act towards the individual who ...
For example, the learner may observe an unwanted behavior and the subsequent consequences, and thus learn to refrain from that behavior. For example, Riopelle (1960) found that monkeys did better with observational learning if they saw the "tutor" monkey make a mistake before making the right choice. [17]
Collective animal behaviour is a form of social behavior involving the coordinated behavior of large groups of similar animals as well as emergent properties of these groups. This can include the costs and benefits of group membership, the transfer of information, decision-making process, locomotion and synchronization of the group.
Rats, for example, really like it when we tickle them. In 2023, researchers found that when tickled, rats squeak joyfully in a high-pitched noise, similar to a giggling sound.
Examples of studies that have explored these capacities and tendencies in primates are listed in a table within the ‘Research on Imitation and Emulation in Primates’ section below. Beyond the studies listed, in a naturalistic environment, imitative learning is seen in many animal species.
