A well known example of unintentional opportunity providing is the transmission of feeding behavior in black rats (Rattus rattus). One pilot study determined that black rats living in the forests of Palestine preferentially fed on pine cones instead of other fresh fruits and vegetation nearby.
Instinctive drift is the tendency of an animal to revert to instinctive behaviors that can interfere with learned responses. The concept originated with Keller and Marian Breland when they taught a raccoon to put coins into a box. The raccoon drifted to its instinctive behavior of rubbing the coins with its paws, as it would do when foraging ...
The synthesis of their studies consisted of two phases, in which they (1) created a comprehensive list of cultural variant behavior specific to certain populations of chimpanzees and (2) rated the behavior as either customary – occurring in all individuals within that population; habitual – not present in all individuals, but repeated in ...
But this pre-programmed response can be altered by experience. For example, if the posture fails to deter certain threats, the cat may no longer use it in response to them. While some species-typical behavior is learned from the parents, it is also sometimes the product of a fixed action pattern, also known as an innate releasing mechanism (IRM ...
For example, male zebra finches appear to prefer mates with the appearance of the female bird that rears them. [7] Sexual attraction to humans can develop in non-human mammals or birds as a result of sexual imprinting when reared from young by humans. One example is London Zoo female giant panda Chi Chi.
Habituation processes are adaptive, allowing animals to adjust their innate behaviors to changes in their natural world. A natural animal instinct, for example, is to protect themselves and their territory from any danger and potential predators. An animal needs to respond quickly to the sudden appearance of a predator.
The ability for socially-learned behaviors to stabilize across generations is also mitigated by the complexity of the behavior. Different individuals of a species, like crows, vary in their ability to use a complex tool. Finally, a behavior's stability in animal culture depends on the context in which they learn a behavior.
