Imprinting is a behavior that occurs in some species of birds and mammals during a critical period early in life. During imprinting, the young animal forms a strong bond with the first moving object it sees. This object is usually the mother, but it can also be a sibling or even an inanimate object. Imprinting is important for the young animal's development, as it helps them to learn how to identify their own species and to form social bonds.
Specific bird songs are another example of innate behaviors. Each species of bird has its own unique song that is used to communicate with other members of the species. These songs are often learned from the parents, but some species of birds are born knowing how to sing their species-specific songs. Specific bird songs are important for communication, as they help birds to attract mates, defend their territory, and find food.
