Sparrows often act as foster moms to ensure the survival of their species, particularly when resources are plentiful. By adopting and raising chicks that are not their own, they increase the chances of those young birds thriving and contributing to the population. This behavior can also occur when the biological parents are unable to care for their offspring due to various reasons, allowing the foster parents to enhance reproductive success in their environment. Such altruistic behavior demonstrates the adaptability and social nature of sparrows.
