Brown Jays, like this juvenile, make nesting a family affair. The entire flock takes care of a single nest, which holds four eggs laid by one female in the flock. Each bird brings food to the young. And when the young first leave the nest, the helpers teach them to find food and recognize danger, skills necessary for survival into adulthood. In turn, the helpers may inherit the nesting territory when they come of age.
