What do baby blue jay know after they hatch?

After hatching, baby blue jays, or nestlings, have limited knowledge and abilities. They are born blind and featherless, relying entirely on their parents for warmth, food, and protection. Instinctively, they know to open their mouths for feeding and will respond to parental calls. As they grow, they begin to develop awareness of their surroundings and the behaviors necessary for survival.
