Birds tend to target others they perceive as weak, often singling out those that are sick or injured. This behavior may stem from a survival instinct, as weaker individuals can be seen as easier targets or a potential threat to the health of the flock. The aggression towards vulnerable birds could also be a way of ensuring that the stronger, healthier members of the group thrive. This natural dynamic can be tough to witness, but it's a part of how birds maintain balance within their social structures.
