Avian juveniles that leave the care of an adult indeed show a tendency to seek larger prey items as they transition towards independence. This behavior is often driven by the need to establish their own territories and prove their hunting skills.

These larger prey items can also help them develop essential hunting techniques that they will use throughout their lives.

While other behaviors may vary among juvenile birds, such as their aggression towards parents or their flight patterns, the tendency to seek out larger prey directly correlates with their evolution toward independence and successful adult life.
