Migrating is a behavior that requires Chewy to be introduced into a flock. Sandhill cranes are migratory birds that typically travel in flocks during migration. Imprinting is a behavior that occurs when a young animal forms an attachment to the first moving object it encounters after hatching. In the case of Chewy, she has imprinted on a young woman, which may cause her to view humans as her flock instead of other sandhill cranes. To ensure Chewy's successful migration, she would need to be introduced to a flock of sandhill cranes to learn their migratory routes and behaviors.
Recognizing people and eating are not behaviors that necessarily require Chewy to be introduced into a flock. Sandhill cranes are omnivores and can feed on a variety of foods, including seeds, insects, and small animals. While Chewy may have a preference for human-provided food, she can still learn to forage and feed on her own or with a flock. Additionally, recognizing people is not a behavior that would prevent Chewy from joining a flock, but it may require training or conditioning to ensure that she recognizes other sandhill cranes as part of her social group.
Flying is also not a behavior that necessarily requires Chewy to be introduced into a flock, but it is a behavior that can be learned through social interaction with other sandhill cranes. Flying is a natural behavior for sandhill cranes and is essential for their survival during migration. Chewy may be able to fly on her own, but she may benefit from the guidance and support of a flock during migration.
