Final answer:
The question does not specify how birds take flying lessons in 'Birds of a different feather.' In nature, birds might learn individually or in groups, mirroring behavior during duties like egg incubation. Migratory birds, for instance, fly collectively in formations.
Step-by-step explanation:
When considering the flight lessons of birds mentioned in Birds of a different feather, the text does not provide a specific answer to whether all the birds take turns or all go at once during their flying lessons. However, in nature, flying birds, especially during their early stages of flight, may learn to fly by observing and mimicking their parents and through practice, which could be done both individually or in groups. For example, parental birds often take turns while incubating their eggs, suggesting they also might take turns during other tasks like teaching their offspring to fly. Nonetheless, in real life, birds can also flock and fly together, such as in migratory birds like Canada geese, who fly in formation as governed by the laws of physics. Additionally, birds exhibit a wide range of behaviors, and these could influence how they undertake flying lessons, whether individually or collectively.
