Final answer:
The texts feature themes related to birds as symbols of freedom, change, and nature, and their influence on character evolution, such as Jane's transformation and Little Fay's growth from sorrow to joy.
Step-by-step explanation:
The excerpts provided from different texts allude to a common theme of birds and their metaphorical significance in storytelling. From the protective instincts of Jane Withersteen in the face of pain, suggested by the image of her with Fay, to Miss Lovebird's narrative during story time, and Sylvy's profound connection with birds and nature, there is a consistent portrayal of characters who are intimately linked with avian imagery.
In particular, the texts describe the birds as representations of freedom, change, and the innate wildness of nature, while also using them as a tool for character development and the unfolding of various narratives. The quotes highlight moments in which the characters interact with or are compared to birds, emphasizing their own personal growth, inner turmoil, or evolution, much like Jane's transformation into a 'lion-ess' or Little Fay's emergence from sorrow into joy.
