"After Mr Mason clipped his wings he grew very bad tempered"

Birds, their freedoms and restrictions, were a common metaphor through which writers explored the position of women in the nineteenth-century novel.

Coco is reminiscent of the parrot from Kate Chopin's  The Awakening (1899). In a novel about burgeoning female sexuality, the parrot meaningfully steals the opening scene:

A green and yellow parrot, which hung in a cage outside the door, kept repeating over and over:

'Allez vous en! Allez vous-en! Sapristi! That's all right!

As Lorri Dorrin says, bird imagery dominates this novel. So too in Jane Eyre. Jane is constantly compared to British birds, such as the linnet and the skylark, as David Anderson notes.
