Yeats continues to express his wishes and aspirations for his daughter in stanza six of "A Prayer for My Daughter." He wants her to be happy and pleased as she grows up. He wishes for her to become "a thriving secret tree" and her thoughts to be like a "linnet," a bird known for its purity and brightness. The word "linnet" is derived from the Old English liuen, which means "of the color of lime." This refers to the yellow feathers found on the bird's head and tail. The term "lintner" is used instead if you want to indicate that you have white feathers. However, since most linnets are not completely white, this would be an inaccurate description of their color. Linnets are small birds, usually between 15 and 20 centimeters long. They belong to the grouse family (Tetraonidae) and can be identified by their short tails, crests, and wings, which are colored in bright yellow or orange with black markings. The bill is short and curved, perfect for eating seeds. Although linnets are native to Europe, they have been introduced to other parts of the world where they have become established wild populations. Today, these birds are commonly kept as pets because of their attractive appearance and behavior patterns. They make good companions for people who like to walk in parks and gardens because they enjoy eating seeds just like we do!
