Female Wagtail has a yellow plumage on her front, which wraps up into a swirly pattern on her face. Her back is comprised of light brown feathers, as are the feathers closest to her head. Her feathers then turn white and are tipped with black. Her tail feathers are also black, as are her talons and beak. Her eyes are brown.
Although not much has been revealed, Female Wagtail is a rather doubting little bird, finding it hard to believe that Beshte could break through a rock, despite his status as strongest in the Pride Lands.
Female Wagtail hitches a ride on Beshte's back along with Chura, Laini and Young Aardvark while he makes the Hippo Lanes. When they reach a large rock, she watches Beshte break it apart. She comments to Chura that she didn't believe that Beshte was going to make it, which angers Chura, who reminds her that he's the strongest in the Pride Lands. Despite this, she still admits that she had her doubts, prompting Chura to tell Beshte to ignore her.
When Beshte later explains how the Hippo Lanes work, she joins in singing to Makin' Hippo Lanes. When Young Aardvark leaves, she flies away from Beshte herself without uttering another word.
