Fiona mentally repeated the incantation of, "Avis," in her mind ensuring she got the right pronunciation. After feeling confident that she had done so, it was time to practice the correct wand movement. Fiona traced her wand in the air in the avian formation that Professor Carton had demonstrated.

As she practiced, she began to think about the bird that she wanted to conjure. Soon, her mind decided upon a raven. In her opinion, this was a very beautiful and highly intelligent bird. Fiona would normally close her eyes to visualize but recent events taught her to be on alert so she kept her eyes open as she pictured the sleek black feathers that could sometimes have an iridescent purple hue to them, the strong beak used to devour its prey, the strong yet streamlined shape of their body.

Once that vivid image was in her mind, Fiona went up to where the bird cages were and retrieved one for herself. She hoped that there was an expansion charm of some sort because fitting more than one raven in a cage could prove a difficult feat.
