In Neil Gaiman’s book Norse Mythology, what is the name of the eagle perched atop Yggdrasil?

In Neil Gaiman’s Norse Mythology, the great eagle perched atop Yggdrasil is unnamed.

Gaiman retells the Norse myths in modern English while drawing primarily on the Poetic Edda and Prose Edda. In his account of Yggdrasil, the cosmic tree is inhabited by several creatures, including an eagle at its summit and a dragon or serpent at its roots. A squirrel named Ratatoskr carries insults between them.

A common mix-up is to assign the eagle a personal name from another figure. Vedrfolnir is the hawk associated with the eagle in some descriptions, while Hræsvelgr is a giant who takes eagle form in Norse cosmology. Neither is the eagle’s name in Gaiman’s retelling. The safest canonical answer for the book is therefore that the eagle is unnamed.

Gaiman’s Norse Mythology was published in 2017 and is a prose retelling rather than a new translation of one medieval manuscript.
