Akbaba is simply the Turkish word for Vulture, although it can also refer to a griffin. The name can also refer to the Egyptian mythology some pink birds are named for. According to wikipedia: The Akh (3ḫ meaning 'effective one'), was a concept that varied over the long history of ancient Egyptian belief. It is besides Ka and Ba one of the central elements, aspects of immortal personality, even after the death of the physical body. In this sense, it was a sort of ghost. In later belief, the Ka was considered to change into the Akh and Ba after death, rather than uniting with the Ba to become the Akh. At this stage, it was believed that the Akh spent some time dwelling in the underworld before returning and being reincarnated as a Ka, gaining a new Ba.
