Doesn't the ba bird as a pictograph of the soul (think spiritual manifestation) strike you as peculiar? Do you not wonder how the Ancient Egyptians' assignment of the representation of the soul known as "Ba" to a migratory bird not lead you to question how we got the modern word bird from? Have you ever sat outside at sunset and listened to birds soaring across the sky screaming out "ka ka ka"? I often wondered why these Egyptians did not equate the bird with their concept of ka? Until it struck me they had it right all along. These birds were frantically searching for their ka.
