Very little is known about King Horus-Bird. The few
archaeological evidences point to the existence of one or more ephemeral rulers following
Qa'a's death and before
Hotepsekhemwy of which Horus-Bird may have been one. Egyptologists such as
Jaroslav Černý and Kaplony think that Horus-Bird could be identical to the likewise sparsely attested King
Horus-Ba. Indeed, this ruler wrote his name with the leg sign or the leg and ram signs, which read "Ba". Černý and Kaplony think that the bird in the
serekh of Horus-Bird is the goose sign with the same transcription, "Ba". In this case
Horus-Ba and Horus "Bird" could be the same historical figure. Černý and Kaplony's theory is not commonly accepted; the presence of the Horus-Bird
serekh in the tomb of
Qa'a pointing rather to an interregnum with Horus-Bird between the first and second dynasties. ==Possible battle with Sneferka==
