 Thirdly, and more basically, there is no reason why the Twins, being bird-hunters, should not have been involved in more than one bird-shooting episode.As a matter of fact, at least one pottery scene has Hun-Ahpu shooting a vulture.Therefore, rather than referring to the Vucub-Caquix tale, the shooting of the Principal Bird Deity may well represent a now lost bird-shooting episode of Twin mythology.
