I didn't have idea SeaWorld acquired this species. During my visit there was absent, tough it was some days after I saw it for first time in my life, at San Diego zoo. I suppose that the SeaWorld specimen(s?) comes from SD zoo.
@Kakapo They were unsigned in a rather uninspiring little aviary, which seemed very easily missable, so perhaps you missed them there? At least you saw them at SDZ though, they’re a lovely species
