I'm not entirely sure what this is. But I think I see some characteristics of both a sacred ibis and a straw-necked ibis, and the animal does not match the adults or juveniles of either species. If someone can tell me please let me know.
One parent is definitely a Straw-necked Ibis. The other is probably a Sacred or Oriental Black-headed Ibis (depending on what the zoo keeps). It would be extremely unlikely to be a hybrid with a Scarlet Ibis - they are different genera and there is nothing about this bird to suggest Scarlet Ibis.
@Chlidonias The zoo keeps straw-necked and sacred ibis and the species have been housed in the same aviary or may still currently be, so logically one would assume it is a hybrid of those two.
