Spoonbill x Ibis Hybrid (?) at Grugapark, 17/06/19

Does anyone know the history of this individual?

Yeah, that's definitely a hybrid spoonbill x ibis.

I took a bunch of photos of similar individuals at Chengdu Zoo (all linked on the second page of comments on the following photo, and there is also the link to another thread about hybrids of this nature):

I had no idea these species could hybridise!
