Did some research on Zootierliste and the only Honeyeater kept during this period at Antwerp was the Wattled honeyeater - aka Red wattlebird ( Anthochaera carunculata ) so I guess it's this species on the picture, Anybody which can confime this ?
Thank you Hix ! Now I'm seeing the name it sounds familary and I think you are right. Zootierliste however only mention London as being a former holder of the species but - as we all know - Zootierliste is not always acurate.
