They don't have all of these birds in the signages as these are some old labels, but what's interesting is that they instead have rarities like the Malayan black eagle (Ictinaetus malayensis) and Sulawesi serpent eagle (Spilornis rufipectus). Wouldn't hurt to build an bird-of-prey exhibition instead.
@Fargusno I'm very aware, I visited last year. Called "Bird of Prey Kingdom", the aviary being rather small are of course unsuitable for eagles and co.
