I have some horrible phone snaps of the signage of the free-roaming animals in August 2016, and there's no leafbird in there... I definitely hope it's still around!
The species signed then were: fody, snowy-crowned robin-chat, red-eared bulbul, brazilian tanager, chestnut-backed thrush, white-rumped shama, blue-black grassquit, rose-bellied bunting (twice, oddly enough), white-eye, timor sparrow, purple honeycreeper, screaming piha, speckled mousebird, red-crested turaco, asian fairy-bluebird, red-rumped cacique, pheasant-pigeon, sunbittern, crested partridge, blue-crowned laughingthrush, african darter, brazilian teal, white-faced whistling-duck, scarlet ibis, crowned pigeon, pied imperial pigeon, pinon's imperial pigeon, nicobar pigeon, gray's piping-guan, emerald dove, bleeding-heart, green iguana, green basilisk and guadeloupean anole.
