Well, I'm not a hornbill expert, but ZTL Lists the wrinkled hornbill as the only Asian hornbill outside the hornbill aviaries. There was also still a knobbed hornbill and signage for the knobbed hornbill still in the Hornbill aviaries in the beginning of the park
@Mr Gharial I'm not sure where to view the zoo location information you reference, but having seen both Knobbed and Wrinkled multiple times I'm quite certain of the ID. The blue throat, all white tail, and larger size are enough to easily separate it as Knobbed.
@Great Argus The knobbed hornbill signage, as well as a knobbed hornbill, were at the hornbill aviaries near the beginning at the park. ZTL also lists the knobbed hornbill as being in the hornbill aviaries.
ZTL doesn't list the wrinkled hornbill as being in the hornbill aviaries. And I found this one, without signage, in the toucan aviaries near the exit of the Gorilla adventure and the entrance to the tiger tunnel
@Mr Gharial I saw this bird myself last week and can confirm this is a knobbed hornbill. Judging by the appearance of this bird I thought it is probably a chick of the pair in the hornbill aviaries. The wrinkled hornbills are in the first of the hornbill aviaries as seen from the entrance. I saw them there myself last week.
Fair enough, I've changed the title. Though I think it would make more sense if this was one of the parents and the chick was with the other parent in the hornbill aviaries. As this one looked quite old with some very aged wings (see the other picture where the bird is flying, you can see it's missing some feathers)
@Mr Gharial the missing feathers is probably a sign of moult, which is something a bird does regularly throughout its life. I based my impression that this was a young bird on the shorter bill and less-vibrant colours of the bill and casque in this bird compared to adults I have seen. But I could be wrong ofcourse
