Well that's Bronx for ya! Always changing things around. This is the first time I've seen this species, too, so it's either been off-show for a bit until now or it's new.
I wasn't when I visited. They were working on the roof and in the Hoopoe/capercaillie enclosure when I visited, though (the animals were still on-show, though the screen made it impossible to properly photograph the Hoopoe!).
