@ShonenJake13 true, but as a regular visitor it feels like less birds are in there, and less animals in general.
@Joker1706 They are still there yea, but 90% of the day they are just in their cave sleeping, so not much to look at besides some Aardvark back
And that, is exactly why the Bush is my favourite rainforest biome I have visited so far.
When you go out to the real rainforest (which I have), the animals aren't all just there on a plate awaiting your arrival. You have to find them, not the other way around.
I assure you there are plenty of birds in the Bush, but that is what I love about it; the thrill of having to search for a species I might not have seen yet/before (the catbirds, chachalacas and leafbird continue to evade me), and not knowing what may be around the corner. One such example; when I last visited (with @vogelcommando and @korhoen) we were so busy trying to spot all the species that we very nearly missed a few anoles sitting on a branch, and a screaming piha chick in the nest. It's things like that that make the Bush so special.
The aardvarks are a hell of a lot more active than in other zoos I visit (London, Chester etc.) and that's another great thing about it; are you going to see them active today? Who knows, but let's go and find out and maybe we'll see something special like a catbird or the leafbird or even one of the insanely elusive frog species in the Bush on the way.
I haven't seen every species in there yet, nor do I think I will see every species in the Bush in one visit ever. But to say that just because the birds are proving to be a little bit more elusive and that the larger animals aren't as active does not mean that the animals aren't there.
