Shamefully, the only one of the four passerines you uploaded to the identification gallery, that I cannot identify by memory. It could be a juvenile dacnis but... I'm a bit lost with this one.
The eye color and plumage reminds me of a Green-Backed Camaroptera (Camaroptera brachyura), but I'm not sure if this species is even held by DWA, nor am I sure why they would keep an African species in a South American themed exhibit. Nevertheless, this is my best guess.
@Coelacanth18 I'll mark it down as White-crowned Manakin (Pseudopipra pipra) then. This exhibit does not have any signed species, but it is a monotypic genus and this individual certainly looks like juveniles of this species. Thanks!
@ChunkyMunky pengopus That's odd; I have a photo of the signage from 2019. Funny enough, now that I've checked it the White-crowned Manakin is on there with a dead-on photo of the individual itself!
@Coelacanth18 Was the signage digital or physical? There was an odd-looking spot on the wall next to this exhibit which seemed like where signage had been.
