Right at the entrance you can see the feeder, the pond and some fruits that are put on tree trunks, the birds keep flying around this area but avoid it when people are nearby.
I've seen somewhere it holds around 20 bird species, but they are not identified. I'm not experienced in identifying birds, but I believe I've seen Red-winged Tinamou (Rhynchotus rufescens), Creamy-bellied Thrush (Turdus amaurochalinus) and Blue-winged Parrotlet (Forpus xanthopterygius). I've seen more, just couldn't identify, I'll keep going there and taking note of what I see.
