Walking by the wetlands at REGUA along the Yellow or Brown trail, a small bird can surprise many with its fierce song of bravado.

One has to peer through the tangles of brush to catch a glimpse of the melodious Long-billed Wren (Cantorchilus longirostris), one of the Atlantic Rainforest endemic species. Though the call is well known, its intensity is surprising but it is merely reminding us that we are entering his territory.

The Yellow and Brown trails at REGUA pass through the middle of replanted lowland forest, and the presence of this species indicates the forest has provided a new home for many avian species.

This is what we want, a new habitat we created that now provides many new homes for its true inhabitants.
