Cliffs ?!

We're very excited to add the cliff flycatcher (Hirundinea ferruginea, gibão-de-couro) to our list ( It's bird species number 401 ! The flycatcher was first sighted by William de Jong, a dutch biologist.
The only question is; where are the cliffs ?!

And by the way, Birdlife International has considered this area one of the Important Bird Areas (IBA BR156) of the World.
