This is turning out better than expected. It's looking like there will be four, decent-sized aviaries that encompass the old shrubbery border. Viewing will be directly from the path adjacent to the chimpanzees, and housing will be roughly where the mini digger is sitting in this photo.
It seems work is progressing fairly quickly with this project and the enclosures look a decent size when I visited last year didn't see a thing in them so its good to see them getting attention as most bird areas have this year I wonder what we'll in them though
