Central Savannah, a rural and suburban region that surrounds Bogota and its eight million inhabitants, struggles against urban sprawl. Landscapes at the brink become a universe of borderlines between nature and human presence, which can be barely perceivable or very aggressive, clearly real and abstract at the same time, but always a space of mutual recognition. In this universe a caw is just a living been at the edge of a mountain, it is not the representation of the extensive livestock farming that has been recognized as environmentally harmful, and the housing constructions climbing mountains can become an appealing landscape or the landscape of the horrible urban sprawl. The caws are not the problem, the houses on the hill either. But how far will it go?
