The 5 species at Guayllabamba should be western Santa Cruz porteri, Volcan Alcedo vandenburghi, Cazuela guntheri, Volcan Darwin microphyes and Piedras Blancas becki.
I think they had several corrals and possibly the porteri group (there should be 4 I believe) has an enclosure of their own. Would be helpful to have some operational breeding programs in the country's mainland zoos and facilities.
