Macaw Colpa


    Rising up from the waters of the Las Piedras River, this open clay cliff-face is frequently visited by large numbers of macaws and parrots (up to several hundred a day!). These beautiful birds flock together in the giant trees above the colpa, chattering and jostling for space. They swoop down to the cliff where they use their beaks to gouge out and gulp down the clay. Why they do this still remains a mystery but recent studies suggest that the clay may provide them with vital nutrients or even help to calm an upset stomach!
