The life that surrounds Nicaragua's active Masaya Volcano is examined. Included: bats that have colonized the miles of tunnels created by hot flowing magma; and parakeets and vultures that have made nests inside the crater. Also: vegetation that, over hundreds of years, has recolonized barren stretches on the volcano's flanks; and the fields, pastures and towns that have grown over the oldest lava flows.
