 Barbour had been accompanied by the Spaniard on his previous visits to Cuba , and on hearing of the strange birds to be found in the Zapata area , he sent Cervera on a series of trips into the region . Cervera eventually found the rail near the very small settlement which is commemorated in the Spanish name for the rail , " Gallinuela de Santo Tomás " . Cervera also discovered the Zapata wren and the Zapata sparrow , and his name is commemorated by the new ecological centre in the Ciénaga de Zapata National Park .
