and become a professional naturalist. Barbour had been accompanied by Cervera on his previous visits to Cuba, and on hearing of the strange birds to be found in the Zapata area, he sent the Spaniard on a series of trips into the region, eventually leading to the finding of the wren. In Spanish, the wren is known simply as ''ferminia''.
