Resumen:
The role of migratory birds as dispersal agents of snails was hypothesized by Darwin as anefficient long-distance transportation1 (except of human interference), since a migratory birdcan cover hundreds km in few days. Galba truncatula is the most efficient vector of Fasciolahepatica. This freshwater snail, of European origin, was introduced to the Bolivian Altiplanowithin the last 500-year period2-3. Recently, this species has also been described in Andeansites of Mendoza province, Argentina, as far as 2,000 km south 4-6. This poses the questionabout how the considered most pedestrian of creatures reached so far southward.According to Darwins hypothesis, migratory aquatic birds may be counted as one possibilityamongst the probable spreading ways.
