Birds and Rivers
Birds are the most abundant group of vertebrate wildlife in all the natural environments in Spain. Rivers, far from being the exception to this rule, are home to many bird species: some go there to eat, or to nest or to rest, others follow the course of a river, using it as a migratory route to travel between Europe and Africa.
