Forty years ago the stork raised in Spain and then made a migration to areas south of the Sahara where it fed during the most hostile period, to return for the current dates honoring the popular saying. However, the saying "For San Blas, the stork you will see" has not been true for years, because this species no longer migrates. The reason is that in Spain there is plenty of food in the garbage cans and water in the irrigated areas , also during the winter period, according to SEO / Bird Life.
Likewise, the idea of making a migration of thousands of kilometers and crossing areas such as the Strait of Gibraltar "which involves a significant effort" makes the storks opt for the safest option, staying in the nest, and not precisely the climate change , with which "a correlation has not yet been detected."
