In Malaga wagtails are known as "pipitas", probably because of the typical call they make when flying. The Western Yellow Wagtail is traditionally associated with cattle, hence the name of the species in Spanish: "lavandera boyera", which in English stands for "drover washerwoman". It was a regular visitor of the pasturelands and meadows used by cattle.
