Classification: Genus Passer; Family Sparrows (Passeridae)
General: The Spanish sparrow or willow sparrow (Passer hispaniolensis) is a passerine bird of the sparrow family Passeridae. It is found in the Mediterranean region and south-west and central Asia. It is very similar to the closely related house sparrow, and the two species show their close relation in a "biological mix-up" of hybridisation in the Mediterranean region, which complicates the taxonomy of this species.
