Update 1 (29 March 2013):
Breeding evidence! An incubating House Bunting photographed at the same place where the species was observed last year (near the Faculty of Science, see photo 2).
Update 2 (30 May 2013):
As expected (see the last 2 paragraphs above before update 1), the House Buntings were already breeding at the Medina of Tétouan since a few years, but we didn't know about them. The locals of course know them and know that they are new here. The new evidence came from photographs (photo 3) taken in the Medina of Tetouan and uploaded to Facebook by Al-Hassan Bebnouna on 14 and 27 October 2010. According to the observation of Al-Hassan, these birds are very tame and come very near humans in search for food. It was his son, Soufiane, who alerted us by sending the link of the photographs that his father shared on his facebook nearly 3 years ago.
