In the past, sparrows (Passer domesticus or house sparrow) were found everywhere where people are. More recently, however, in some areas they have become so rare that they are now listed in the early-warning section of the Red List of Threatened Species. In cities, there are often not enough available food resources or safe hatching places. Since 2010, March 20 is World Sparrow Day! The city sparrows in this calendar found their habitat in Berlin.
