• The house sparrow survived in the extreme conditions of Halmer-Y village, settling under the roof of a mechanical workshop after arriving in a covered wagon. In the 1970s, it established itself there despite the harsh environment.

House sparrows are distributed across five biogeographical realms: Afrotropics, Indomalaya, Nearctic, Neotropical and Palearctic; the species occupies Celtic broadleaf forests, broadleaf forests of Western Europe, coniferous forests of Mount Cilia, low-lying forests of Eastern Great Lakes, Balkan mixed forests, and Baltic mixed forests.
