The House Sparrow south of Bellinzona

The House Sparrow occurs in Ticino in a hybridisation zone with the Italian Sparrow, which extends from the Gotthard to the Bellinzona area. All individuals south of Bellinzona are Italian Sparrows according to current knowledge and should be reported as such.

Here too, some males may exhibit characteristics of the House Sparrow; in this case the entry "Italian x House Sparrow" may be selected.

If you see a "pure" House Sparrow south of Bellinzona, we would be grateful for photo evidence.

Thank you very much for your cooperation!
