Hi all
Changes in agricultural practice c. 3600 years ago in Italy apparently made
it possible for the House Sparrows to invade nothern Italy, which was
formerly inhabited only by (migrating ?) Spanish Sparrows, and both
gradually became mixed. Without further major invasions by both House and
Spanish Sparrows, hybrid populations became stabilized (named Italian
Sparrows). Until now, because a new influx or a small invasion of Spanish
Sparrows from the Balcans is in action currently in the Po Delta, NE italy.
Read the history of the return and look at the photos showing Spanish,
Italian, Malta and Crete Sparrows at this Birding Italy link:

One of the best shot is probably this: a rare photo that shows both Italian
and Spanish Sparrows:
