House Sparrow vs Italian Sparrow

In short

The Italian Sparrow (Passer italiae) and House Sparrow (Passer domesticus) are both members of the sparrow family but can be distinguished by differences in plumage, size, and habitat preferences. The Italian Sparrow typically exhibits a more muted coloration with distinctive facial markings, while the House Sparrow is more variable with a broader distribution and adaptive behaviors in urban environments.
