House Sparrow

I loved the sheer fluffiness of this sparrow, Whether this means it is a juvenile with its early downy feathers still to drop out I am not sure. I think this is a house sparrow but the italiae version, which is a hybrid with the Spanish Sparrow but I am open to any advice here. It is not often that we get house sparrows at our garden feeders so they are a little unfamiliar to me. Although they are among the most common of British birds their numbers are fast declining, by as much as 71% since 1971.
