"Just" a little House Sparrow

I love photographing these birds when I get the chance. They have such a beautiful feather pattern. Like this photo, many of my House Sparrow photos have been taken at the Calgary Zoo. This one was seen at the Zoo on 21 September 2015. The House Sparrow is an introduced species here. Is this bird a young male?

"One of about 25 species in the genus Passer, the House Sparrow is native to most of Europe, the Mediterranean region, and much of Asia. Its intentional or accidental introductions to many regions, including parts of Australia, Africa, and the Americas, make it the most widely distributed wild bird." From Wikipedia.
