I only knew English sparrow until some years back. I figure the English don't want that dirty bird associated with them. Seems ours in Canada did come from England probably with my grandfather. There are many in Edmonton only 15 miles from me and practically none where I am on my acreage - thankfully. I have no idea why.I had to search the web for the "English Sparrow" - if you mean "House Sparrow" (as I know it) we have plenty. It deserves the name "World Sparrow"!
Concerning the "invaders" - yes, I'm invader in both: Canon rumors (just few years) and Hawaii (more than 18 years), but I'm feeling pretty much home in both!
Your CR invasion has shown up us Canonites! So, hopefully you'll stick around.
