Well, I'm a North American (at least, by adoption) and maybe not that knowledgable but I can tell you that E. Starlings are extremely numerous in Canada to the point that many birders refer to them as flying rats. I know of one bridge where it is extimated that 10000 Starlings roost every night.tp20uk said:Thanks pete. Where are all you knowledgable Americans??
tp20uk said:You are fortunate (or not, whichever way you want to think) that there are so many. In Britain they are in decline, and I haven't seen a flock of House sparrows for ages! I see one or two every now and then. The RSPB has statistics.

The Rock Dove is another introduced species that we could have lived without.
