I have lived in the Graham-Eatonville area for 22+ years. While I have not
been a birder for more than half of those years, I must say that I have
witnessed many changes in all animal life, not only bird life, as my rural
area has become more suburbanized. Only in the last six or so years have I
seen starlings on my 9 acres. Unfortunately they have taken over my wood
duck nests. They are only present in the spring to nest and fledge their
young, and then leave. They dive bomb the ducks each spring until they
drive them off of there historical nesting area. As of yet, I have not ever
seen a house sparrow on my property or even in the area. I would trade
house sparrows for starlings any day. My experience would however support
your theory that increasing human habitation increases these species.

I would add however that whenever you travel in rural areas where dairy
farms are present, no matter how remote they are, it seems that large
numbers of starlings (and often time rock doves) are present. This holds
true in my observations traveling all over the west, not only in Washington.
I am sure they have found an easy meal in spilled grain. Birds are very
smart when it comes to being fed.

I must admit I have been a 'lurker' for a few months on Tweeters, and thanks
to Tyler have felt that I should respond to messages that I might be able to
contribute to. Thanks Tyler and Michele for getting me to get into a more
responsive mode.
