I saw my first Bluebird of the season on Tuesday.
Dont know what this is but we shared lunch at the ski resort lodge yesterday. He is tagged so someone is keeping an eye on them

I'm in northern Illinois, and we have a plethora of birds at the feeders and the wetlands next to the house, but this summer we have been seeing a TON of European Goldfinches.
They are not indigenous to the U.S., and there is conjecture that released pet store birds have been breeding here.
There are just too many of them to be released birds.
You might have a localized breeding population near you, Phil. If the conditions are right, it wouldn't take too much time for a sizable population to grow, even from some released birds. This is what happened with house sparrows, European starlings, and house finches.
In any event, this person might be very interested in your sightings:

Drop him an e-mail. Sometimes the best statistical info comes from backyard observers.

P.S. - They're sharp looking birds. Wouldn't mind having some in my backyard!
