I believe Patrick and Ruth Sullivan mentioned yesterday about a Western Scrub Jay near Randle and they surmised that the bird's appearance in that area might represent a range expansion...what are some other birds that come to mind that have undergone either small- or large-scale range expansions? I can think of a few, such as the Barred Owl, House Finch, and other obvious candidates...American Crow, European Starling, and House Sparrow...but I'm sure there are others. Any thoughts?

A child who becomes acquainted with the birds about him
hears every sound and puzzles out its meaning with a cleverness
that amazes those with ears who hear not.
