While I was in Atlanta, I read a New York Times story about birding apps for iPhones and the like. (Until I get another job, I can't afford an iPhone but I'm lusting after one.) The article says that developing an app that identifies birdsong is problematic because birds have regional "dialects."
That was a coincidence because I'd been listening to the breeding song of the cardinals in Atlanta and it was noticeably different from those in Miami, 700 miles to the south. The song in Miami has a higher pitch and is faster.
Has anyone else noticed the same thing with cardinals or other birds?
Seeing Gardens Differently

Do you really “see” the gardens you visit? I mean, do you see what the
creator of that space wanted you to see? Do you see it the same way
others do?...
