Sounds like a plot to get us to update our birdsong recordings! :wink:

I've long been aware of geographical differences but never thought they might change over time.  Now that I have thought about it, I guess it's not really that surprising.  It will be interesting to see how it changes (or changes back) over the next 30 years.
