I really enjoy the White Throated Sparrow song. I recorded some audio of the white throated sparrow song back in November at our friend's farm in Connecticut. I hear them all the time now, especially early in the morning here in Bridgewater when I'm getting ready for work.

The white throated sparrow range has them moving northward pretty soon it looks. They're winter residents here in Massachusetts, according to my Sibley Guide, meaning they'll soon be headed north to their summer territory in Canada it appears.
