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.

@Larry- Thanks! I know, I love hearing the white throated warbler song, but not when it starts around 4:30am...We had some warm weather a few weeks back and I was sleeping with the window open, so yes they were my personal alarm clock :)
@dream falcon- totally! It does look like a little beard. They're so cute.

@Philip- Agreed! Most are brown and difficult to distinguish. Luckily the White-throated has that white beard, and yellow "lores" (those markings by the eyes). They're on the very short list of sparrows that I can identify! ;)
