Yesterday I posted a song sparrow. When I was researching its song on the Cornell site, I double checked that I hadn't confused the song sparrow with the white throated sparrow. I hadn't - but was reminded how much I love the white throated as well. I've only seen one up close once, but I still remember it (I was doing dishes and it was foraging in the leaves outside my window). Here's its song from the Cornell Lab. I hope you check out the Cornell site - it's quite wonderful if you're a birder, probably even more so if you're an amateur like me.
