More fun with bird songs

[paulhu...@gmail.com]

Here is another recording from this morning at Tyson Bend in Harrison County.
After listening to this at home, I’m pretty sure the culprit is a black capped chickadee, but at the time I was pretty sure I had a white throated sparrow singing. The first two notes sound like a black capped chickadee, but the bird holds those notes a little longer than I think a chickadee would, and there’s a thrill at the end, which to me sounds just like a white throated sparrow. This recording is fairly long, and you can hear my fishing rods and paddle bouncing around in my kayak for which I apologize.
Do you think it’s just a black cap chickadee who has jazzed up his song?
Thanks again
