Have you ever heard a piece of birdsong in the morning and then been unable to get it out of your head? It seems odd to call this kind of song an earworm, but that’s what it is. I was out with Cricket and Butterfly, and this bird just kept singing, over and over, until I found myself trying to sing along. First, I tried to whistle the song, but my whistling skills seem to have dropped off over the years. So then I tried to sing it, but it was early in the morning and my upper register was not awake yet. As a result, my version of this bird’s song was an octave lower, slower, and maybe a bit jazzier than the bird intended. It’s possible that the bird wouldn’t even recognize his song the way I sang it.

“I hear birdies.”
After getting rid of the poopy bags, washing my hands, and giving the girls their morning dental treats, I sang the song to Mom (she is basically a savant when it comes to the names of birds and plants, just don’t ask her to remember the name of a person she has known for twenty years). Mom went to her best friend, Google, for help, and she found a bird song website. We listened to the songs of all of the possible suspects, based on who she knows to frequent our yard, and I said, No, No, Nope, Not even close, until she found the singer. The website said that the White-Throated Sparrow has two songs: one that goes up, and one that goes down. The one I kept hearing was the one that goes down.
Mom took out her trusty recorder to help me figure out the starting note, which turned out to be F over High C. When my voice is warmed up I can hit G above high C, but that early in the morning it was a challenge. And of course, as soon as I finally managed that F, Cricket duplicated it without a problem.

The singer!
The whole idea that a website can capture all of the birdsongs, because each type of bird has only two or three songs in her repertoire, and sings these same songs over and over again, for the rest of her life, boggles my mind. I wonder what would happen if a baby bird, trying out her voice for the first time, accidentally sang a different song from her parents. Is that what gets babies kicked out of the nest prematurely? Or are baby birds physically incapable of that kind of heresy? Maybe it’s like a pre-set recording in the bird’s throat and any time he tries to speak that song is the only thing that comes out.
Then there’s the Mocking bird, who can mimic any other bird’s song, which is kind of like doing Karaoke for your entire life. Is that better?
I originally thought that the singing bird might also be one of the birds building a nest complex under Mom’s air conditioner. It’s a couple, actually, and Mom gave them a handful of colorful scraps of fabric, to help with their interior decorating, but they are still busy with construction, adding room after room to this McMansion of a nest. The nest builders are Sparrows too, but from another sect. Maybe the singer is the construction manager, giving his orders from on high! I’ll have to be more careful singing along to these bird songs in the future. Who knows what kinds of messages I’ve been sending to the bird population without realizing it?! Wait, what if they all think that I’m a Mocking bird?!

“You’re not the mockingbird, Mommy. That’s MY job.”

The very busy birdie.
