How to Identify Birds by Songs : The Song & Calls of the Black-Capped Chickadee

[BugFolk]

I could use some help. I was at the Boundary Waters area in MN and I heard a bird that sounded distinctly like the whistled Fee-bee note, but it went one note lower after the typical 2 note whistle and it repeated the 3rd note whistle in a sort of a Fee bee bee bee bee bee dee. (instead of the scratchy sound) I can't figure out if that is a unique dialect of the black capped chickadee or another bird. I can't find a recording anywhere.

I guess the closest I could describe the sound sort of starting like the black-capped chickadee, but then continuing like the Carolina one, but with one note rather than the varied tone. I notice even in the Twin Cities some Chickadees do the lower 3rd note, but then finish off like the typical sound. I can't seem to find any info about the variation.

"but it's also important to the chickadees themselves." hehe, so cute.

Thank You! That was informative. It was driving me crazy not knowing what that bird was. I LOVE that sound.
