Here at my home in Duluth, MN, I have observed Tennessee Warblers coming through in the fall on their way to Central America and the Caribbean. They aren't the easiest birds to identify without binoculars. I've seen them up high in birch trees and lower in tall grasses. They spend their summers up north breeding in Canada's boreal forests and spruce bogs, laying between 4-7 eggs.

These birds are not aptly named. The only reason these birds are called Tennessee Warblers is because ornithologist Alexander Wilson discovered this bird in Tennessee. He might as well have named it Jupiter because it doesn't have anything to do with Tennessee, or 99% of North America for that matter. It may breed in northern Minnesota and Wisconsin, and also the far reaches of northeastern United States. Okay, yes it migrates through Tennessee. Sorry, doesn't count, Mr. Wilson. For shame.

In this painting, the Tennessee Warbler is perched on a goldenrod, exactly where it was when I noticed it on September 5, 2018. Goldenrod is a tall, yellow, native wildflower that blooms in late summer. In several areas where I have eradicated invasive Common Tansy, this beautiful plant has returned with gusto. If you're one of those people who consider goldenrod to be a weed, take note. Bees and butterflies love this plant.

Tennessee Warblers sing their entire song above 4,000 hertz. In layperson's terms, this means it's simply doggone high. The highest octave on a piano is in this range. Humans sometimes have trouble distinguishing differences in pitches at this level, so based on pitch alone, the song of the Tennessee Warbler may be difficult to differentiate from other birds, several of which also sing in this range.

Do you remember the song 'Lovin' You' by Minnie Riperton? When I was a kid, that was a hit on the radio. Minnie sang part of the song in the second highest octave on the piano, an F sharp in the 6th octave. That's crazy high. In fact, it's so crazy, there's a special name for it: the whistle register. It's the highest register of the human voice. As a youngster singing along to music on the radio, I tried to mimic Minnie whenever I heard that song. With little effort, I nailed those high notes. I am totally kidding people!! In another one of her songs, 'You Take My Breath Away', she went even higher and reached the seventh octave, driving home an F7. I can just hear those pop bottles shaking in the garage. Remember, this is the same octave as the Tennessee Warbler. Holy smokes, y'all. Whoa.

I hope you enjoy this painting of a Tennessee Warbler.
