I first saw these migrating through this spring. Calling, but not singing. They're alleged to breed here, but I've only encountered them as migrants (I saw a handful more this fall).
The video is mislabeled a bit. Though it's a thrush, the bird is just the "Veery", named after its call note of "Veer". Bonus thrush action after the break...
Wood Thrush.

This is a closer relative of the common American Robin than the Veery, the Twin Cities lie at the northern edge of its breeding range (so we don't get any migrating through). I chanced upon one near Wm. O'Brien State Park in late July (at my son's Cub camp). That one wasn't singing, only calling. My glimpse of the bird flying away from me was very unsatisfactory, and I could not relocate it. Had I not heard it, I wouldn't have been able to identify it.

Closer to the Veery, I've seen them migrating through the Twin Cities, both northbound and southbound, many times. They breed in northern MN. Nibbish could run into them.
Haven't seen any of these our way.
I'd like to. That's a pleasant song.
I haven't heard any of these birds singing myself. But I'm ready to ID them when I do.
My FiL had one/some in Glenwood in early July (either that or slightly-less-likely Swainson's). It/they weren't juveniles, so it was either a male that gave up on his brood (not sure how much the dads contribute to raising the young in that species), or either sex that had a failed brood or couldn't find a mate.
