A bird of the Northern coniferous forests. This one was killed by a car as she moved through Sewanee on her southward migration. Even in death her feathers were stunning.

I just listened to the call, so high-pitched and delicate in contrast to the drama of the feathers.
Yes, their call pushes the limits of our hearing abilities. Like the feathers, it conveys a sense of condensed energy.
