The Veery thrush has the ability to produce a flute-like sound of 2 notes at the same time.

Veery - This small forest thrush gets its name from its ability to produce a flute-like sound of 2 notes at the same time.

The song of the Veery is one of the most magical and exquisite in the bird world. It is an ethereal downward spiral of flutey notes with an echoing, ventriloquial quality. Frank Chapman, the author of "Bird Life" (1897), had this to say about it: "The Veery's mysterious voice vibrates through the air in pulsating circles of song, like the strains of an Aeolian harp."

1. For years...

... I've called the Veery Thrush the "Pinball Bird", because the call reminds me of sounds pinball machines used to make in the long ago. I've never seen one, only heard them, but now, after decades of wondering, I can finally put a face to that eerily beautiful birdsong!
Thank you, Donkees!

or his website. I immediately checked it out to see if he had clips of my beloved wood thrush! Happily, yes! More than one entry! 😊
