Illustrator David Sibley and actor H. Jon Benjamin will face off in the bird illustration battle of the century during BirdNote's Year-end Celebration and Auction!
In a clearing where an ancient Mayan city once stood, the Montezuma Oropendola perches and sings. His courtship display is astonishing: he swings by his feet and sings, his tail describing a golden pendulum – the very source of his name in Spanish – oropendola.

Montezuma Oropendola - The Golden Pendulum
Written by Bob Sundstrom
This is BirdNote.
[Montezuma Oropendola song]
On a winter morning in the Central American tropics, the sun rises. In a clearing, surrounded by dense forest, stand the ruins of a Mayan city. And on the warming air, this song:
[Montezuma Oropendola song]
Perched beside its nest is the author of those gurgling tones – a Montezuma Oropendola. He sings again, this time with a sound like the pop of firecrackers.
[Montezuma Oropendola song, with firecracker notes]
The 20-inch-tall male Montezuma Oropendola is feathered in rich chestnut brown. He's an oversized cousin of orioles, wielding a sharp spike of a bill tipped in red. As his song display begins, he grasps a branch in his feet, bows forward, and then hangs completely upside-down, wings fluttering. His long tail becomes clearly visible, bright yellow, pointing upward.
Our oropendola's now suspended head downward, swinging by his feet, singing. His tail describes a golden pendulum – the source of his name in Spanish – oropendola.
