Sandhill Crane
What bird can lift the most?
A crane.
Interesting Fact: The Sandhill Crane’s call is a loud, rolling, trumpeting sound whose unique tone is a product of anatomy: Sandhill Cranes have long tracheas (windpipes) that coil into the sternum and help the sound develop a lower pitch and harmonics that add richness.
