Sandhill crane

"Okanogan County is fortunate to be one of the few places in Washington where one can regularly see - and hear- Sandhill Cranes each spring and fall as they migrate. This past weekend a large group was seen flying south above Winthrop and Twisp. It was spectacular! While large flocks of them are known to stop in and around Othello, WA every March, here in Okanogan County you can count yourself pretty lucky if you ever see one on the ground, taking a break in a cut corn or hay field, or stopping over briefly at a wetland. Mostly, it's the unique bugling call we hear first, and then we look up knowing it's something odd and special, and see anywhere from a single crane to hundreds of cranes. What a sight! But that sound is so bizarre. How is it made? Sandhills make at least 20 different vocalizations. The loud, rolling bugle or trumpeting sound is thought to be used to organize groups and keep everyone coordinated in flight and on the ground. Inside their long necks is a long trachea that coils into the sternum and develops the interesting harmonics and low pitch of the honking bugle call that catches our attention. "
