I am wondering if that red bald patch, which is on both males and females, is used for attracting the opposite sex. (Apologies for the photo quality as this was a quick hop out of a car while with friends.)
They have been documented flying over Mt. Everest at 28,000 feet, so I tip my hat to their stamina and aviation skills! According to Florida DNR, there are about 5,000 of these that remain in the state year-round, but they can be found all over the United States as some are migratory and there are six subspecies. Maybe one of these days I will be there for their season of dancing.
On my bucket list is to see the mass gathering of them on the Platt River of Nebraska in the spring or to see them at the annual Sandhill Crane Festival in Albequerque in November.
