Ah the snood. That fleshy protuberance that hangs down over a wild turkeys beak. On males Turkeys the snood can grows up to 5 inches in length. When a male is trying to impress a female the snood turns bright red and elongates even further. The males with the longest, brightest snoods tend to attract the most mates.
Here two males are in full display mode however it is curious that one of the males snoods is blue the other red.
While mature female turkeys develop a short snood three evolutionary function remains a mystery.
