In anatomical terms, the
snood is an erectile, fleshy protuberance on the forehead of
turkeys. Most of the time when the turkey is in a relaxed state, the snood is pale and 2-3 cm long. However, when the male begins
strutting (the courtship display), the snood engorges with blood, becomes redder and elongates several centimetres, hanging well below the beak (see image).
