The head has fleshy growths called caruncles. Pathology studies are necessary to distinguish carcinoma of the urethra from urethral caruncles. Falco's body feathers are blue, with red caruncles around his eyes. It manifests as three connected rows of caruncles in the form of conjoined pea-like protrusions. They are dumpy, short-necked, pigeon-like birds with white plumage, black bills, caruncles and facial skin. Both sexes of turkey possess caruncles, although they are more pronounced in the male. The 3 lateral caruncles have club-shaped glands that secrete a slime containing luminous granules. Caruncles can grow back in some instances. Urethral caruncles can accompany the skin changes related to lowered estrogen levels. They have no caruncles, and their eye-rings are lead-blue. Yellow-orange swellings (caruncles) are found above the base of the bill. The caruncles can be removed by surgery, electric cauterization and then with suture repair. The caruncles are yellow, the eye-ring blue, the mouth orange and the bill is light-grey. Caruncles in birds include those found on the face, wattles, dewlaps, snoods and earlobes. Caruncles may be featherless, or, have small scattered feathers.
