Comb (anatomy)
A comb is a fleshy growth or crest on the top of the head of gallinaceous birds, such as turkeys, pheasants, and domestic chickens. Its alternative name cockscomb (spelling variations abound) is because combs are generally larger on males than on females (a male gallinaceous bird is called a cock). There can be several fleshy protuberances on the heads and throats of gallinaceous birds, i.e. comb, wattle, ear lobes and nodules, which collectively are called caruncles, however, in turkeys caruncle refers specifically to the fleshy nodules on the head and throat.
