A wattle is a fleshy caruncle hanging from various parts of the head or neck in several groups of birds and mammals. Caruncles in birds include those found on the face, wattles, dewlaps, snoods, and earlobes. Wattles are generally paired structures, but may occur as a single structure when it is sometimes known as a dewlap. Wattles are frequently organs of sexual dimorphism. In some birds, caruncles are erectile tissue and may or may not have a feather covering. [1] [2]
Wattles are often such a striking morphological characteristic of animals that it features in their common name. For example, the southern and northern cassowaries are known as the double-wattled and single-wattled cassowary, respectively, and a breed of domestic pig is known as the Red Wattle.
In birds, wattles are often an ornament for courting potential mates. Large wattles are correlated with high testosterone levels, good nutrition, and the ability to evade predators, which in turn indicates a potentially successful mate. Ornamental organs such as wattles may be associated with genes coding for disease resistance. [3] In umbrellabirds, the wattle serves to amplify the birds' calls. [4]

Wattle or wattles may refer to:
The golden pheasant, also known as the Chinese pheasant, and rainbow pheasant, is a gamebird of the order Galliformes and the family Phasianidae (pheasants). The genus name is from Ancient Greek khrusolophos, "with golden crest", and pictus is Latin for "painted" from pingere, "to paint".
The yellow-wattled lapwing is a lapwing that is endemic to the Indian Subcontinent. It is found mainly on the dry plains of peninsular India and has a sharp call and is capable of fast flight. Although they do not migrate, they are known to make seasonal movements in response to rains. They are dull grey brown with a black cap, yellow legs and a triangular wattle at the base of the beak. Like other lapwings and plovers, they are ground birds and their nest is a mere collection of tiny pebbles within which their well camouflaged eggs are laid. The chicks are nidifugous, leaving the nest shortly after hatching and following their parents to forage for food.
Anthochaera is a genus of birds in the honeyeater family. The species are native to Australia and include the little wattlebird, the red wattlebird, the western wattlebird, and the yellow wattlebird. A molecular phylogenetic study has shown that the regent honeyeater also belongs in this genus.
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 reflects that combs are generally larger on males than on females. There can be several fleshy protuberances on the heads and throats of gallinaceous birds, i.e. the comb, wattle, and earlobe, which collectively are called caruncles, however, in turkeys caruncle refers specifically to the fleshy nodules on the head and throat.
A dewlap is a longitudinal flap of skin that hangs beneath the lower jaw or neck of many vertebrates. While the term is usually used in this specific context, it can also be used to include other structures occurring in the same body area with a similar aspect, such as those caused by a double chin or the submandibular vocal sac of a frog. In a more general manner, the term refers to any pendulous mass of skin, such as a fold of loose skin on an elderly person's neck, or the wattle of a bird. Dewlaps can be considered as a caruncle, defined as "a small, fleshy excrescence that is a normal part of an animal's anatomy".
The southern cassowary, also known as double-wattled cassowary, Australian cassowary or two-wattled cassowary, is a large flightless black bird. It is one of the three living species of cassowary, alongside the dwarf cassowary and the northern cassowary. It is a ratite and therefore related to the emu, ostriches, rheas and kiwis.
The crest is a prominent feature exhibited by several bird and other dinosaur species on their heads. It is distinct from features such as casques and cockscombs - sometimes erroneously referred to as "crests", which are bony and fleshy structures respectively.
Shoalhaven Zoo, formerly the Nowra Animal Park, is an animal park on the South Coast of New South Wales, Australia.
The comb-crested jacana, also known as the lotusbird or lilytrotter, is the only species of jacana in the genus Irediparra. Like other jacana species, it is adapted to the floating vegetation of tropical freshwater wetlands.
A caruncle is defined as 'a small, fleshy excrescence that is a normal part of an animal's anatomy'. Within this definition, caruncles in birds include wattles, combs, snoods, and earlobes. The term caruncle is derived from Latin caruncula, the diminutive of carō, "flesh".
A frontal shield, also known as a facial shield or frontal plate, is a feature of the anatomy of several bird species. Located just above the upper mandible, and protruding along the forehead, it is composed of two main parts: a hard, proteinaceous callus and a soft, fleshy corium. It is thought to play roles in protection, mate identification, sexual selection, and territorial defense.
The following is a glossary of common English language terms used in the description of birds—warm-blooded vertebrates of the class Aves and the only living dinosaurs, characterized by feathers, the ability to fly in all but the approximately 60 extant species of flightless birds, toothless, beakedjaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart and a strong yet lightweight skeleton.
