Caruncle (bird anatomy) : ウィキペディア英語版 | Caruncle (bird anatomy)
A caruncle is defined as 'a small, fleshy excrescence that is a normal part of an animal's anatomy'.〔(【引用サイトリンク】title=Definition of caruncle )〕 Within this definition, caruncles in birds include wattles (or dewlaps), snoods and earlobes. The term caruncle is derived from Latin 'caruncula', the diminutive of 'carō', flesh.〔(【引用サイトリンク】title=Caruncle )〕 ==Taxonomy== Caruncles are carnosities, often of bright colors such as red, blue, yellow or white. They can be present on the head, neck, throat, cheeks or around the eyes of some birds. They may be present as combs or crests and other structures near the beak, or, hanging from the throat or neck. Caruncles may be featherless, or, have small scattered feathers. In some species, they may form pendulous structures of erectile tissue, such as the "snood" of the domestic turkey.〔(【引用サイトリンク】 title=Caruncle definition )〕〔 〕 Caruncles are sometimes secondary sexual characteristics, having a more intense color or even a different color, developing as the male reaches sexual maturity.
