Caruncle (bird anatomy) Caruncle (bird anatomy) 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 (or dewlaps), snoods, and earlobes. The term caruncle is derived from Latin 'caruncula', the diminutive of 'carō', flesh. 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
Dennie–Morgan fold Dennie–Morgan fold A Dennie–Morgan fold, also known as a Dennie–Morgan line or an infraorbital fold, is a fold or line in the skin below the lower eyelid. It can simply be an ethnic/genetic trait, but was found in one study to occur in 25% of patients with atopic dermatitis. The presence of Dennie–Morgan folds is used as a diagnostic marker for allergy with a sensitivity of 78% and specificity of 76%. Such folds are also common among certain ethnic groups such as Blacks, Tatars, Slavs, Balts, and Finno-Ugric peoples and are not known to be associated with any medical condition
