Scarlet Tanager. Male Scarlet Tanagers are among the most blindingly gorgeous birds in an eastern forest in summer, with blood-red bodies set off by jet-black wings and tail. Theyâre also one of the most frustratingly hard to find as they stay high in the forest canopy singing rich, burry songs.
However, a red tongue can be a sign of an underlying medical condition. Some red color changes on the tongue (strawberry tongue) could be related to a vitamin deficiency, Kawasaki disease, or a strep infection (scarlet fever). Erythroplakia is a red patch or lesion that cannot be rubbed off on the tongue (except for the color, it is similar to leukoplakia).
White coated tongue is a common sign of fungal infection known as Oral Thrush. As it is mostly caused by overgrowth of fungus called Candida, this condition is also referred to as Candidiasis of the mouth and throat. The presence of white patches on the surface of the tongue and bad breath are the most common white coated tongue symptoms. The coating can also be yellow or brown in color.
