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).
Learn the signs and causes of a strawberry allergy. These include blood dilation, fluid secretion in exocrine glands, muscle spasm and others. This allergy is due to the presence of a protein that gives that enticing red color to the strawberry. The protein was isolated by researchers from the University of Lund in Sweden. Eating white strawberries avoids the allergic reaction, but the taste is not nearly as delicious.
