Yоu аre оbserving birds аnd see а Scarlet Tanager, a sоngbird with bright red feathers on males and duller feathers on females. You notice some males appear to be a more vibrant red than others, and wonder if that has anything to do with what they eat. You catch several males and bring them into a lab. For two weeks, they are all cared for under the same conditions and have the same diet except half of the males are given food with more carotenoids in it, a red pigment found in fruits and vegetables, and the other half are given fruit with the same caloric and nutritional value except they do not have carotenoids in it. After two weeks on this diet, you measure red pigmentation of the feathers to determine if there are differences in the “redness” between the two groups.
