What Food Makes A House Finch Red?

Why are some House Finches more red than others?

Though we typically think of House Finch as red, they actually come in a few color variations. Different subspecies may show color variations, but differences in color are also attributed to diet. When a bird is molting, its diet will determine the colors of its new feathers.
