Most House Finches are red. However, its color comes from the food it eats during molt. Orange and yellow house finches can occasionally be seen.
I am sharing images of 2 male House Finches. These are very common birds whose range includes all the continental United States. One of the 2 images shows a bird with a red head and neck: the predominant color for these birds. The other showed up in our backyard a few weeks ago with this beautiful coppery-orange colored head and neck. It wasn’t the effect of the lighting; it was true color. I researched this condition and learned that House Finches can also come in Yellow. It all depends on what they ate or maybe they didn’t eat. The color derives from organic pigments known as carotenoids.
