Why is the Male Red Cardinal is so Bright - you may be surprised

Like any avid birder, spotting brightly coloured wildlife is high on my list of goals when venturing into the wilderness. One species that offers particularly colourful plumage is the Red Northern Cardinal – but why are they so brightly colored? The males are among the most recognizable birds in North America, with their brilliant scarlet feathers standing out against green trees, brown branches, and even winter snow. The remarkable red plumage of a male Northern Cardinal is closely connected to what it eats, how its feathers develop, and how cardinals choose mates. So, if you’ve ever wondered why the Red Cardinal looks the way it does – or you’relooking to attract them to your garden– then you’ve come to the right place. A cardinal’s red feathers start with its food The secret behind that unmistakable red color is found in a group of natural pigments called carotenoids. Carotenoids are pigments found in many plants, fruits, and other foods. Birds can obtain these pigments through their diet and, in some species, use them to produce the bright colors seen in their feathers. Northern Cardinals are particularly dependent on carotenoid-rich foods for their red plumage. According to theCornell Lab of Ornithology, the species’ diet includes seeds, grains, fruits, and insects, with berries and other plant foods providing important sources of carotenoids. But it’s more than just eating certain foods that makes the Red Cardinal so bright – it’s how the species processes carotenoids. The bird processes the pigments it consumes and deposits carotenoid-derived pigments into growing feathers. This is one of the reasons the quality and availability of food can influence how intensely colored a male cardinal appears. In other words, that brilliant red coat is partly a reflection of what the bird has been able to eat. Why are male cardinals
