The red color of the Cardinal’s feathers is the result of pigments called carotenoids. The amount of the pigment ingested, and then deposited in the feathers as they molt in the fall, influences the quality and depth of their red coloration. A study done by the Ohio State University found that juveniles, less efficient foragers than adults, often have a duller red feather coloration.
At the feeding stations the birds tend to prefer seeds that provide the most nutrients. The U.S. Fish and Wildlife Service published a landmark study of bird food preferences in 1980 for several bird species and found cardinals exhibited the greatest preference for fresh sunflower, peanuts, safflower, and millet. They avoid buckwheat, cracked corn, milo, oats, wheat, nyjer, canary, flax, rapeseed, and rice.
Wild Birds Unlimited No-mess Blend is our best selling blend. It has everything the birds want and leaves no messy shells behind. The first ingredient is sunflower seeds with the black shells removed. You only pay for seed not the shells. Birds don't eat the shell. Those are just discarded below the feeder as waste. Because there is no shell, there is about twice as much seed in the bag. Pound for pound it is the better deal and it also should go down twice as slow in the feeder.
Whatever seed, seed cake, or suet you choose at Wild Birds Unlimited, we guarantee it will be fresh and a healthy choice for our local birds.
