The roadrunner - AKA The Most Greatest State Bird Ever

Pyrrhuloxia, Cardinalis sinuatus

This adorable bird is the most common in North America with an estimated population of 1.4 billion - that is a lot of birds.  You'll notice that these birds come in two colors, the female will be the grey one and the male will have bright red on his chest. The females prefer to mate with males with the most red, and over generations this trait is selected for resulting in males with more and more red. Interestingly, the males can't actually produce this color on their own, they get it from eating red berries and fruits.

People often make the mistake of applying their moral system to animals, which is made clear when you ask people their opinion of vultures. To eat the dead is disgusting, and for an animal to live off the rotting flesh of the deceased seems to be perceived by people as an act bordering on sin. But nature does not recognize a human morality, and all species that exist in nature exist because it fulfills a need. This concept is made clear when you take a close look at the Turkey Vulture.
