Male northern cardinals definitely have the spotlight when it comes to North American birds. They're beautiful and highly recognizable. Interestingly, their color can signal certain things about them - not just feather color but also beak color.
But beyond color, their mask size can be an indicator of the type of mate and father he will be.
Furthermore, while color plays a role in dominance, it is not the only factor. One interesting characteristic of how dominant a cardinal is is based on how close he is to his territory.
You might be surprised to find out that color may not play as high of a role in mate selection - however researchers are having a hard time studying that.
His call can also give neighboring cardinals information about himself - for instance, how new he might be to the territory.
And his call has been found to be more adaptable to surrounding environments compared to robins.
In the case of leucistic birds, many studies report their ability to still find mates with females of healthy plumage.
