Northern Cardinal

Northern Cardinals are omnivorous, eating seeds, fruits, and insects. Their color is derived from carotenoid pigments from their food. The brighter the male, the better is his reproductive success. Brighter males have richer territories and are better able to feed nestlings (Ikin and Linville 1999). This cardinal, photographed on Tuesday, certainly seems to be a top-dog male. Sometimes we don’t appreciate the beauty of our most common birds—imagine if this were the first time you ever saw a cardinal!

  1. I was thinking that same thought about both cardinals and mallards recently.
