The cardinal is a representiave of a loved one who has passed. When you see one it means they are visiting you.They usually show up when you most need them or miss them. They also make an appearance during times of celebration as well as despair to let you know they will always be with you. Look for them, they'll appear.
Portrait of a male Northern Cardinal... we have a family of cardinals nesting outside of the kitchen in an actual bird cage we were using as a planter. The babies just hatched and they are such good little parents!
