Lovely yard, Sass! I am a fan of cardinals, too, although my condo association has banned birdfeeders, dammit, so I don't see as many as I once did.
Have you named yours?
I like this little blurb that I read online:
" A cardinal is a representative 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."
