I LITERALLY JUST BROKE OUT INTO A COLD SWEAT HOLY CRAP DUDE!!!!!!!!!!!!
Who was the person doing the bird imagery?! GET ON THIS STAT!
From a very basic google search
Cardinals come from the word ‘cardo’ which means ‘hinge’. It’s important and other things 'hinge’ around it.
The cardinal is a 'daughter of the sun’. If it is seen flying upwards it is a sign of good luck. Downwards symbolises bad luck. That cardinal did fly DOWN to Bill…
From the first link about the birds when you google 'cardinal symbolism’. I’m sure others can do vastly better than this though!
