Got Cardinals?

Every afternoon when I go out to put out the birdseed cardinals gather in the wisteria that is climbing over what remains of a big old red oak tree. I sprinkle the seeds, turn and head back into the house, and look behind me to watch a veritable swarm of cardinals arrive for their evening meal. I took this photo once I was back inside - through the window - and I think I count 15 cardinals. Seven males, eight females. Plus two white-throated sparrows. Mind you - there were also other cardinals on the ground below the maple tree eating when I took this shot. I've tried to count on many occasions, but it's impossible. All I can say is, we've got LOTS of Northern cardinals at our house.
