I love those little guys too Hazel, when they see me coming with the seed pail to fill the feeders it's like their internal radar goes off and a slew of them come flying in....some patiently wait, while others decide that I'm taking too long to get cracking and go into the pail and take their pick......we have oodles. I have never tried to count how many, but will....
just to see if I have more than you 
One thing I have noticed for the longest, always the Cardinals are the first to come in the morning and the last ones in the evening, it never fails, sometimes I can hardly see them there is so little light.
