I can't tell you what I think he said because this is a family show! (hint - the female cardinal was nowhere to be seen 'cause I think she had a headache!).
Btw, both cardinals, as expected, showed up after sunset to enjoy a quiet supper alone at the feeder, really neat to watch them feeding in almost total darkness! Now where is everybody else?, i.e. robins, bluejays, finches, etc.
