I call our resident male cardinal(s) Kookaburra, not because of their “laugh” (thank heavens.. have you ever heard a real Kookaburra?) but because he truly is the king of his territory.  I’ve watched epic battles between the males fighting for the front yard feeder.  When he wins a battle he perches high on his favorite branch and sings his victory song.
I guess the loser got the back yard territory.
