Cardinals are wonderful birds. They're colorful and very vocal. One of the most nurturing parents, too!
(Although they COULD try not being quite so 'vocal' outside my window at 5 am. :)
Speaking of colorful birds with a neat song; I woke up to find a Baltimore Oriole at one of the hummer feeders first thing this morning! I couldn't believe what I was seeing! I don't think I've seen one of those since I was a child.
