Can't you just hear all that tweeting and chirping when you look at this bunch of birds?   My only con is that they are too colorful...no real bird has that many colors living on him at the same time.   I like the cardinal best because it is identifiable; a blue jay and woodpecker would have been equally identifiable had there been more realistic coloration.   I suggest the artist buy a picture book of" North American Birds"!   But don't get me wrong: the colors are very pleasing as they are and I really like my happy birds on a sturdy wire!
