Cardinals - this is one of my favorite bird photos ever. I love that cardinals stay around to brighten winter days, tho I don't see snow like this during the winter. But when the trees are bare, cardinals decorate it beautifully!
Notice the red barn birdhouse in brightly blooming summer flower garden and how the red is repeated. When the red flowers are finished blooming, the red birdhouse will still draw the eye into the garden. Color and repetition create rhythm in the garden.
