A very Fashionable Bird!

I was walking through the yard yesterday and noticed this in one of the cedar trees,

Now I have never seen an all blue birds nest.  And I live on 13 acres and have seen alot of birds nest's.  My husband and I were debating whether or not did the bird actually pick all the blue scrap pieces of a torn tarp, or was is just random.  I choose to think that this paticular bird did choose all blue.  If you notice the inside of the nest is made of regular nesting items, such as twigs, horse hair, feathers etc.
 I just love nature, you never know what your going to find.  I want to let you know that this nest was last years nest and I didn't disturb any babies.  It was well hidden in a ceader tree. One of Nature's Gems!
