Just a bit of sunshine

lights up the bright blue of the indigo warbler. posting late again . most of you probably know the blue in a bird feather is not pigment but is due to light scattering in the feather due to the arrangement of the barbs.kind of like a mini rainbow that gives you the blue band .at the wrong angle  or without enough light these look almost black. 
to paraphrase one of my former residents ( who said punctuation happens to other people-ie on the computer typing front) sometimes capitals happen to other people for me.
