Blue Jay!

IMG_7332

I was thrilled to spot a blue jay this morning. Did you know the pigment on its wings is actually melanin which means it should appear brown.  The blue appearance is due to scattering of light by modified cells on its wings (very much like the blue morpho butterfly). Blue jays exhibit erratic migratory patterns. Some migrate, some do not, some migrate every alternate year. Seems like this one is looking forward to the cold winter.
