From Allaboutbirds.org., Like all other blue birds, Indigo Buntings lack blue pigment. Their jewel-like color comes instead from microscopic structures in the feathers that refract and reflect blue light, much like the airborne particles that cause the sky to look blue.

Happy Sunday friends. On Friday evening, I watched 2 male Indigo Buntings try to chase the other out of their "perceived" territory. Great fun to watch, difficult to shoot. Instead, I grabbed this shot when one landed to rest a spell. #birds #Ohbirding #BWIAB #LucasCounty #MBSP #naturephotography
