28 April 2017 – Indigo Bunting

Sad to think that this spectacular specimen of an ASY male (fat = 2) Indigo Bunting safely crossed the Gulf of Mexico a few days ago but could not safely navigate the Noble Research Center.

 

 

Indigo Buntings, of course, have no blue pigment.  Blue is produced by birds through light reflectance – it’s structural color, not pigment.

You might think, then, that Indigo Buntings would look really cool in UV light.  They don’t, unless you think charcoal looks cool!
