The Indigo Bunting male is entirely electric blue — the result not of pigment but of microscopic feather structures that refract light — making it one of the most vivid birds in North America. It navigates on migration using the stars, calibrating its star map each year against the rotation point of the night sky. Males sing persistently from exposed perches throughout the summer.
