A touch of colour.
Indigo bunting, Rondeau Provincial Park, Ontario, Canada, May 15, 2021.
A welcome touch of colour in the yard.
Passerina cyanea
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.
