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. source- Cornell Lab of Ornithology.
