Do you know what makes birds appear blue? 💙 It’s a pigment of your imagination - this Greater Blue-Eared Starling has brown pigment, but the feathers produce a trick of the light called structural colouration. Light waves interact with keratin structures in the feathers, amplifying blue wavelengths of light back to our eyes. #EarthCapture by anthony.press . . . . #BirdsOfInstagram #BlueBirds #KrugerNationalPark #Birdspotting
