Our parrot, Solomon, has had his picture posted here a number of times. He is a red-lored amazon (Amazona autumnalis autumnalis), born in captivity in southern California. His ancestors came from the tropical forests of eastern Mexico. This is a close up of one of his flight feathers (technically known as remiges, from the Latin for “oarsman”). You can see the tiny barbules which interlock with each other to hold the barbs together. This photo, which covers an area about 4.5 by 3 millimeters, shows the region where the red fades into a small amount of green before transitioning again to black.
