A painted bunting is all the following: brilliant red, brilliant indigo/cobalt, brilliant lime green, purplish, and dark green. All on a bird the size of a house sparrow, and the brightest colors right next to each other without any gradation at all.
Naturally it flew away before any of us could get a camera on it. But it hung around, teasing us with glimpses of brilliant color, and occasionally flying from the fencerow trees to the brushpile, like something out of a Disney cartoon. But...I spread corn and sunflower seeds at the base of the brushpile, and near Owl Pavilion. And eventually, the bird came into view. Shutters clicked, mine among them. Of course, I had the zoom cranked out to the full 300mm, and was trying to hand-hold it steady, on a small bird in thick grass.
