ALT A breathtaking action portrait of a male Yellow-rumped Warbler perched on a mossy, lichen-covered branch. The bird is facing right with its wings dynamically raised vertically over its back, perfectly exposing a bright, vibrant yellow patch on its lower back and rump. It has a charcoal-grey and white streaked breast, a prominent yellow patch on its flank, a thin white broken eye-ring, and a small splash of yellow on its crown. The background is a soft, out-of-focus blend of warm brown and sky blue.
