What crucial visual marker is visible on the wings of a soaring Red-headed Vulture that helps distinguish it?
Answer
a white 'V' or panel contrasting against the darker wing lining
Identifying the Red-headed Vulture while soaring requires noticing specific patterns on its wings, which are often more apparent than head coloration when viewed from below or afar. The key feature mentioned is a pale band that crosses the base of the primary flight feathers. This manifests visually as a striking white 'V' shape or panel set against the generally darker appearance of the bird's underwing lining. This contrast helps distinguish it, alongside its overall predominantly dark, blackish body.
