andski vivak Vanellus resplendens

Large, boldly patterned shorebird of high Andean bogs, wetlands, and lakeshores; also ranges into grassy pastures in the northern part of its range. Usually in pairs or loose flocks, feeding with typical stop-start action of plovers. Little or no range overlap with Southern Lapwing of lowlands and foothills. Note dove-gray head and breast (no crest) and pink bill and legs (duller on immature). In flight shows bold black-and-white pattern on wings and tail. Often noisy, especially when flushed.
