Comparison of adult-type Richard's Pipit Anthus richardi 'sinensis' (1) and adult Blyth's Pipit A. godlewskii (4). The population group A. r. 'sinensis' occurs in southeast China south of the Yangtze River. Structurally, 'sinensis' is the smallest group in Richard's, with proportions recalling Blyth's. Note however the blackish centers to the median coverts (2, 3). In adult-type Richard's (2), the centers are triangular and tinged rufous at the edges. In adult Blyth's (3), the centers are squarish, less rufous-tinged, and more clear-cut. 1, 2: Nanhui, 15 Dec. 2016. 3, 4: Hulunbeier, Inner Mongolia, 22 July 2015. Craig Brelsford.
