Overall appearance and relative size: Size and shape like a Pectoral Sandpiper but in the small end of Pectoral variation in body size
Bill: Same size and shape as Pectoral - longer than head and with a slight droop
Crown and forehead: bright rusty red with fine dark streaking, very sharply outlined from eye-stripe (which was much broader and more conspicuous than a Pectoral's)
Nape: brownish
Face: very whitish, much more so than Pectoral; white sharply demarcated from buffy on chest and sides of neck giving it a very white-faced, white-throated appearance which contrasted strongly with breast, cap - the pattern was very crisp and clean and strikingly different from a blury Pectoral face
Eye: very light prominent eyestripe (more conspicuous than Pectoral); dark line behind eye
Throat: whitish
Breast and sides: Very bright buffy - much more orange than the buffiest Pectoral. Where the throat and breast meet, there was a darker bronze collar which was apparently a row of vertical dot-like streaks but they were very fine and faint.
Belly and flanks: Whitish. Demarcation from buffy breast not particularly sharp or even
