The photos (including the ones below) show a pale reddish-brown breast with washed out dark spotting.  Joern also draws attention to the white tips of the greater coverts before the speculum and the secondaries with broader white tips, also getting much paler towards the base on the outermost secondaries.  Some scapulars show narrow paler fringes.

Joern had seen this bird before and notes that the flank feathers were more greyish (above) than they had been in previous years (below).
