From Temminck's Stint both adults and juveniles are distinguished by buffy color of underparts streaks, neat streaks on neck and craw, and prominent supercilium.

At autumn adults registered from end of June to mid-August, juveniles from mid-July to second decade of September. On Alakol lake in 1981-1993, 22 adults were netted in season from 1 July to 9 August, and 58 juveniles from 26 July to 26 August.
