“Young.—Similar to the old female and streaked in the same manner, 
but distinguished by having wing-coverts broadly centered with dark 
brown; crown streaked instead of being uniform; feathers black with 
yellowish buff margins, and under surface of body much more distinctly 
streaked, centers of the feathers being dark brown on throat and fore neck ; 
flank-feathers also streaked with brown.” (Sharpe.)

on the mud flats to feed, but promptly takes refuge among the reeds if 
disturbed.” (Bourns and Worcester MS.)

than subgeneric value.
