These photos look correctly identified from the overall proportions and tail patterns. If the LHC in the link above is representative, it seems that young LHCs show streaking and then transit to barring in the underparts while HHCs change from juv. streaks to more rufous, finer streaking of the adult. The bird in question seems to show very slender proportions i.e. looks more like LHC to me... but I won't bet on it!
