〔http://orientalbirdimages.org/search.php?action=searchresult&Bird_ID=1448〕 The grey-crowned crocias (''Crocias langbianis'') is a species of bird in the Leiothrichidae family. It is endemic to Vietnam, where it has a highly restricted distribution in the Da Lat Plateau. Its natural habitat is intact broadleaf evergreen forest and secondary forest, generally near watercourses, between 910–1450 m above sea-level. It is threatened by habitat loss, although the species is elusive and easily overlooked, so much so that it was previously considered critically endangered. ==References== *Collar, N.
