Athough habitat destruction within its small range has not been as extensive or rapid as was once feared, apparently partly as a result of forest protection by local inhabitants, this species nevertheless has a small, decreasing range, within which its forest habitat is likely to be declining in area, extent and quality and population is likely to be declining. It is therefore classified as Vulnerable.
Turdus olivaceus (Sibley and Monroe 1990, 1993) has been split into T. helleri on the basis of its highly distinct plumage pattern, and reportedly different voice (following Collar and Stuart 1985), T. ludoviciae on the basis of
23 cm. Medium-sized thrush of montane woodland. Brownish-grey with contrasting black head and breast. Bright yellow bill. Female has streaked and mottled white throat and streaked breast.
