Range DescriptionMyophonus robinsoni is endemic to the highlands of the Main range, central peninsular Malaysia, at least historically ranging from the Cameron Highlands south to the Genting Highlands, and probably remaining uncommon to more or less common (Wells 2007). It has been recorded in at least six areas (BirdLife International 2001, Bakewell et al. 2010a, 2010b), with post-1980 records from only four of these: Bukit Larut, the Cameron Highlands Wildlife Sanctuary, Tanah Rata and Fraser's Hill (Collar 2005, Bakewell et al. 2010b). However, identification of the species has been hampered by a previous lack of diagnostic criteria for separating it from the dull southern subspecies of Blue Whistling-thrush M. caeruleus dicrorhynchus (Wells 2007, Bakewell et al. 2010a). A recent study of Myophonus species in peninsular Malaysia confirmed that M. c. dicrorhynchus occurs in montane areas, an aspect of its distribution over which there had been some uncertainty and could lead to confusion with M. robinsoni (Bakewell et al. 2010a, 2010b). The surveys for this study, conducted in 2009-2010, failed to find M. robinsoni in the Cameron Highlands, calling into question the reliability of sight records since the indisputable trapping of the species there in the 1950s and 1960s (Bakewell et al. 2010a). It appears that the only site from which the species has been recorded with certainty since 1980 is Fraser's Hill, where the species was recently trapped and sighted (Bakewell et al. 2010a, 2010b), but more searches are needed and the species may still be present in the Cameron Highlands (Bakewell et al. 2010b), or even northward from there, where there is suitable habitat for it (Wells 2007). In the absence of sufficient data, the population is presumed to number fewer than 10,000 mature individuals (Collar 2005), an estimate that recent survey results suggest is realistic (Bakewell et al. 2010a); however, further research is required.
