    1) I agree that it is premature to consider the possibility of sub-population structure. I have an unconfirmed sound record from 450 metres elevation (May 2019) and even if this is exceptional (which I think it probably is), then it tends to support the possibility of occasional exchange between mountains seemingly isolated by intervening lower ground.
    2) Illegal snaring was found within the Terengganu sector of Taman Negara, at 932 m elevation, meaning that poachers are reaching the core elevation for this species.

      Thanks Geoffrey: would the detection of snaring within the elevation be sufficient at this time to infer* (per IUCN guidelines) that the population is declining? My thought was not, but open to a different interpretation of the situation.
