ABOVE: Red Langurs living in a the Sabah Softwoods industrial tree plantation at Brumas near Tawau in Sabah.
All photographs by Shavez Cheema of 1StopBorneo Wildlife who reports that the Red Langurs are feeding on both the leaves and the bark of the planted trees.
According to Sabah Softwoods most of the plantation is planted up with two different species of non-native trees;
(1) Eucalyptus pellita native to the tropical Cape York peninsula in Australia and
(2) Falcataria moluccana (Moluccan albizia) name to the Moluccas in E. Indonesia.
However it is not clear if the langurs eat the leaves of both species or just the Albizia which is a legume (bean family). Langurs are known to favour the leaves of legumes.
