Mammals of Borneo; sightings from Sabah and Sarawak in Malaysia.

This gallery shows mammal observations with photos all made on B2A birding trips. The rainforests on Borneo support some of the highest diversity on earth. Without being a mammal specialist or having spent dedicated time for obtaining wildlife photos it has still proved possible to create a decent photo gallery of 47 species solely through the use of opportunity shots made on birding and family trips. Hope this collection of mammal observations may be a nice reference for anyone enjoying nature on Borneo. It may well compliment Phillipps’ field guide to the Mammals of Borneo and their ecology. This beautiful book goes far beyond identification only and is loaded with all kinds of interesting information useful for every naturalist out in the field.

Note all photos in this gallery were obtained observing full respect for the animals and nature. All mammals in this gallery are wild, undisturbed and untouched in their natural habitats. This may result in a poor record of bat and mice species as it is often not possible to observe/photo those without trapping. On the other hand this collection contains some great rarities seldom photographed. It has been a privilege to encounter the critically endangered Sabah Grey Langur. It was also equally great to find well protected Hose's Grey Langurs in Brunei, a species now completely extirpated from Sabah and Sarawak. Those 2 Langurs + Whiskered Flying Squirrel and Smooth-tailed Treeshrew were all posted for the first time by my daughter on iNaturalist as new species for the project!
