Dominique Brugiere let me know about this site – https://www.ecologyasia.com/ – which I don’t remember seeing before. Looks like a great resource with a heap of info on South East Asia’s mammals (and other verterbrates). Lots of small mammals – check out the bats and rats here – as well as some mammal calls.
“Ecology Asia was launched in 2001, nearly 20 years ago. It has outlived many other worthy websites, but maintains its niche in providing an easy introduction to the amazing diversity of Southeast Asia’s vertebrates. The website includes more than 800 factsheets, made easily accessible by a simple top-down menu system. And nice photos too, all taken in natural settings.”
