Primates list rankings

Although there is much more to mammalwatching than listing species, it is – for many of us – a fun way to track our effort. Mammal listing is nothing more than a friendly competition. But I believe it can motivate mammalwatchers and also lead to a more interactive and lively community. So if you have a list please share it here. Any questions about what people have seen or where? Just click on their list and ask them.

My recent new species was Spectacled Galago in Uganda. A predictable highlight was Eastern Gorilla. I haven't added either Thomas's or Demidoff's Dwarf Galago to my list as I'm concerned about identification. If anyone has information beyond size and movement I'd be most interested to hear it.

It's actually been a while since this list was added to. Vietnam primates are a definite highlight. I really just wanted to be in the top 10 of the primate lists and reside with the other esteemed mammal watchers here while I could. Shameless I know. Cheers.
