Java and Bali
Javan Small-toothed Palm Civet, Arctogalidia trivirgata trilineata, Halimun Nationa Park.
I visited Indonesia for the first time in June 2010 and after a meeting in Jakarta I had a few free days before leaving for New Caledonia. I have since visited several other Indonesian islands and returned briefly to Java in 2023 when I went in search of bats around Jakarta.
Gunung Gede National Park
Gunung Gede / Gede Mountain
IN 2010 I saw Ebony (or West Javan) and Grizzled Langurs, Wild Boar, Javan Ferret Badger, Javan Mongoose, Horsfield’s Tree Shrew, Black Giant Squirrels, Sunda Black-banded (Black-striped) Squirrels and Three-striped Ground Squirrels.
West Javan Langur, Trachypithecus mauritius
There were Medium Bentwing Bats in a cave, Lesser Gymnure, Polynesian Rat, a Niviventer species, Common Palm Civet and an (introduced) Small Indian Civet
Halimun National Park
Silvery (Javan) Gibbon, Hylobates moloch
A night here produced Javan Gibbons, Black-banded Squirrels, a Black Giant Squirrel and my first Black-eared Pygmy Squirrel. After dark we had Common Palm Civet and Javan Small Toothed Palm Civet (my photos of which accidentally helped to rediscover the species).

We also saw a Malay (Stink) Badger, Red Giant Flying Squirrels, Pencil Tailed Tree Mouse and Javan Sunda Spiny Rats.
Jakarta
Javan Slit-faced Bat (Nycteris javanica), Bogor
In June 2023 I spent a night in Jakarta on my way home for a trip to West Papual. With Carlos Bocos’s help we saw a colony of Javan Slit-faced Bats at Bogor and, in the middle of Jakarta, we saw Short-nosed Fruit Bats, a Lesser Large-footed Myotis and Black Rats.
