Olifants: This camp is most deffinatly known for its Free Tailed's and has had some serious problems over the years with these bats. Unfortunately some bad decisions have been made but some good ones have made up for them. The two dominant species within the camp are Angolan free Tailed (Mops condylurus) and Little Free Tailed Bat (Chaerephon pumilus) and they can both be found roosting in the various thatch structures within the camp. Fruit bats are mostly absent from olifants however one can sometimes here the distant call of males. The camp is also utilized by Horseshoe bat Species and if one looks in dark, secluded area's you may find one or two (these species may vary from R.Simulator to R.Clivosus)
Satara: This camp is good for Fruit Bats, they are often found hanging around in the tree's and under the thatch roofs. Some other species such as Cape Serotine (Neromica capensis) and Yellow Bellied House Bat (Scotophilus dinganii) also show from now and then and one can also see the parks two most common bats, Little and Angolan Free Tailed Bats.
Skukuza: Best known for its Fruit bats (Peters and Walhbergs) this camp provides a variety of different species. I Must admit however that i have not spent a lot of time in this camp, however the suround picnic spots, Mlondozi and Nkuhlu provide amazing views of Sundevalls Leaf nosed Bat (Hipposideros caffer) in the toilets.
Mopani: I have yet to spend a lot of time in this camp but will be heading up their next week, but for now i can tell you that the two Free Tailed species rule this camp lol, however the surrounding hollow tree's can house other species such as Common Slit Faced Bat (Nycteris thebaica) and Green House Bat (Scotophilus viridis). I will provide some more information on this camp when i return in two weeks time from my trip there.
Hope this helps
