T Reardon and bat

The Friends of Scott Creek have enjoyed the company of Terry Reardon of the Batwatch group in the past, when three species of bats were netted on the one summer evening at a spot now known as Bat Watch Dam.

Terry Reardon and Stanley Flavel are the people who wrote "A Guide to the Bats of South Australia" which was originally published by the South Australian Museum in 1987 and revised in 1991. Since then and has just gone out of print, but is still found in some libraries.

Terry and Stanley have kindly allowed us to use some of the pictures from the book, which were taken by Steve Donnellan. They have also allowed us to quote from several passages.

There are twenty species of bats recorded in South Australia. Six have been recorded in the park.

They are :

  • Chalinolobus morio : Chocolate Wattled Bat
  • Chalinolobus gouldii : Gould's Wattled Bat
  • Nyctophilus geoffroyi : Lesser Long-eared Bat
  • Mormopterus planiceps : Little Mastiff Bat
  • Tadarida australis : White-striped Mastiff Bat
  • Vespadelus darlingtoni : Large Forest Bat


  The Lesser Long-eared Bat, Nyctophilus geoffroyi

Chocolate wattled bat
Chalinolobus morio

" ...It is a tree-dweller, and colonies usually number around 20 individuals.

When foraging for airborne insects it is very agile, flying and pursuing insects in dense foliage. A single young is born from October to November and is usually flying by late January. "

Chalonolobus gouldii : Gould's wattled bat  

Gould's wattled bat
Chalinolobus gouldii

" Found in most habitats, these bats are tree-dwellers, forming colonies of up to 30 individuals in hollow tree spouts, but it is not uncommon to find small colonies in man made structures. They are usually the first bats to emerge after dusk, and forage above and below the canopy for a diet often including beetles, caterpillars, crickets and moths. They emit a characteristic, audible, high-pitched sound when flying and pursuing insects. Twin births are usual... "



Lesser long-eared bat
Nyctophilus geoffroyi

" A truly adaptable species which is equally at home in many different habitats ranging from wet to arid areas. It is a tree dweller but it has acclimatized
well to urbanization. Maternity colonies are commonly found in houses and sheds, and number between 5 and 30 females. ...It is a highly manoeuverable specie, capable of negotiating thick foliage in pursuit of airborne insects. It is also a gleaner and can hover over leaves to catch tree-living insects or land on the ground to catch terrestrial insects."

Mormopterus planiceps : Little mastiff bat  

Little mastiff bat
Mormopterus planiceps

" They are fast flyers and generally forage for airborne insects above the vegetation canopy. They also feed and drink over water such as dams, creeks and tanks, and are are along the most common bats found at these sites. Little mastiff bats have an audible component in their echolocation calls which sound similar to that of white-striped mastiff bats, but not as loud or as metallic in sound. "


White-striped bat
Tadarida australis

" This species is found in a wide range of habitats and is quite common in urban areas. It usually forages above the vegetation canopy but is reported to occasionally land on the ground to feed on terrestrial insects.
... White-striped mastiff bats have a loud audible component to their echo locating calls rendering them easily detectable in flight to people with good hearing. The sound is like that made by sharply tapping two tweny-cent coins together at a rate of twice a second. "

If you are interested in becoming involved in the study of bats, Terry and Stanley recommend the Mammal Club of the Field Naturalists' Society of South Australia (Inc.) as a good starting place.
