In
August 2004 HERG team members Elizabeth Chamberlin and Samuel Veloz,
University of California, Amanda McLaughlin, Tufts University, and Craig
Smith, Department of Primary Industries and Fisheries, conducted a disease
surveillance operation in central Queensland, Australia. The operation was
targeted at a colony of little red flying foxes roosting amongst mangroves
in South Tress Inlet, south of Gladstone. Photo: C. Smith.
The
primary goal of the operation was to ascertain the prevalence of antibodies
to Hendra virus within the population and attempt to isolate any virus that
might be present. Eighty four little red flying fox pups, born only 3 months before,
where caught, sampled and safely released over several nights. A small blood
sample, urogenital and oral swabs where taken to allow HERG team members
at the Australian Animal Health Laboratory to test for the presence of
antibodies and virus. These results will be used by HERG team member Dr
Raina Plowright, PhD student University of California, to study the
prevalence of Hendra virus in little red flying foxes and understand how the
virus maintains itself within flying fox populations. Photo: C. Smith.
Both Elizabeth and Samuel also
collected information during the operation to assist with their PhD
projects. Elizabeth collected hair samples from the flying foxes which will
be analysed for naturally occurring radio isotopes, these isotopes will
used to identify what regions within Australia the flying foxes have
inhabited within the previous 6 months. Samuel performed flora surveys
throughout the region and will use satellite imagery to determine the
presence of flowering eucalypts, the preferred food source for the little
red flying fox, which will assist in predicting the movement patterns of the
little red flying fox. Photo: C. Smith.
Take a virtual tour of South Trees Inlet. Place your cursor on a waypoint on the map below for information and click for picture. Waypoints of interest include panoramas (4 and 27), primary trap site (28), secondary trap sites (5 and 29) and a little red flying fox pup (20). Map: C. Smith.

Watch videos from the operation including catching little red flying foxes and fly-out, when flying foxes leave their colony after sunset to begin their nightly foraging.
Whilst
in central Queensland, HERG team members received assistance from flying
fox rehabilitators Suzanne and Henry Grzegorski and Queensland Parks and
Wildlife Service Senior Wildlife Ranger Tim Farry and Wildlife Ranger Graeme
Russell. Tim and Graeme are currently surveying flying fox colonies which
will soon be protected under the state Flying Fox Conservation Plan. Photo:
