List of Resources for Understanding, Living and Management of Flying Foxes

rescued orphan flying fox in careThe recent outbreak of the potentially deadly hendra virus is a cause of great concern to horse breeders and farmers alike. According to the Department of Primary Industries, although the virus can be transmitted from horses to humans, found in bats, there is no evidence that it can be transmitted directly to humans.  Flying foxes are critical to the environment and a protected species. Culling is not only cruel but also ineffective.  (Ref: Flying Foxes and Hendra Virus;   The role of flying foxes in Hendra virus)

There are many effective steps people can take in reducing the risk of horses and people getting infected. See:

Reducing the Risk of Hendra Infection in People

Flying foxes are the only flying mammals and perform the quintessential task of pollinating and dispersing seeds of many native plants. Many trees especially those with white and green fruits rely only on flying foxes for pollination and dispersal of seeds. Losing our flying foxes would also mean losing a vast range of our native plants.

Flying foxes are also responsible for nutrient regeneration and nutrient cycling within the ecosystem, (Ref: Living With Wildlife) by providing large quantities of natural fertiliser across the landscape. They also create gaps in canopies enabling ground- dwelling plants to get more sunlight and rain.

Building Bathouses For Microbats

microbatMicrobats are natural insect terminators.  These little mammals  weigh around 3gms  - 150 gms and have a wingspan of approx 25 cm. Being nocturnal creatures they use echolocation to navigate and find their insects in the dark. Contrary to popular myth, the bats are not blind and do use their sight as well.  The largest species has a body length of only 11 cms.  A single microbat can eat  up to 1,200 mosquitoes and small insects in an hour which has earned them the well deserved reputation of being the nature's mosquito busters.  They also pollinate native flowers, many of which can only be pollinated at night. Microbats like their bigger cousins the flying foxes (also called megabats) are a vital part of the ecology of our forests and planet. Recent surveys in Australia have shown that in grain-growing regions, the microbats fed solely on grain weevils, thus helping crop protection by reducing the use of pesticides.  Microbats also eat midges, termites, lawn grub moths and other harmful insects.

The Real Facts About Bat Transmitted Diseases

courtesy Bats Qld and Long Grass Wildlife Refuge Centre

 

Grey flying foxThe incidence of Australian Bat Lysavirus (ABLV) in wild bats is about the same as the incidence of HIV in humans: between .09% and 1.2% of free-living population (1,2)

The instance is higher in sick animals that come into care. Bats with ABLV always die.

Responsible for two deaths (one of whom refused treatment). Post and pre-exposure treatment is 100% effective - not one vaccinated person has died from ABLV.

ABLV is saliva-borne and lives a short time outside the body.

ABLV kills. Vaccination is ESSENTIAL. In every continent except Australia and Antartica veterinarians, carers and members of the public are routinely vaccinated.

Humans catch Hendra (originally equine morbillivirus) from horses, not bats

No bat carer has ever caught Hendra. Screening 128 long-term bat carers found none had detectable antibodies (Selvey at al., 2006)

Bats do not suffer from or die from Hendra, but authorities have found antibodies in the amniotic fluid of bats and suspect they may be a host for the disease.... however

"This is all speculation though as we know that bats carry the virus but we don't know exactly how it gets into horses." Dr Stephen Prowse (2008), CEO of the Australian Biosecurty Cooperative research Centre for Emerging Infectious Disease

Gabi's Baby Bat Creche and Adult Release at Batavia

by Gabrielle Friebe from Bats Qld

batsqld.org.au

Batavia is a bat creche recently constructed at Woodford, on the way to the Sunshine Coast on Queensland.  2010/2011 bat season has certainly presented us with a few challenges with babies, flooding, extreme weather conditions and more.

Batavia Bat Rescue Creche

 
Challenges were fairly well to be expected when we think about the delay in getting the release aviary up and running due to weather with still a lot of necessary features ‘undone’. We had to fishing net the whole aviary inside, install more noodles and cover them as well of course for soft landings.

baby bat clinging to mother bat

Flying foxes and Microbats are placental mammals

They are warm blooded and deliver a furred open-eyed baby and suckle their young

The baby has oversized feet and an extra hook on the thumb hook to aid in clinging to its mother

 

By latching on to the mothers teat located in the wing pit the baby is carried very securely for the first five weeks of its life

From 3-5 weeks the baby cannot thermo regulate

Bats mothers are meticulous in hygiene and use their tongue to lick and groom the baby

Baby bats CANNOT fly until they are 12-13 weeks old. Many calls for rescue come after a baby has been seen for days and this seriously affects its survival.
