The secret life of the bilby . But the real bilbies are much harder to find - living secretive lives in isolated deserts across Australia, waiting for the right conditions to start a family.

It has less calories than the real thing. Type: Journal article: Title: Diets of the re-introduced greater bilby (Macrotis lagotis) and burrowing bettong (Bettongia lesueur) in the Arid Recovery. Different diets explain how ofte. What is the bilby's life cycle? The bilby's life cycle: Bilbies start breeding at around six months old.

This Australian Ringsite is owned by Unique Australian Animals The Next Site Adelaide would catch as many bilbies as rabbits. By the 1. 92. 0s there were none to be found there. The environmental changes of the last 2. Aboriginal fire management have all had their toll. The Greater Bilby (Macrotis lacotis) now only survives in scattered patches amongst the spinifex and mulga of the northern desert areas of Western Australia and the Northern Territory. A tiny isolated group of about 6. Birdsville in Queensland. The fate of their closest relative, the Lesser Bilby (M. It was last seen alive over 7. Cute and weird. With huge rabbit ears and soft grey fur it's easy to see the resemblance to rabbits, but that's where it ends. They're so different to any other animals. They've adopted different diets, burrows, breeding habits and social networks, and this adaptability has been the key to their survival.^ to top. Opportunistic eaters. Bilbies are marsupials and members of the bandicoot family. Opportunistic omnivores, they dig for much of their food, feeding on whatever's around. They have sensitive noses which they use to sniff out bulbs, seeds, fungi, fruit, grubs, termites, insects, spiders and lizards. If the tucker runs out, they're happy to move to where the grub's better. Their resilience even allows them to survive on termites in the height of droughts. A useful trait for living in arid conditions is their ability to obtain all the water they need from food, which means that bilbies can get by without creeks or waterholes. Combined with their nocturnal lifestyle and deep burrows, their habits have allowed them to survive in arid areas, staying cool in summer and warm in winter, whilst avoiding many predators. These cautious habits also make bilbies difficult to find and study in the wild. Only emerging in the dark, they stay close to any of a dozen or more burrows they may have in an area, ready to bolt down one if their sensitive ears detect a possible threat. They're also expert excavators, and if caught out in the open they can disappear from sight within three minutes in sandy soil. In desert areas, bilbies often keep to themselves, digging simple burrows which spiral down up to two metres. Under more favourable conditions, they may live in larger loose groups with more complex warrens. Females tend to stay in a smallish area around their burrows, while males may wander a few kilometres at night, looking for a bit of . They are also found in sanctuaries and breeding colonies in WA, NSW, SA and QLD. Other info: The name bilby comes from the Yuwaalaraay people of northern NSW. They are important in Aboriginal culture and were a common food resource. Bilbies live up to 7 years in the wild and 1. They are considered endangered.^ to top. Opportunistic breeders. Females only come into season under good conditions which, in desert areas, depends on rain and food supply. In breeding colonies established in temperate areas they tend to adapt to seasonal patterns. And when the good times come, the bilbies make the most of them! A fortnight after mating the bean- sized neonate (newborn) wriggles its way to the pouch. The pouch faces backwards, so it doesn't fill with dirt while mum's digging. When it first emerges 1. Unlike other marsupials, baby bilbies rarely re- enter the pouch. The female has usually mated again, and the new neonate crawls into the pouch not long after the joey has left. Like many animals that produce young quickly to take advantage of good conditions, there's a fairly high attrition rate and only about 2. Foxes and cats will account for many.^ to top. Bilby Conservation. The bilby's last main wild stronghold is in Aboriginal lands of the Tanami, Gibson and Great Sandy Deserts area of Western Australia and the Northern Territory. Various communities through the area are working with the Threatened Species Network to carry out survey and monitoring activities, and control feral predators. Warlpiri people from Yuendumu have recently tested an ingenious new fox- baiting device that promises to be safe for dingoes, bilbies, goannas and birds. Bilbies are also being provided with safe havens such as the Peron Peninsula, WA. Alongside the dolphins of Monkey Mia, as many as possible of the original range of native animals - including the bilby - are being successfully re- introduced. And if you buy a chocolate Easter Bilby you might also be helping with bilby conservation. Proceeds from the sale of some Easter Bilbies are used by the Save the Bilby Fund to publicise and fund breeding projects around Australia.^ to top. The fight against ferals. Bilbies can hold their own against natural predators like pythons, raptors, dingoes and quolls. But to give bilbies a fair chance of survival in the wild, it's vital to eliminate as many feral predators as possible before releases into the wild. While bilby burrows were always important as refuges for a range of natives- reptiles and other small marsupials, they are often taken over by rabbits and cats. Released bilbies have spread well through the 1. Dryandra Woodland in WA and seem to be coping with predators. Part of their success is due to a local plant which produces a selective poison which kills introduced animals, but not natives. Poison Bush (Gastrolobium microcarpum) occurs throughout the South- West and consequently native mammals are tolerant to the poison. The breeding program is going so well that more releases are planned around the South- West and up into the drier areas. The Arid Recovery project in the harsh regions around Roxby Downs is trialling another innovative approach to the feral problem. After recently discovering that a group of bilbies released into the wild were killed by predators, they came up with the unusual idea of training the marsupials to avoid cats, with excellent results with bilbies in breeding programs. Otherwise have a peek at one of these rare creatures at: -SA - Arid Recovery at Roxby Downs, Venus Bay Conservation Park, Thistle Island, Yookamurra Sanctuary; WA - Dryandra Woodland SF, Project Eden on Peron Peninsula, Kanyana Wildlife Rehab Centre; QLD - Currawinya NP, Charleville Breeding Centre; NT - Alice Springs Desert Park; NSW - Scotia Sanctuary.
