    WIRES is short for Wildlife Information and Rescue Service. It is an Australian  organization, established(成立) in 1985 to care for injured and orphaned(失去母兽的) native wildlife. WIRES has a network of hundreds of volunteers who rescue and care for native animals until they are well enough to be released (释放)into the wild. Volunteers look after rescued animals in their own homes and are trained in the special needs of native wild animals.
    When Australians find a native animal in trouble, they often call WIRES for help. WIRES may be asked to look after a possum that has been attacked by a cat, rescue a large lizard that has got its head caught in a drink can, or care for a baby animal who has lost its mother. People call WIRES when they want to move a dangerous snake away from their garden or when they find a seabird that has swallowed(吞下) a fishing line or an owl with a broken wing. Sometimes kangaroos jumped onto the road in front of cars and are run over. Australians are encouraged to check the pouch(育儿袋)of dead kangaroos in case there is a baby in it. WIRES volunteers find themselves caring for many babies orphaned in this way.
Each year, in the summer, parts of Australia suffer from(受苦) huge bush fires. These fires not only destroy human homes and put people in danger, but they also destroy animal habitats(栖息地)and endanger the animals living in the bush. After a big fire, WIRES and other organizations go into the district to pick up surviving animals. They are treated for burns, shock, smoke and other problems and then cared for until new location can be found for them.
    WIRES is also involved in educating people in the importance of caring for wildlife and wildlife habitats. Volunteers visit schools and other public places to talk about native animals. Sometimes they bring a bat or some other interesting animals with them to show to people who may never have seen one up close before.
