Australia is a vast country. Researchers have set up automatic cameras that are snapping wildlife day and night. Now we need your help to analyse the millions of photographs captured in tropical rainforests, the dry rangelands, and around our cities. From emus to superb lyrebirds, from bettongs to bandicoots, from brush turkeys to Tassie devils, and even feral cats and foxes—scientists want to know which species are roaming both in the wild and in urban areas. The research will help answer questions including: how many endangered bettongs are left; how well native predators like quolls and devils are competing with cats for food; and how common are common wombats. So join in and help save threatened species and preserve Australia’s iconic wildlife! As well as helping us understand living Australia, you could win a Go Pro Hero 4.
