Ecosystem engineers change the availability of resources for other species by forming new habitat or modifying existing habitat but, despite the diversity of avian ecosystem engineers, 80% of current literature focuses on mammals and invertebrates. Malleefowl Leipoa ocellata build large incubation mounds of soil and leaf-litter that are likely to provide habitat for invertebrates and vertebrates but use of their mounds by other vertebrates has never been quantified. Here, we examine vertebrate fauna visitation rates at Malleefowl mounds and non-mounds using camera-trap data collected by two citizen science projects. From 2012 to 2018, 20 active Malleefowl mounds and 16 non-mound sites were monitored over 31,913 hours and 225,144 hours, respectively. In total, we identified visits by 1724 birds, reptiles and mammals from 36 species. The mean number of vertebrate visits per 1000 hours of surveillance was around one and a half times and species richness five times that at mounds compared with non-mounds. Malleefowl mounds may enhance the availability of invertebrate prey for insectivorous birds and mammals, provide a favourable microclimate for reptiles to thermoregulate, and be signalling/social communication locations. Our results show that further research is warranted and suggest that conservation of Malleefowl may be important not only for the Malleefowl itself, but also for a suite of mallee birds and reptiles.
