Abstract Urban areas are growing rapidly across the globe. Such environments present specific challenges to wildlife. Resources can be highly fragmented in space and time, accompanied by specific risks and opportunities that can emerge from proximity with humans. Overall, these have been shown to lead to specific activity patterns in wildlife, which tend to restrict their space use accordingly to avoid encounters with humans. Yet, some foraging opportunities supplied by humans can also attract wildlife. Urban-dwelling species would therefore benefit from learning when and where to exploit human derived food. Here, we investigate how birds exploit areas of different degrees of urbanization and if they do so with specific time patterns. We used the example of feeding sulphur-crested cockatoos ( Cacatua galerita ) in Sydney, Australia. We combined tracking birds to identify key resources, and a citizen science approach to investigate human-wildlife interactions in the urban landscape. Our data suggest that SCC do not use all parts of their home range equally, but use green spaces as roosting and foraging areas, while facultatively using more urbanized areas at specific times when they are the most rewarding. This implies a role for sophisticated time and place learning, with birds matching activity to human patterns. This study builds on the literature investigating human-animal interactions, expanding our understanding of animals’ exploitation of human behavior. Our results highlight the unique opportunity that studies on urban wildlife have for understanding urban biodiversity establishment, maintenance, and cognitive ecology.
