A conservation biologist wants to investigate how urban foxes interact with a newly designed 'fox-proof' food waste bin installed in a metropolitan park. The biologist uses the observation method, recording the foxes' behaviours (such as sniffing, pawing, or tipping the bin) for a duration of 10 minutes at the start of every hour between 8 pm and midnight.
Describe one weakness of using the observation method in this study.
