Just as soldiers on sentry duty constantly adjust their behaviour to match the current threat level, dwarf mongoose sentinels exhibit flexible decision-making in relation to predation risk, new research from the University of Bristol has shown. Biologists Julie Kern and Dr Andy Radford found that decisions about when to go on duty, what position to adopt and how long to remain on post were all affected by information about the likelihood of danger. Sentinels altered their behaviour depending on both environmental conditions, such as wind speed and social signals, such as alarm calls.
